Weld defects
Thread Content
Brother, look at the appearance of this weld to see if there are many defects, such as undercuts, etc. I don’t quite understand.
Isn't there anyone who can help me? I suggest you take more pictures and enlarge them.
I don’t know much about welding, but you can see from the picture that the undercut height is not high enough and spatter is not polished. Look at the edge line. If you suspect there is undissolution, you can look inside the weld.
Without a bevel, it would be difficult to weld through.
The weld reinforcement is not enough, there are undercuts, and the spatter needs to be polished.
