High-Frequency Inverter Robot Welding Cell for Aluminium, Iron Wire Mesh and Copper Tube — 40-200KVA, PLC Programmable, 6+6mm Capacity

Fire door manufacturing, wire mesh fabrication, and copper tube assembly share a common challenge: the materials involved (aluminium, galvanized iron mesh, copper) have vastly different thermal and electrical properties. A conventional AC spot welder struggles to deliver consistent nugget quality across these materials on the same production line.

This Xinwei HF robot spot welding cell solves the problem through high-frequency inverter technology. The 1000Hz inverter delivers a fast-response, precisely controlled current waveform that can be programmed per material type. The industrial robot provides flexible part positioning for complex geometries like fire door panels. The PLC controller stores welding recipes for each material and part variant, enabling quick changeover between aluminium, iron wire mesh, and copper tube assemblies on a single production line.
