FF's Welding Progress

[Furious Filipino]

Hey all, trying to salvage my welding progress thread before the whole issue with Photobucket wanting so much for web hosting. Posts here I'm guessing will be fairly infrequent at first, but as soon as I remember to actually bring a camera into the shop that I'm not afraid to break/melt, I will start documenting more frequently.

Photos above are from the end of my first semester of Stick and Flux Core program. 3/8" A36 mild steel with 1/8" gap at the root with a backing bar.

I was able to transfer a few more testing photos from May this year.

2 coupons for MIG and 2 coupons for TIG, all in the flat, 1G position. Can't quite locate the before grinding photos, so I may update later.

Root and face bend for each coupon. One of the coupons failed with a full length crack that didn't develop until the very last few degrees of the 180 degree bend test. It was the root bend on the MIG plate.

really hard to tell much about a weld after you have taken a grinder to it.
But if it don't break after bending 180 degrees, you must be doing some thing right.
Just keep burning and you will always get better. Rich

That's actually the standard AWS procedure for testing welds. They are bent in this fashion after grinding flush to remove stress risers. Any defects show themselves very quickly.
