How to weld aluminum
7. maj 2024
Some metals, like aluminum, have a naturally occurring, tough surface oxide layer. That surface oxide layer must be removed to enable successful welding. In the case of aluminum alloys, the surface oxide layer has a significantly higher melting temperature (approximately 2000°C) than the melting temperature of the aluminum base material (660°C).
