Welding stainless steel to carbon steel 8

[apetr26542]

I apologize if this is a redundant post, but I need to specify the proper electrode for welding a 3/4" diameter stainless steel rod (304) to a schedule 40 steel pipe. This will be done in the field and is part of a life line attachment.

Usually the filler metal used for weld SS to CS would not work well with whipping. whipping is a technique used with certain fast freeze steel electrodes.

Whipping can be done with SS electrodes but the arc is just NOTHING like an E6010 or 6011.

Depending on the application, the mixture may not be a problem.

JLG III,

Can you explain/describe what you mean by "whipping"?

 

[pipewelder1999]

It's a technique where the electrode is moved forward and up from the puddle to allow it to cool and to volitize some of the material in front of the progressing weld.

I think I understand (at least in principal) what you were trying to accomplish, but, relying on whipping to avoid zinc contamination sounds like a dangerous practice.
