6061 T-6 Aluminum Tank repair on Nozzles
(OP)
We have an aluminum tank that we recently inspected that has leaks on previous repairs on the nozzles. The repair plan is to remove the existing nozzles and bad welds, and replace them in kind. The tank thickness is .25". What is the best weld process to ask the repair company for? GMAW, GTAW, or SMAW?





RE: 6061 T-6 Aluminum Tank repair on Nozzles
If the tank is to be taken out of service and placed in a shop, GTAW or GMAW are both acceptable procedures that are capable of producing positive results.
If the tank is to be repaired in the field, GMAW is highly recommended vs. GTAW, but is dependent on conditions (wind, position, etc.).

Ageing may help a little, but temperature control will be extremely difficult.
