OEM Linking Pin: 2018 Buick Regal MIG Brazing

As part of the I-CAR Repairability Technical Support (RTS) OEM linking pin activity, we are helping to connect the collision repair industry to the vehicle makers. The roof of the Buick Regal is laser brazed from the factory along both sides of the roof. In repairs, Buick repair procedures require MIG brazing to replace the laser brazed seam, a first from GM. Recently we had a technical inquiry that asked if adhesive bonding, instead of MIG brazing along both sides of the roof, could be used to replace the roof.

Per our contact at GM: "The referenced procedure is approved for all regions where the vehicle is sold. At this point in time there isn’t an approved adhesive procedure for this vehicle."

There are different procedures on the wagon and the hatchback. The hatchback must be MIG brazed the entire length of the roof, whereas the wagon’s procedure calls for spot welds in certain locations along the sides of the roof and MIG brazing the remainder of the seams. Both procedures also call out several adhesive and spot weld locations to complete the repair.
