Welding Carbon Steel To Copper. Pipe using gas metal arc ERNiCu-7 wire and 100 argon then TIGed the CuNi to itself. It can be bought from a company called Arcos.
Is this practical and or durable. Plate angle and bar stock for general fabrication. Thank you-----who knows how long that weld will hold up.
A TIG welder is used when welding copper to give the weld seam the best appearance and a leak-free bond.
Mild steel accounts for a large segment of welded parts of Industry where good plasticity and ductility is required. In the heavier thicknesses first overlay or butter the steel with the same filler metal and then weld the overlayed surface to the copper. Clean and flux the area to be silver brazed. I tried searching through the forum with no success.
