1. What exactly is a Mesh Welding Machine?
A fully automatic mesh welding machine is an automated welding device that continuously welds metal wires to form metal mesh sheets of various specifications. DAPU’s heavy-duty rebar mesh welding equipment, standard building welding equipment, and various fence mesh welding equipment all fall under the category of mesh welding machines. These production lines integrate automatic raw material feeding, automatic welding, and servo-driven mesh pulling, making them widely used heavy-duty equipment in modern construction, road construction, and industrial protection industries.
Servo Driven Trolley: Workers insert raw materials into the feeding cart, and a servo motor stably and precisely feeds them to the welding system. DAPU’s feeding cart automatically returns, allowing workers to continue inserting wires. This design can increase output by up to 2 times.
Horizontal Wire Dropping System: Raw materials are straightened and cut to a fixed length by a cutting machine and placed into the dropping system. SMC cylinders control the precise dropping of the materials into the welding system. DAPU’s dropping system has a high load-bearing capacity, capable of supporting up to 1 ton of rebar at a time, thereby reducing the frequency of worker material feeding.
Welding System: At the intersection of the longitudinal and transverse wires, a powerful current is converted into heat through welding electrodes, fusing the two wires into a strong weld. DAPU’s pneumatic welding system uses Japanese SMC multiplier cylinders to apply pressure to the welding electrodes (one cylinder connected to one welding electrode), resulting in stronger welds and a smoother mesh.
Servo Mesh Pulling System: The welded mesh is linearly pulled out. Automatic winding and cutting systems are available to meet the needs of our customers. DAPU’s servo mesh pulling system uses Taiwanese brand cable chains and racks, ensuring precise pulling, cyclic pulling, and a long service life.
Major Applications and Use Cases
Construction and Civil Engineering: High-strength steel mesh for construction, frequently used in cast-in-place concrete structures, precast components, floor slabs, walls, roof supports, and other critical infrastructure.
Transportation and Infrastructure: High-load-bearing tunnel support mesh and road surface crack prevention mesh, frequently used in bridges, tunnel support, highway pavements, airport runways, and other infrastructure.
Safety and Protection: Various standard and non-standard fencing panels, frequently used in military and government fencing, farm fencing, highway guardrails, factory fencing, private residential fencing, and other areas requiring high-security protection.
HVAC and Civil Use: Production of underfloor heating mesh panels (insulation layer fixing mesh), frequently used in radiant floor heating (underfloor heating) systems.
2. What are the main types of wire mesh welding machines on the market?
Before purchasing a wire mesh welding machine, the most important thing to understand is the types of welding machines available. They are categorised into various types based on different dimensions. Choosing the right welding machine depends on the type of raw material, wire diameter, level of automation, and other special requirements of the mesh (winding/cutting).
Wire mesh welding machines are classified by automation level into fully automated production lines and semi-automated welding machines.
1. Fully automatic wire mesh welding production lines integrate functions such as automatic wire feeding, straightening, welding, linear pulling, mesh turning device, mesh dropping, stacking, and packaging. Through a precise PLC programming control system and a user-friendly human-machine interface, they achieve improved production efficiency and precision control, making them suitable for companies with high requirements for increasing output and saving labour costs.
2. Semi-automatic wire mesh welding machines typically require manual wire insertion and manual handling of the welded mesh. Initial investment is low, but labour costs are high, making them suitable for industry newcomers with limited budgets.
Classification by raw material wire diameter: Large-diameter steel mesh welding machines, standard construction mesh welding machines, fine wire mesh welding machines, small-hole welding equipment, precast component welding equipment, and other special-shaped welding equipment.
Large-diameter steel mesh welding machines primarily weld 5-12mm steel bars. DAPU engineers designed pneumatic welding technology with a powerful welding transformer and cylinder pressurisation system, along with a cooling system, ensuring strong welds. They are mainly used for load-bearing mesh in concrete structures.
Standard construction mesh welding machines primarily weld 3-8mm steel wire. Unlike heavy-duty steel mesh equipment, the wire is in rolls. They can be used with shearing and rolling systems to produce construction mesh and rolls, offering high flexibility. They are typically used to manufacture various standardised construction meshes or customised safety fences and guardrails.
Fine wire mesh welding machines primarily weld 2-4mm steel wire. They offer fast welding speeds, and the mesh is mainly used for assembling poultry cages, mining support netting, etc.
Small-hole welding equipment is mainly used for welding fine wires of 0.4-2.8mm. The equipment is small, occupies little space, and is easy to maintain and operate. Due to the high flexibility of the mesh, it is mainly used for DIYing various special types of decorative mesh.
Precast component welding equipment comes in various types. DAPU mainly produces four types: brick strip mesh welding machines, ladder mesh welding machines, hoop bending machines, and rebar column welding machines. These machines offer high production speed and precision, primarily used to shorten project construction time and improve the overall durability and safety of building structures.
Other special-shaped welding equipment: This type of equipment is usually specially developed to meet customer needs. DAPU’s factory produces cable tray mesh welding machines, filter pipe mesh welding machines, and small shelf welding equipment to meet diverse customer requirements.
3. Compared to traditional welding methods, what are the core advantages of using a fully automatic welding machine?
Doubled Production Efficiency: Fully automated wire mesh welding machines produce twice the output of semi-automatic equipment, offering stable operation and shorter delivery times.
High Welding Precision: PLC programming and touchscreen control of the entire production line reduce manual intervention, resulting in precise welding with minimal errors.
Reduced Labour Costs: Fully automated wire mesh welding machines require only 2-3 operators to operate and supervise the equipment.
Low Energy Consumption: Utilising medium-frequency inverter technology, fully automated wire mesh welding machines save electricity and reduce raw material waste, achieving environmental friendliness.
High Return on Investment: High initial investment but low subsequent maintenance costs lead to long-term profitability.
4. When choosing a wire mesh welding machine, what are the most important technical parameters?
After selecting the type of equipment we need, the next step is to evaluate whether a fully automatic welded wire mesh machine has optimal performance. This requires understanding the equipment’s technical parameters from the supplier, as these parameters determine the equipment’s production efficiency and product quality.
1. Maximum/Minimum Welding Diameter: Understand the range of wire diameters the equipment can weld to confirm whether it can weld normally at its maximum or minimum wire diameter.
2. Welding Speed: Understand the equipment’s production speed, usually expressed as welds per minute. This is the most important parameter for calculating production efficiency, but welding speed will vary depending on wire diameter, mesh size, and mesh width.
3. Mesh Aperture Accuracy: Understand the mesh aperture error range of the equipment’s welding. This value is crucial and is the sole parameter for judging mesh quality; the lower the value, the better.
4. Number of Transformers: The larger the welding diameter, the greater the required weld strength. More transformers mean more power and a stronger weld.
5. Rated Input Power: The equipment’s power requirements are an important indicator of its energy consumption.
5. How to Ensure the Quality and Strength of Welded Joints?
The strength of the weld joints is the core of production. A good quality mesh can only be said to have weld joints that do not loosen when pried with a wrench. Ensuring good weld joint strength relies on the following three core technical elements:
Type of Welding Transformer: Medium-frequency transformers are the most commonly used in modern mesh welding machines. Previously, power frequency transformers were used. With technological reforms and innovations, it has been found that medium-frequency technology can provide a more stable and faster output current, eliminate sparks, and provide a stronger welding force.
Powerful Pressurisation Method: To maintain uniform weld joints, the same pressure needs to be applied to the welding electrodes. For example, the DAPU mesh welding machine uses a cylinder pressurisation method, with one cylinder connected to one welding electrode, making the weld joints stronger and eliminating incomplete or weak welds.
Efficient Water Cooling System: The welding process generates enormous heat, requiring an efficient water cooling system to protect the lifespan of the welding system. The DAPU mesh welding machine uses a thyristor-controlled water-cooled transformer and electromagnetic valves to control water cooling and pressurisation, forming a complete and high-precision welding control loop. Ensure the stability of the machine under high-speed, long-term working conditions and the strength of the solder joints.
6. What are the differences in operation and programming between fully automatic mesh welding machines and CNC mesh welding machines?
A fully automatic mesh welding machine uses a CNC control system, but it emphasises a higher degree of automation; while a CNC machine emphasises a human-machine interface based on a PLC and touchscreen, enabling autonomous welding.
In simpler terms, a fully automatic mesh welding machine includes a CNC control system, but the emphasis is different.
7. What is the machine’s energy consumption/power consumption? How is the production cost per unit of wire mesh calculated?
These are the questions customers are most concerned about. How do I calculate the cost? How do I calculate the retail price of the wire mesh? These questions require customers to calculate electricity costs, labour costs, maintenance costs, and other losses.
Unit wire mesh cost = Depreciation cost / Wire mesh production output
8. For specific materials or special mesh sizes, does the mesh welding machine need to be specially customised? What are the main parts that need to be modified?
For specific materials or non-standard sizes, mesh welding machines cannot simply be modified by adjusting parameters; rather, they require special mesh customisation and optimisation for the structure and core components:
Stainless Steel Mesh Welding Machine: The resistivity and thermal conductivity of stainless steel and galvanised wire differ significantly from ordinary carbon steel. Key modifications include:
Electrode Material: Highly conductive and corrosion-resistant electrode materials (such as chromium-zirconium-copper alloys) must be used to prevent contamination during welding and ensure stable current transmission.
Welding Procedure: Shorter welding times and smoother current ramps (slew rates) are employed to prevent plating burn-off or intergranular corrosion of the stainless steel.
Special Mesh Customisation (Large Span/Small Pitch):
Large Span Mesh: The machine’s structural rigidity needs to be strengthened, potentially employing a segmented or gantry structure to ensure that feeding and shearing accuracy does not decrease with increased width.
Small Pitch Mesh: Extremely high requirements are placed on transformer heat dissipation and electrode arrangement, necessitating dense water-cooled radiators and high-performance power supplies to prevent heat accumulation.
9. How can a wire mesh welder be integrated into an existing automated production line?
Precision welding is controlled by a PLC. After welding, the mesh is transferred to a CNC shearing or bending machine via precise sensors and a robotic arm, enabling continuous processing of the mesh.
10. What is the approximate budget range for purchasing a high-quality, fully automatic wire mesh welding machine? What are the main factors that affect the price?
The price of a high-quality, fully automatic wire mesh welding machine is not fixed and cannot be judged solely by price.
Entry-level or semi-automatic welding machines, such as small electric wire mesh welding machines, are relatively inexpensive.
Mid-range standard semi-automatic equipment, such as wire mesh welding machines equipped with only an automatic welding system, an automatic weft wire feeding system, and a servo-driven wire pulling system, is moderately priced.
High-end fully automatic heavy-duty CNC equipment, such as rebar mesh welding machines with automatic sheet turning and conveying systems, will significantly increase in price.
Main factors affecting price:
1. Brand influence: Undoubtedly, fully automatic wire mesh welding machines from major European brands, such as Schllatter, Schnell, and EVG, typically cost over a million US dollars. They are leaders in the wire mesh welding machine industry, and their prices are naturally high.
2. Level of automation: Higher levels of automation naturally lead to higher prices.
3. Welding technology: DAPU offers mechanical, hydraulic, and pneumatic wire mesh welding machines. Different welding methods result in different prices.
4. Wire diameter of the raw material: The larger the wire diameter, the greater the welding current and heat required. The machine must be equipped with a larger capacity, higher output welding transformer, resulting in a higher price.
4. Brand of electronic components: DAPU welding machines typically use domestic and international brand electronic components, which offer high precision and long lifespan, but also come at a higher price.
5. Customisation needs: Customisation requests from customers also require paid design and development.
11. How do you calculate Return on Investment (ROI)?
Purchasing a fully automatic wire mesh welding machine is a very important investment. We need to learn how to calculate the return on investment and see if the equipment can bring net benefits in the long run.
Return on Investment (ROI) Calculation Formula
In the above formula, “Total Cost Savings” is the core driver of the high return on investment for fully automated mesh welding machines.
Labour Costs: Fully automated welding equipment reduces the number of personnel. Only 2-3 operators are needed per machine, which is key to cost savings.
Material Waste and Scrap Rate: In traditional welding methods, manual intervention leads to inaccurate welding, incomplete welds, and missed welds, resulting in 5%-10% waste of raw materials. DAPU fully automated mesh welding machines operate the production line through PLC programming and touchscreen control, using servo motors to precisely control wire positioning, reducing the scrap rate to 1% or even lower.
Time Value and Cost Recovery: Increased production efficiency shortens delivery times, improves the recovery of outstanding payments, and allows for a quick recovery of equipment costs.
Energy Efficiency: Modern fully automated equipment generally uses medium-frequency inverter technology, significantly reducing electricity expenses.
12. How capable are the suppliers of after-sales service, operational training, and spare parts supply? How important is this for long-term use?
