For future reference, would a small backing purge box work for this type of thing, if I position it on the backside of each weld as I move along?

Thank you for your help.

Sorry. I am not sure of a good way to clean up the backside of the weld joints(the inside of the bin). Is there a commonly used “pickling gel” (passivation agent?) that works for this type of thing? This is totally a non-critical project. I am getting practice in anything I can. Thanks in advance fo...

I welded up a bin out of some scrap stainless for practice and shop organization. I am going to try to finish the outside for practice as well.

After basic instruction or welding course and working the first welding job(or the first few) what improvements allowed you to receive a better wage?

I have been meaning to make a burn bar.

Would I need to use a heavy gauge material for the chute or am I going to be burning it up to often to ...
