Welding around corners ?

I've often seen it discussed here but wanted some furthur info . Can someone explain why or why not too? Are there any exceptions or ways to do it properly in certain situations?

 

that's not a very specific question, but here's a couple of answers.

It's not a good practice to continue welding around a corner because you really need to reposition your hands to maintain the same torch angle, relative to the joint. Rarely will you find yourself in a position to do this seamlessly.

As to welding corners, it makes me think of welding tabs on a ch***is. Unless the tabs are really thick, you should achieve penetration nearing the thickness of the tab by welding one side, so it's redundant to weld both sides of a tab. It also raises the possibility that you will get undesireable tempering of the metal in a sensitive area.
You do, however, want to weld around the end of the tab to close the joint, making a u-turn at the end. That closes any opportunity for a fissure at a critical spot.

 

I usually use a big mirror and brace myself on the wall , that way I can see exacly what i'm doing

 

I usually try to make it a little way around the corner, makes it look alittle better. I would think It would be best to have a continous bead all the way around though. If you have sharp angles stress consentrations will gather there. Wouldnt it be better to weld all the way if possiable?

A lot of times when working with Square tubing I will do all 4 corners about 3/8" each way then come weld to weld on the strait run. That keeps my hands and weld angle in good a position at all times.

My Dad could throw a shoe (15,WINGTIP) around a corner.

 

I would anticipate the corner and position your body position accordingly. If possible. I think it's good practice to go through the motion as a dry run first, especially in complicated situations.
