Copper Heat Sink Welding

Heat sinks are usually made from aluminum or copper.

Copper heat sink welding.

Due to the impact of extrusion capacity of extrusion. Copper can be very usefull to use as a backing bar when welding thin materials partiularly stainless steel it will conduct the heat away into itself and act as a chill this will help to reduce the amount of distortion make sure the copper chill is in close contact and that the mating sufaces are clean to avoid weld contamination aluminium and to a lesser degree brass can be used but if the arc touches them you risk root contamination ok to back up on a lap weld though. Let s talk about the main differences between them. Aluminum is the most common material for heat sinks.

Each has its own advantages. Copper welding heat sink is designed to welding the fins on copper base by environmental protection lead free medium temperature soldering process. Copper is even sometimes for backing instead of argon. If you grasp that fact and utilize it using copper for heat sinks is one of the best tig welding tips ever for welding stainless steel sheet metal.

The fins can be folded fin l fin zipper fin or fins with heat pipe and the material is generally al6063 al6061 c1100 etc. In particular extruded aluminum heat sinks fit the needs of most projects.

It is not quite the same or as good as shielding the back side with argon but sometimes its good enough and its a lot easier and cheaper. We don t need to discuss design specifics here since that s not the point. Copper welding heat sink is designed to welding the fins on copper base by environmental protection lead free medium temperature soldering process. Aluminum alloy has been widely used in electronic industry because of its good thermal conductivity.
