Spec calls for a 3/8" fillet weld on an A-36 ring to be welded to a resulfurized 1144, 3 1/2"...
We are multiple pass GTAW (tig welding) 304L and 316L SS piping of various diameters and thicknesses in the rotated 1G position. In the smaller diameters (1" through 8") we would like to speed up the process with an interpass air/water mist cooling of the rotating assembly to less than...
