The 2016 Cadillac CT6 is the first fruit of General Motors’ labors to perfect the idea of spot welding between aluminum and steel. The process eliminates the need for rivets between the different materials, cutting costs and added weight in the process.
But, GM won’t keep this technique in house. WardsAuto reports GM will happily license out the technology. The patented technology includes a GM engineered welding tip, which still fits to conventional welding tools. Therefore, new setups are not required, only the welding tip.
As for GM, it will begin to use the technology increasingly more in upcoming product. During the automaker’s lightweighting debrief, it announced the technology will soon be applied to seatback construction, followed by vehicle hoods.
