What type of welding is used to produce assemblies?
A- Currently the most popular weld process used with hydroformed tubes is Mig welding. Both Gas Metal Arc Welding (GMAW) and Flux Core Arc Welding (FCAW) are in wide use by most hydroform manufactures. The chief advantages Mig welding has over other alternatives is it only requires single sided access which in turn allows high density of welds, and low capital and operating costs. Spot welding shares Mig weldings low costs, but limits design flexibility as it requires access to both sides of the joint. This drives the need to pierce holes in one side of the tube to provide access for the weld tip to the joining surface. Laser welding can also be employed to join stampings to tubes or tube to tubes with a minimum of heat distortion. High capital and operating costs are currently the major stumbling blocks preventing wider use of laser welding. As the technology improves and costs are reduced the process will see greater use.
