Offer up and align (Panel repairs)

5. Apply seam sealer or structural adhesive, as applicable, to panel joint surfaces. See INFORMATION, Sealing and corrosion protection.

Offer up and align

Offer up new panel and align with associated panels. Clamp into position using welding clamps or Mole grips. Where a joggle or brace joint is being adopted, make a set in the original panel joint edge or insert a brace behind the joint.

NOTE: In cases where access for welding clamps is difficult, it may be necessary to use tack welds.

Welding

1. Select arms for resistance spot welding and shape electrode tips using a tip trimmer.

CAUTION: Use arms not exceeding 300mm in length.

NOTE: To maintain efficiency, the tips will require regular cleaning with emery cloth.

2. Fit resistance spot welding arms and test equipment for satisfactory operation, using test coupons. Where monitoring equipment is not available, verify weld strength by checking that metal around the weld puddle pulls apart under tension during pulling.
