Line 292:
*** Subsequent passes (called fill) are made with a normal welding technique to fill up the grove to just below surface. Alternating sides and directions will help reduce distortion
*** Final pass(s) (called the cap) are made with a much wider than normal weave to finish off the surface and to leave it protruding 0-3mm as for other welds.
** Very thick materials (8mm+)
*** Standard short-circuit transfer MIG is not recommended on materials >8mm thick
*** It will be very hard to get enough heat into the work to achieve full fusion
*** Spray transfer is recommended, although globular transfer might help
* Lap joints of dissimilar thickness and dealing with burn-back issues
* Using tip-dip
