Hey there everybody!
I have to specify an electrode to weld two stainless steel pipes that run into a heat treatment oven on a galvanising line. This pipe is one of the channels where the gas is burned inside to provide heat to the oven interior.
Since my weld knoledgement is kind of low at this point, i'd like to know if you can help me to specify this SMAW electrode.
Both tubes are:
Stainless Steel
C - 0,45 @ 0,55
Cr - 24 @ 28
Ni - 33 @ 37
W - 4 @ 6
Co - 14 @ 16
All in %
Thickness of tube, 7.9mm
Any idea?
