| Abstract Scope |
The concentration of residual elements such as copper in the steel scrap cycle is steadily increasing with the rise of mass electrification of automobiles, appliances, and other consumer products. Accumulation of copper is of particular interest due to its difficulty in removal during liquid steelmaking in the electric arc furnace, as well as its tendency to cause “hot shortness”, a form of liquid embrittlement, during thermomechanical processing at oxidizing temperatures. For copper-bearing steel products that do not exhibit hot shortness, their behavior in downstream manufacturing processes is not well understood. For surface-sensitive processes such as welding or coating, the effects of copper can be prominent due to its enrichment at the steel-scale interface during thermomechanical processing. This work aims to assess and quantify the influence of copper content on both the arc and laser weldability of low carbon plate and sheet steels. |
