Socket Weld Vs. Butt Weld

The butt weld and the socket weld are two different ways to weld two pieces of materials together. 

•  Butt Weld

 A butt weld is two pieces of materials butted against each other and welded. Several different methods 

 exist for beveling the two pieces for good weld penetration. Both flat stock and pipe or tubing can be 

 butt welded. Generally, the weld is ground flush with the material surface.

• Socket Weld

A socket weld involves two different sized pieces of pipe. The smaller one is inside the larger pipe. The 

 weld is completely around the outside circumference of the larger pipe.
