So, when tig welding, how thick materials can be fitted up tightly, to be able to penetrate trough? From how thick material I should leave a gap from material to the second material? From how thick material there should be a bevel(as I understand, that chamber on the edge?) on the edge, and should that beveled material be fitted up tightly or left with some gap from the other beveled material? Is there a nice way to bevel pipe at home with some basic tools involved? Does it change with different joint types, or with different materials or with something else?

I hope everyone understands the question, and I hope this thread will be informative for everyone with the same question.

Thanks already guys!

 

for me...

I never intentionally gap anything and I bevel anything thicker than .065 wall.

I bevel everything by hand, it gets to the point where you can probably do it with your eyes closed. a belt sander is the easiest for this.

 

is there a way to bevel using hand grinder? or only with belt sander? And when you bevel, how much flat edge you leave? like if that wall is .065, when you put a chamber on edge, how much thickness is left without chamber(hope you get what I mean)?

 

you can hand bevel with anything. even a hand file.

as far as specifics on the "land" area (the flat part that isnt beveled that you are referring to) that I cant really give any. You will need to see what works best for you. Sometimes i weld with no filler and have a steep bevel with a big land. sometimes I weld with mig wire (.035, .024) as filler and other times I use 1/16 or 3/32 rod so if you can imagine they will fill in differently. there are so many variables even down to how you weld that will change things.

 

Ok, thanks for tips

Someone else with some input???

 

bump?

 

More information? Anyone???

 

well a soft rule is, you want to have the size of bevel pretty close to the thickness of the material, and as stated before the landing is going to depend on the welder because of the essential variables (ie torch angle, filler thickness etc) and on large diameter pipe you would want to leave a gap for a root pass, on this stuff not so much.... oh, and not being a dick, but its chamfer not chamber.

 

Ok, thank you
