Racing Industries Utilizes the latest Seam Welding and Automated MIG welding techniques for manufacturing catalytic converters. MIG welding is used to weld pipes to catalytic converter bodies. This automated procedure mechanically rotates a catalytic converter body while using gases and special copper wires to weld on the pipes.

Seam welding is the latest and most intelligent welding technique used in the production of catalytic converters. The top and bottom shells of Racing Industries converters are seam welded together.  In this process two pieces of metal are infused together with electric and water. This technique ensures the converter body will be air tight and is also the most cost effective and efficient welding method today.
