Currently, the resistance spot welding process is already in place on the Cadillac CTS-V as well as the liftgates of the Hybrid variants of the Chevy Tahoe and GMC Yukon, but GM has plans to ...

Instead of joining aluminum parts with rivets and industrial adhesive -- as Ford does to assemble the redesigned 2015 F-150 -- GM is rolling out a new welding system. GM's system spot welds ...

Well, GM's new resistance spot-welding process uses a patented multi-ring domed electrode. The new process saves about 2 pounds of rivets in aluminum body parts. Want to see it action?

GM tested the water when it put an aluminum liftgate on a Tahoe hybrid in 2008 and tested its ability to do aluminum-to-aluminum spot welding. Today it is a manufacturing staple at GM, ...

According to the Detroit-based automaker, the resistance spot welding process, which GM says is an industry-first, is expected to enable more use of the lightweight metal on future vehicles, which ...

Spot welders are used in the fabrication of automobiles, PC cases, power supplies, microwave ovens, electrical junction boxes, Faraday cages, and various electronics. A spot welder is used because … ...

General Motors just announced a new welding process it already implements in some cars that allows for increased use of the lightweight material, ultimately offering improved fuel economy.Using a ...
