Spiral weld vs butt weld?

05/14/2010 4:50 AM

Can someone please tell me why we use spiral weld instead of circumferential butt welds? What is the advantages of spiral welds? Thank you.

What do you mean by spiral and circumferential butt weld?

It might also be helpful to know your application. Are the terms showing up in a document you are using?

I do not mean to be derogatory but I do not recall neither terms even though they're might be a proper ones in some parts of the world. The only spiral weld process comes to mind is the one that some manufacturers use in their larger gauge pipe making, as opposed to longitudinal fusion technique used by other manufacturers includidng RHS profiles also. The spiral one is supposedly stronger but it comes down to again the standard.

Isti: a butt weld (at least where I am), is one where the sections of piping, etc. to be combined are placed end to end, and a single, circular weld is done all around the seam. There are often seen at the joints between lengths of pipe and pipe fixtures, since they typically interface at 90 degree angles.

I interpreted the sprial weld reference the same way you did. Are we perhaps discussing different ways of creating long lengths of pipe? i.e, a continuous, spiral welded length versus several butt-welded short sections of it?

You've got me on the butt weld.

I got confused of the circumferential term and did not think of the pipe which is what the term relates to naturally.

As for using spiral welding technique to make heavy gauge pipes some manufacturers do that however, I saw in class during my training, other manufacturers just curl up length wise a metal strip and after they weld it straight up. It might get grounded for better finish though.

Do you mean the difference result or effect in moving the rod in a spiraling tract, instead of circular, or oscillating between the objects to join?
