[Column] Reasons Why Welding Copper is Difficult: Key Points for Each Method and When to Perform Them

It is also necessary to preheat the base material to reduce the effects of heat! An explanation of copper welding.

Copper is weak against heat and tends to soften easily at temperatures above 200°C, making welding work difficult. Additionally, due to its high thermal conductivity, heat tends to escape from the base material when the welded area is heated. Moreover, during welding, attention must be paid to defects such as cracks and blowholes. Suitable welding methods for copper include gas welding, inert gas welding, laser welding, and brazing, and it is important to set methods and conditions that match the size and shape of the base material. This article clearly explains the reasons why welding copper is difficult, the welding methods, and key points during the work.
