A Change in weld progression using GTAW
A Change in weld progression using GTAW
(OP)
As per ASME IX
QW-405.3 - A change from upward to downward, or from downward to upward, in the progression specified for any pass of a vertical weld, except that the cover or wash pass may be up or down.
I understood that a change in weld progression is a nonessential variable but my question with regard to the statement above is:
What is meant by "except that the cover or wash pass may be up or down."?
Does it refer to the weld capping?
Thank you in advance.
