Be gentle if this is a completely stupid idea.
Have almost zero welding skills on thin steel and to make matters worse a HF 90amp Flux wire feeder unit.
I get around ok with thicker material but at Minimum switch setting I guess it still pumps out to much juice.
attempting filling up holes on 040" scrap rec. Copper disc at back of hole . Looked good I thought but as it cooled I could see a space. Space proved troublesome to fill.
Thought of using another copper disc on the outside, but cut through like a washer. Figured the Weld has to stay within it's confines. Hell of a weld , seems like hole is really filled this time.
I'll know for sure after I grind the Steel and copper off !
The inside of the Rec. though looks bad, almost like 3 Islands within the hole diameter,.
The idea I had-- Finally-- was to get small chips off the Mill, --same steel and pack them in the hole, firmly up against the Copper backing plate.
A much smaller copper plate , just a bit bigger than the Hole maybe, to be placed on the outside.
Clamp firmly with the Spotwelder and Cook it !!?????.
Would the chips Melt and flow ?
Would it work, and who would know ?
Appreciate your thoughts.
