Radiograph 1" plate test 3g

Postby Woodbutcher » Fri Feb 05, 2016 10:08 pm

So im training for an X ray 3g on one inch plate. I suppose my instructor is doing the best he can with me, and I see improvement every week, however I cant help but wonder what other folks think about this test and what i should expect, any advice is welcome.

Slag inclusions and voids and pieces if tungstens if you stick and break off the tip are the only things I know of that show up on x Ray.
I have more questions than answers

Just keep it clean and let the plate cool.

Here's mine.

Just a couple welders and a couple of big hammers and torches.

Well akyour welds look great, was your root pass completed in the 3g position? It looks like its flat on the bench.

My instructor, god bless his heart is scrutinizing every ripple in the weld. Which is some times discouraging to say the least. I havent seen any ripple-less welds. I guess I wont know for sure until the results come back from the state.

I assure you every pass was 3g vertical up.

You'll get it.

Again, the welds look great. By the amps stated im assuming you were using 1/8 rod. Your root pass is making me think im not holding long enough in the toes, my root doesnt look as thick or as full. But I am feeling more confident because the rest looks very similar to what im seeing in the booth, thanks for your time and encouragement.

Yeah 1/8" rods.
I think I used 3 different welders ansd 3 different brands of rod throughout the plate.

Weld as hot as you can on the root, and jam the rod tight into the edges.

This is my root pass, I decided to try two stringers instead of a weave, they are laying much flatter than my weave in the root. Sorry it took so long for me to get pictures. I'll get some more uploaded.

This is a little more than half way out, double weave as you can see. I'm running Lincoln Excalibur 1/8 rod at around 120amps with a Miller cst250 inverter machine. Any advice is welcomed.
