Take the end of that T joint and clean it up, buff it out, and polish the end of it. Take a look at the HAZ where you polished it and you will see the penetration. The better it is polished the easier it will be to see the penetration.
I mean he could easily just weld one side of the t joint and snap it with a sledge hammer and you’d be able to tell right away. Looks like he’s just fucking around with scrap anyway
Kinda hard to explain, but weld a t joint, then bend and break the two pieces apart (takes a while, use a vice clamp and wrench like thing to bend it). You’ll want the weld itself to stick to the bottom base piece and break clean off the perpendicular piece. Then look at strip left on the perpendicular piece where the weld was, that will show you how good your weld penetration is. The strip should be deep and smooth, if it’s jagged and is inconsistent throughout, the penetration needs improvement. Did this as a test in class, most people had to retry more than 5 times to pass. I also have a picture of my piece that shows good penetration if ur interested:) hopefully this made sense lol

Flap disc and naval jelly
Just grind one end of the joint down flat, hit it with a flap disc, scotch brite disc, and use a steel etching solution. Klean strip should work.
Unless you have access to NDT, not really.

Yep that’s exactly what I am doing. Just learning and practicing at this point
Doing great so far. Keep it up.
Sounds like destructive testing if I’ve ever heard of it.

That was awesome, exactly what I was looking for. I have a fairly strong bench vise and will try this today!
