Low Temp Weld Procedure 1

[Downhand]

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

 

[metengr]

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.

 

[ledon]

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

 

[metengr]

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

 

[weldstan]

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

 

[weldtek]

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

 

[lsone]

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

If the answer is no to either one. NO.

 

[weldstan]

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