Butt weld.

01/17/2011 11:48 PM

Hi,

Really, I couldn't find any measurement for the protrude of material when you do bevel welding - half bevel (1/2 V). That is the normal bevel welding (no concave, no convex), and when finishing the welding, it must have a little welding material protrude out the groove. In some cases, we need to know the height/length of the protruded metal.

Could you give me some tracks to find out, pls. Thank you very much!

Go here and read this.

You will find that the "R" (Reinforcement) is that little bump of weld metal above the flat surface of the pipe wall shall not exceed 1/8"

Hi,

If for pipeline you may refer to API 1104 - 7.8.2

the reinforcement (weld cap) should not be more than 1/16" (1.6mm)
