Low Temp Weld Procedure

Low Temp Weld Procedure

Low Temp Weld Procedure

(OP)
Can I use a low temp weld procedure for A106 material?

RE: Low Temp Weld Procedure

Not sure what you mean by low temperature welding procedure. Most welding procedures are for general application related to base materials being joined, and with and without impact qualification.

RE: Low Temp Weld Procedure

My question is why you would need a low interpass technique on cfe pipe?

RE: Low Temp Weld Procedure

Please start a new thread. Suggest you re-state your question and refer to low interpass temperature, not technique, and spell out cfe.

RE: Low Temp Weld Procedure

Welding procedures qualified per ASME IX with low temperature impact tests can be used for materials not subject to impact testing.

RE: Low Temp Weld Procedure

Weldstan is correct but I would add that WPS' developed and written for impact tested applications are needlessly restrictive for non impact applications.

RE: Low Temp Weld Procedure

Is the material listed in the WPS? Is the Material listed in the WPQ?

If the answer is no to either one. NO.

RE: Low Temp Weld Procedure

P No. is the essential variable for non-low temperature applications not the material specification.
