Hi!
If you have already welded the joint with increased weaved bead and you want toi accept the same in such situation you have to
i) Do you require Impact for weld ? if yes carry out the mock up with same parameter of welding used and test the coupon (It should meet the requirement)The same results can be converted in to PQR
ii) If the weld does not require Impact, in such case Heat input is not essential and check the hardness of HAZ and weld ( and it should be in acceptable range) .,Check for crack, by UT/RT .this way you can ensure the soundness of the weld and accept

Thank Q all
If weave length is increased what will be corrective action
By taking Hardness values can we accept the weld?
Please advise
