Aluminium Welding :- Follow the rules of thumb offered here for selecting welding equipment, preparing base materials, applying proper technique, and visually inspecting weldments to ensure high-quality gas-metal-and gas tungsten-arc welds on aluminum alloys. Even for those experienced in welding steels, welding aluminum alloys can present quite a challenge. Higher thermal conductivity and low melting point of aluminum alloys can easily lead to burnthrough unless welders follow prescribed procedures. Also, feeding aluminum welding wire during gas-metal-arc-welding (GMAW) presents a challenge because the wire is softer than steel, has a lower column strength, and tends to tangle at the drive roll. To overcome these challenges, operators need to follow the rules of thumb and equipment-selection guidelines.

Some of the best known welding methods include:

Shielded metal arc welding (SMAW) – also known as "stick welding or electric welding", uses an electrode that has flux around it to protect the weld puddle. The electrode holder holds the electrode as it slowly melts away. Slag protects the weld puddle from atmospheric contamination.

Gas tungsten arc welding (GTAW) – also known as TIG (tungsten, inert gas), uses a non-consumable tungsten electrode to produce the weld. The weld area is protected from atmospheric contamination by an inert shielding gas such as argon or helium.

Gas metal arc welding (GMAW) – commonly termed MIG (metal, inert gas), uses a wire feeding gun that feeds wire at an adjustable speed and flows an argon-based shielding gas or a mix of argon and carbon dioxide (CO2) over the weld puddle to protect it from atmospheric contamination.

Flux-cored arc welding (FCAW) – almost identical to MIG welding except it uses a special tubular wire filled with flux; it can be used with or without shielding gas, depending on the filler.

Many people think of welding as just another industrial job, like operating a jackhammer or a fork lift. But modern welding is much more than that. Welding is an art, and a science, and a high-paying career all in one.

modern welding is both an art and a scienceAt its essence, welding is the joining of two materials, usually metals or thermoplastics. This is generally accomplished by melting the two pieces of material to be joined, and adding a filler material to produce a molten pool, known as the weld pool.

Once the welding arc is removed the pool cools, forming a joint between the two workpieces that is both strong and highly durable.
