The thermal conductivity of pure copper is about 8 times that of soft steel! A considerable amount of preheating is required for welding materials.
"Steel" has a thermal conductivity of pure copper that is about 8 times greater than that of mild steel. As a result, the welding heat that is applied rapidly diffuses to the base material side, making the weld joint less compatible. Additionally, it is characterized by a higher likelihood of defects such as poor fusion and slag inclusion. To achieve sufficient penetration, considerable preheating is necessary, and the width of the heat-affected zone also becomes significantly larger. [Features] - Higher likelihood of defects such as poor fusion and slag inclusion - The thermal conductivity of pure copper is about 8 times that of mild steel - Significant preheating is required to achieve sufficient penetration - The width of the heat-affected zone also becomes significantly larger For more details, please contact us.
