Dear fellows,

In ANSI /AWS A3.0 STANDARD WELDING TERMS , there is a term: BACKUP ELECTRODE that I don`t know where it uses, can anyone give me any idea??

regards.

After reading the A3.0 myself, I'm going to hazard a guess....   I think it is referring to the bottom half of a resistance spot welding electrode assembly.

The backup electrode (often stationary) is on one side of the sheet and the primary (pogo) electrode is on the other.  The primary electrode brings the pressure force.

Lawrece,

It is a very good opinion, I figured it was related to resistance welding.

thank you

Hello Lawrence, is there a possibility that this could also refer to Electro-slag welding, there is a shoe that is used for starting the process and possibly this could also be referred to as a " backing electrode"? This is a bit off the cuff, but wondering about the possibility. Best regards, Allan
