Welding of SB171 to SA 333 Gr 6
Welding of SB171 to SA 333 Gr 6
(OP)
We will be fabicating a Heat Exchanger wherin the shell material is SA 333 Gr 6 and the Tube Sheet material is SB 171.
Joint configuraion of tubesheet to shell weld is a corner joint. Have not worked before with SA 171 and would like some information regarding WPS/PQR quals for Sa 333 Gr 6 to SB 171. what sort of electrodes/wire to be used current voltage etc.

The brass tubesheet will require a local preheat of 500 deg F, with a maximum interpass temperature of 600 deg F. I don't have any specifics on welding parameters. I would contact one of the welding supply companies to obtain this information.
