Steel and copper and copper alloy welding What is the cause of the crack?

Steel and copper and copper alloy welding
What is the cause of the crack?



One is the effect of high thermal conductivity. Copper thermal conductivity than carbon steel 7 to 11 times, when the use of technical parameters and welding with the same thickness of carbon steel, the copper is difficult to melt, filled with metal and base metal can not be well fused.


Second, the welding joint hot cracking tendencies. Welding, the pool of copper and impurities in which the formation of low melting point eutectic, copper and copper alloy with a significant thermal brittleness, resulting in hot cracks.


The third is to produce stomatal defects much more serious than carbon steel, and if the hydrogen hole.


Four welding joint performance changes. Grain coarsening, plasticity decreased, corrosion resistance decreased.
