The AWS tried, for the most part, years ago to eliminate the terminology "Reverse" and "Straight" Polarity. Welders (operators) have not let go of the terminology. There is much correct information on the responses to the question. The important fact that I either missed or was n...

Excellent machine. Set it up as you were doing steel. Tungsten same, polarity same, so forth and so on. Once you have determined the length of the cracks and their severity then drill holes at the end of the cracks to stop the propagation of the cracks. If the holes are not beginning from an edge th...

Berend, can you submit a drawing of the (simple sketch) with items listed as in your post? I would suggest back-step welding technique with the addition of alternating welds from one end and opposite sides of attachments to reduce or eliminate distortion. I may also suggest a temporary internal supp...

The first thing we need to know is what is your welding experience and process ability? It could be Oxy-fuel brazed or GTAW with silicon bronze rod. First the crack should be dye penetration tested to see where the crack ends and starts. Sometimes the human eye cannot see the extent of the cracking....

Drill the holes completely through. Cut the pin length less 1/16 inch. Place the pins in the holes and weld from the back side filling the space left by the recess with the GTAW process. Weld at low amperage and you should not have a problem with your heat treatment. Do not allow too much weld conve...
