Hi there,

Frankly to say, I am not quite sure about your question. If you are asking for the WPS qualification, please take a look at QW-451.2. Your overall base metal range will be 1.5~20. For filler metal, GTAW range is 1.5~4; SMAW range is 1.5~16. You can use them both or use one process only.

Hi,

Tony, your reply is correct, except when Impact testing is required, the thickness limits need a revision.
In general, each process can be used in the limits of qualification.
