When welding aluminum, experience is a great asset. It is also very important to have a solid hand for precision machining of aluminum. How to weld aluminum strips and what is required for this is explained here.
A feature related to aluminum welding is the high thermal conductivity of the metal. It is much higher than that of other metals. Due to the increased conductivity, heat spreads rapidly and this can lead to high stresses inside the workpiece. An uncontrolled delay occurs when the wrong welding technology is used and the equipment is not suitable for this.
Aluminum does not discolor during welding and therefore it is difficult to visually determine when the melting point has been reached. Only with the acquired experience, you can quickly and efficiently carry out welding work. Various products can be welded: aluminum sheets, aluminum pipes and electrical aluminum tires. https://metromet.ru
Welding TIG for aluminum welding
Tungsten inert gas welders or tungsten inert gas (TIG) welders are well suited for welding aluminum. Advantage of aluminum welding with TIG welding machines:
• very little splashing,
• minimal impact on human health
• welded seams have a stable and high quality.
Occupational safety requirement: always wear a protective suit and mask to protect the respiratory system and the whole body from gases, vapors, smoke and small particles. Always ensure adequate ventilation in the workplace.
You will also need professional equipment and tools for welding aluminum:
• the most important thing is to choose the right welding machine
• welding consumables and accessories for aluminum:
• fire resistant gloves
• aluminum welding wire
• welding helmet
• fire retardant outerwear
• stainless steel brush, sander, sanding paper and file
In addition to the materials mentioned, you will need water and acetone for cleaning, screw clamps for fixing the workpiece and an inert gas for the workflow.
Manual: How does TIG welding work?
In TIG welding, the weld is shielded with an inert gas. As a shielding gas argon or helium is questionable. Helium is more expensive but has a higher thermal conductivity. A mixture of argon and helium is ideal. The inert gas is passed through the nozzle directly to the weld. With an aluminum welding rod, the parts can be neatly joined together. It is important to work accurately and cleanly because dirt or
