ALUMINIUM WELDING

The most common commercial aluminium and aluminium alloy welding methods use an electric arc with either a continuously fed wire electrode with DC current, with and without pulsed current] or a permanent tungsten electrode plus filler wire [with AC current].The arc is protected by argon gas (or argon-helium gas mix) to shield the weld pool and the electrode from the surrounding atmosphere. Arc welding is easy to use, attains a high temperature, provides high heat input and is easy to regulate.

COURSE OUTLINE:

Introduction to Aluminium welding

  • A basic overview of brazing, providing personnel a better understanding of the joining method they are employing.
