Been watching, reading, practicing as much as possible to continue chasing the perfect tig welds. My question comes to knowing at what point your “good” is good enough? Have any of your guys ever sent any welds out to do any testing on them? Watched “Mr tig” on youtube weld some .049 T joints and them took them to a college where they did a Magnetic particle test. Here is the link
They identify two areas on his weld, but never tell you if they’re acceptable or not. It was rather disappointing to be honest. This is the guy that teaches the classes at EAA if I’m not mistaken and for the test to reveal a potential problem it makes me wonder. Watch the videos, the welds and technique look pretty normal. Nothing magical that I’m seeing
I called a local Non destructive testing shop in Wisconsin and we talked for 10 minutes or so and he said if I were to bring in some test/practice welds they would be using a penetrant dye as he didn’t think chromoly was magnetic. (His words, not mine).
I vaguely remember Cameron setting up a hydraulic jack to do some destructive testing on a few practice pieces. I think he was just trying to see if the tube failed before the joint. I don’t believe there was any way to measure how much force was applied. On second thought though is it even necessary to have any number? As long as the tube breaks first your good?
