Repair Methods For Partial Replacement
All spot-welded bonded joints and some bonded joints can be replaced if a repair is required with welded joints.
Do not make the repair with only the same weld points and seams as originally used in production, because these alone are not adequate.
NOTE:
If the instructions call for additional weld points, these should be applied in one step.
Do not place additional weld points between the original weld points.
Gas-shielded arc plug welding should only be performed after spot-welding, this prevents any increased shunt current when spot-welding.
Ensure good weld penetration at all connections.
Seal off repaired flanges and apply cavity sealant.
