Welding Copper Youtube. In the past we have looked at TIG Brazing copper but in this video we show you ho. The welding of thick copper sections requires a high preheat due to the rapid conduction of heat from the weld joint into the surrounding base metal.
Youll also want to use either argon or helium gas. 450 nm wavelength and 2000 W laser power CW open up new possibilities for spatter-free and high-quality laser welding of copper. The welding of thick copper sections requires a high preheat due to the rapid conduction of heat from the weld joint into the surrounding base metal.

The heat required for this type of welding is approximately twice that required for steel of similar thickness. Published on May 5 2011. Copper welding is more difficult compared to metal welding. Most copper alloys even in thick sections do not require pre-heating because the thermal diffusivity is much lower than for copper.
