DAPU wire mesh welding machines are designed in various types to meet the needs of different fields. Heavy-duty reinforcing mesh welding machines are suitable for high-strength rebar mesh produced from pre-cut steel bars. high-capacity steel bar welding machine uses high-speed, coiled steel bars as raw materials and focuses on efficient mass production. high-capacity construction mesh/roll welding machines are widely used in fence and safety fields.

The DAPU mesh welding machine production line adopts a modular design and can be flexibly configured according to the customer’s demand for full automation. Each module is an independent system with clear functions and is easy to combine and upgrade. The core modules of the mesh welding machine include the line wire feeding system, the cross wire feeding system, the welding system, and the automatic mesh pulling system to ensure the efficient completion of basic production needs. At the same time, to improve the level of automation, auxiliary modules such as the automatic cutting system, the automatic mesh rolling system, the automatic sheet turning Process, and the automatic stacking system can be selected. This modular structure not only improves the flexibility and scalability of the production line but also can tailor-make optimization solutions for customers to meet different production scales and automation requirements.

These mesh welding machines have different functional focuses but essentially use the same resistance welding principle to firmly weld raw materials such as steel bars into meshes through precise current and pressure control.

1. Basic principles of resistance welding

Resistance welding uses the resistance heat generated by the current passing through the intersection of metal wires to locally heat the metal to a molten or plastic state, and then applies pressure to complete the welding. This process includes the following steps:

  • Power on: A large current is supplied to the intersection of the metal wires through the welding electrode.
  • Heating: When the current flows through the metal wires, a high temperature is generated due to the resistance of the intersection.
  • Pressure: Applying pressure at high temperatures causes the metal wires to fuse at the intersection.
  • Cooling :After the power is turned off, the metal wires cool under pressure to form a solid weld.

2. The main welding process of the mesh welding machine

①Wire arrangement:

Longitudinal wires (warp wires) and transverse wires (weft wires) are arranged at specified intervals.

The warp wires are usually fed through a wire-laying device, and the weft wires are fed one by one by an automatic feeding system.

②Positioning and clamping:

Longitudinal wires and transverse wires are fixed at the intersection position by mechanical or pneumatic devices.

The welding electrode clamps the intersection to ensure concentrated current transmission.

③Current heating:

A high current passes through the intersection for a short time, and the metal is melted by resistance heat.

④Pressure welding:

The electrode applies pressure to ensure that the metal is completely fused and the weld is strong.

⑤Cooling and moving:

After welding, the machine moves the mesh to the next welding position and repeats the above steps.

3. Features of mesh welding machine

  • Precise control: Through PLC (Programmable Logic Controller) and touch screen, the current, heating time, and pressure are precisely controlled.
  • High efficiency: Multi-point synchronous welding, welding multiple intersections at a time, greatly improving production speed.
  • Strong adaptability: The mesh size, wire diameter, and welding parameters can be adjusted according to needs.

Reliable quality: The welding points are uniform and firm, meeting the use requirements in the fields of construction, industry, and agriculture.

4. Influence of welding parameters

  • Current: affects the melting degree of the solder joint and needs to be adjusted according to the wire diameter.
  • Power-on time: too long times may cause overheating or deformation of the solder joint.
  • Pressure: insufficient pressure will cause the solder joint to be unstable, and excessive pressure will damage the wire.

5. Construction Mesh Applications

Welding mesh machines are widely used in the production of building steel mesh, guardrail mesh, cage mesh, mine screen mesh, etc., with the advantages of high efficiency, energy saving, and stability.

These building meshes are widely used in construction projects and infrastructure construction. It has the characteristics of high strength, strong durability, and simple construction, and is an important material for improving building quality and construction efficiency.

In concrete structures, building meshes are often used to reinforce floor slabs, walls, foundations, columns, and beams, which can effectively enhance the tensile properties and overall stability of the structure. In addition, in infrastructure projects, building meshes are widely used in the reinforcement and protection of highways and railway roadbeds, as well as bridges and tunnel linings, to improve bearing capacity and extend service life.
