in normal course of operation we re-tube 4 to 5 large construction equipment cylinders a month at work always have the staff welders do the weld out on the finished parts , but they were all out on a emergency repair and this one had to get done , I was pretty happy with the results , tig welded the root and cover passes
its normal working pressure is only 2500psi so we static tested it to 10,000 and held it for one hour like normal proved out fine ,
just for giggles we sent it out to be " radiographed " not sure what that is but the boss said it would tell us how good the weld was ,.
