Can you weld on a metal case that contains electrical components?
Ok so i work on avionics and today we found a crack in the case of a large relay panel that contains resistors, relays, diodes, and other componets. I was wondering if we could get it welded without removing all the guts. Some of the components are case grounded
No (not with the electronics still attached). You are working on an aircraft component made of aluminum. It will have to be Tig welded. The high frequency used in (AC) Tig welding will fry any electronics within the case. It is safer to remove the case. I have seen Tig destroy a computer 30 feet away so don't take the chance.
