I bought some decent mma 316L rods off ebay and the seller added some unmarked rods. When I use them they burn well, produce a lovely looking stainless steel weld but when I do a destructive test on a butt or lap join the weld snaps right across the middle without much effort. They are gray in colour and have black tips. Anyone know what they are plz? Think I should bin them? Brian (",).
Wyn's reply....They could well be hardfacing rods. The colour of the weld can look very similar..and it probably wouldn't hold two bits of metal together.
