41 00... Opening Weld Joints

WARNING: This page is about a different car, the 2010 BMW X5, 2009 BMW X5, 2008 BMW X5, and 2007 BMW X5. However, it is still accessible from the selected car via links, so may be relevant.
  1. Opening weld spots (resistance pressure spot welding): 
    • 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.

      Or open weld spot with Vario Drill spot welding cutter (refer to WORKSHOP EQUIPMENT & PLANNING CD , Chapter 7).

      NOTE: Because the weld spots may have surface-hardened, grind them if necessary with an angle grinder and paper grinding disk.
  2. Opening laser weld seams: 
    • Place angle grinder with grinding disk on laser weld seam and grind through top metal sheet. Be careful not to cut through and damage sheet metal underneath.
