Retrofits Boost Welding Precision and Control

From Miyachi Unitek Corporation
 

 

Resistance welding aluminum to tight military specifications can be a challenge for aerospace manufactures. Extremely precise process control is essential for consistent results, but aluminums' inherent properties (high conductivity, fast oxidation) make this difficult to do. One way companies are dealing with the problem is by retrofitting existing equipment with new inverters. That's what Six Sigma supplier Triumph Components, San Diego, did - with great results.

"Inverter-based resistance welding power supplies boosted productivity, improved weld quality, and rapidly evolved into a competitive advantage," affirms company president, Mark Gobin.

The firm works on a range of tight-tolerance, high-temperature aluminum alloys that are bulge, hydraulic, and drop-hammer formed. It joins components into complex assemblies such as primary exhaust systems, pneumatic ducting, bleed air ducting, and plugs and nozzles.
