Aluminum and its alloys are highly susceptible to deformation during welding due to their high thermal conductivity, large coefficient of thermal expansion, and surface oxide film. Controlling aluminum welding deformation requires a systematic approach.
The following are twelve key steps to reduce aluminum welding deformation, covering the entire process from design and preparation to welding techniques and post-weld treatment:
【ARCFORT University】Key factors in selecting aluminum alloy welding materials
Selecting the right aluminum filler metal (welding wire) is a highly technical task, directly impacting the strength, corrosion resistance, crack resistance, and appearance of the weld joint. The following six key factors will systematically guide you in making the right choice.
【ARCFORT University】Post-weld heat treatment of aluminum alloy welding materials
Heat treatment of aluminum alloys after welding is a critical step in controlling their ultimate properties (strength, toughness, and corrosion resistance). Unlike steel, heat treatment of aluminum alloys has its own unique principles and processes.
【ARCFORT University】Selection of shielding gas for aluminum welding
Choosing the right shielding gas for aluminum welding is crucial for achieving high-quality welds. Below, I’ll explain in detail how to choose the right shielding gas, including the characteristics of different gases, applicable scenarios, and the selection process.
