Robotic welding for aluminum welding process
The inert gas shielded welding (TIG or MIG) method is the most widely used aluminum and aluminum alloy welding method. Aluminum and aluminum alloy sheets can be tungsten - arc argon arc welding or tungsten - pole argon arc welding. Aluminum and aluminum alloy thick plates can be tungsten arc welding, argon - helium mixed tungsten gas shielded welding, gas metal arc welding, pulse gas metal arc welding. MIG welding and pulsed gas metal arc welding are used more and more widely (argon or argon / helium mixed gas).
Robotic welding for aluminum common problem
1. Aluminum alloy welded joints have severe softening and low strength coefficient, which is also the biggest obstacle to the application of aluminum alloys;
2. The surface of the aluminum alloy is prone to refractory oxide film (Al2O3 has a melting point of 2060 °C), which requires a high power density welding process;
3. Aluminum alloy welding is easy to produce pores;
4. Aluminum alloy welding is prone to hot cracks;
5. Linear expansion coefficient is large, easy to produce welding deformation;
6. Aluminum alloy has a high thermal conductivity (about 4 times that of steel). At the same welding speed, the heat input is 2 to 4 times larger than that of welded steel.
Therefore, the welding of aluminum alloy requires an efficient welding method with high energy density, small welding heat input, and high welding speed.
