Photos of bad welds

Welding really is a fascinating subject, and we’ve all seen the beautiful ones but shockingly bad welds still pop up despite all the knowledge, training and experience that’s out there.

Weld profile shown in this photo is a SMAW process, not GTAW process.

Which imperfections you are found?

That weld looks pathetic all the way.

That’s GTAW Bien, I was the inspector on the job. They started doing FCAW because they were having so much trouble. There’s porosity, lack of fusion, undercut and underfill. That was just small picture of a very long seam/joint.

Terrible, the resident welding engineer and I had a lot of trouble with those welders.
