I acquired a few old interesting welding rods and would like to know more about them. What are they and how they are used.
- A bunch of silvery, soft rods looking like tin saying "universal mould". by Welco.
- Approximately 2.5 lbs of grey "tungsten wire", 3/32", eighteen 36" pieces. by Sylvania. Looks like pure tungsten to me. Is that "tungsten filler rod" for actually welding tungsten metal objects?
- 410 S/S filler rod. I think that digitalmaster mentioned that it can be used for welding any stainless, just not for most critical applications, can it also be used for joining stainless to mild steel?
- Mystery rods labeled 1/8"-36" 1220-A. They are hard metal, harder to scratch with a pocket knife than ER70S2.
- Alloy Rods Company filler rods labeled in writing "oil hard." Not very hard material when scratched with my pocket knife.
- More rods by same company labeled "hot work".
I am quite intrigued by them and will appreciate any clues.
thank you
