1. Opening Weld Spots (Resistance Pressure Spot Welding): Procedure

WARNING: This page does not describe the selected car, but rather 31 other vehicles, including the 2015 BMW Alpina B7L, 2015 BMW Alpina B7, 2015 BMW 750i, 2015 BMW 750Li, and 2015 BMW 740i. However, it is still accessible from the selected car via links, so may be relevant.

If necessary, surface-grind existing unevenness with a belt or angle grinder in the area around the weld spot.

Set punch mark in center of weld spot. Set 8 mm dia. weld spot drill bit on punch mark and drill through top metal sheet.

NOTE: Because the weld spots may have surface-hardened, grind them if necessary with an angle grinder and paper grinding disk.

Use a chisel to separate the sheet metal flange and remove the component.

Follow the special procedure for SPOT WELDS  .
