Automatic Multi-Head Spot Welding Machine for Wire Mesh and Steel Bar Production

A versatile automatic multi-head resistance spot welding system designed as a flexible production platform for industrial wire mesh, steel bar grids, reinforcement mesh, fence panels, and custom metal mesh products. With 17 synchronized welding heads, 40-200KVA power range, PLC programmable control, and automatic pneumatic electrode pressure management, this machine adapts to diverse product specifications — from light wire mesh for fencing to heavy steel bar grids for construction. The gantry-style moving workpiece design along the X-axis enables continuous automatic production with consistent weld quality, making it the ideal upgrade for manufacturers seeking to increase throughput, reduce labor dependency, and expand product capability with a single welding platform.

Key Production Advantages

1. 17-Head Simultaneous Welding for High Throughput
Seventeen welding heads operate in parallel, welding multiple joint intersections in a single cycle. For a standard wire mesh panel with 30 cross-wires, this parallel configuration reduces welding time by over 70% compared to sequential single-point welding. The result: significantly higher daily output without additional labor — critical for manufacturers bidding on high-volume orders.

2. Flexible Product Capability
Unlike single-purpose machines locked to one product type, this platform switches between wire mesh, steel bar grids, reinforcement mesh, and fence panels by loading different PLC presets. Wire diameter range of 3-6mm accommodates light fencing wire up to heavy construction-grade steel bar. The gantry-style moving workpiece system ensures consistent weld positioning regardless of product dimensions — one machine, multiple revenue streams.

3. Automatic Pneumatic Pressure Control
Each welding head features independent pneumatic pressure regulation, maintaining consistent electrode force throughout every weld cycle. This eliminates the quality variation common in manual or mechanical pressure systems. Benefits: uniform weld nugget formation, reduced splash defects, and extended electrode life — all contributing to lower per-panel production cost and higher first-pass yield.

4. 40-200KVA Scalable Power Range
Available in D(N)B-100 through D(N)B-250 configurations covering 40-200KVA. The modular power design allows you to match the machine to your product mix: lower KVA for standard wire mesh and fencing products, higher KVA for construction-grade steel bar grids up to 6+6mm. Scale up as your business grows without replacing the entire production line.

Frequently Asked Questions

Q: What products can this machine produce?
A: This is a flexible multi-product platform that produces industrial wire mesh panels, steel bar grids, concrete reinforcement mesh, fence panels, storage rack mesh, protective screens, and custom welded wire structures. The PLC stores multiple product presets for quick changeover between different specifications — wire diameter 3-6mm, various mesh sizes, and panel dimensions.

Q: How does multi-head welding compare to single-head machines in production output?
A: With 17 welding heads operating simultaneously, all cross-wire intersections on a bearing bar are welded in one cycle instead of sequentially. For a typical 2m wide mesh panel with 25-30 cross wires, multi-head welding reduces cycle time by over 70%. This translates to 3-4x more panels per shift compared to single-head machines — the difference between fulfilling or losing high-volume contracts.

Q: Can I switch between wire mesh and steel bar grid production on the same machine?
A: Yes. The PLC system stores separate presets for wire mesh (typically 3-5mm wire, finer spacing) and steel bar grids (4-6mm bar, wider spacing). Changeover between product types takes under 30 minutes including electrode adjustment and parameter loading. This flexibility allows you to serve multiple customer segments with one capital investment.

Q: What support do you provide for installation and ongoing production?
A: Standard delivery is 25-45 working days. On-site installation and commissioning takes 5-7 working days including PLC programming for your specific products, production trial runs, operator training, and maintenance instruction. Remote pre-commissioning and ongoing technical support are included.
