If my welder is qualified with groove, which means qualified for pipe of diameter 73mm and above. Can I use that welder to weld set through nozzle, if nozzle diameter is less than 73mm, lets say 50mm? My doubt is due to the groove present in shell not on nozzle.
Good Day!
We are going to proceed for the welding of the Above ground Storage Tanks (Service Water, Raw Water, Potable water, fire water),,
Please, What's the required Qualifications for this type of welding? WPS & PQR & WQT
Thanks
