Thank you very much for your response. The reason I am asking the question is that our welders have asked to do the root uphill for better penetration and the filler passes downhill on their WPQ.
I understand that if you write a WPQ and say all uphill or all downhill then change to the other they need to re-qualify but can you write it as root uphill and fill downhill?
If the WPQ states root uphill and filler downhill and you have two supporting WPS MH-1 which is uphill and MH-2 is downhill could you use both combined on one WPQ?or can you not have uphill and downhill in the same WPQ
The WPS is for proving that a weld is sound and the WPQ is for proving that the welder is capable of making the weld you ask for, So if you ask for uphill root and downhill filler is that ok?
I’m new at this and appreciate your help very much.
