If there are other issues regarding access to mating fa-
ces, the various replacement options are described in
the basic instructions for structural bodywork repair
(see MR 400).
Lines (1) , (2) and (5) on the drawing show a butt weld
by continuous EGW welding.
The welds described in this procedure are all identical.WARNING
If the mating faces of the parts to be welded are not
accessible, make EGW plug welds to replace the
original resistance welds (see MR 400).
