Aluminum Welders

Aluminum alloys are often chosen because of their high strength-to-weight ratio, corrosion resistance, low cost, high thermal, and electrical conductivity. There are a variety of techniques for joining aluminum, including mechanical fasteners, welding, gluing, brazing and soldering, and so on. Different methods are used depending on the cost and strength required for assembly. Also, process combinations can be performed to provide assembly means that are difficult to assemble and reduce certain process limitations. Aluminum Welders

Most aluminum alloys can be welded together. However, some aircraft grade aluminum and other special alloys are not weldable by conventional methods. Aluminum is generally welded with gas stream arc welding (GMAW) and tungsten gas arc welding (GTAW). Due to the aluminum oxide layer, a positive polarity is required to break the surface to ensure a proper seal. AC (Alternating Current) is also used to provide the advantages of a negative polarity that provides sufficient penetration and positive polarity for a non-containment weld. For more details on welding parameters, structural welding codes for aluminum are available in AWS Welding aluminum generally creates a softened area in the molten metal and the heat affected area. Additional heat treatments may be required to obtain an acceptable material for an application. Industrial welding is also commonly used in aluminum assembly: friction stir welding, laser welding, and ultrasonic welding are some of the many processes used.

Aluminum can be brazed or brazed on almost any material, including concrete, ceramics, and wood. Brazing and brazing can be applied manually or by automated technique. Manual brazing with aluminum can be difficult due to the lack of visible color change before melting. Similar to other procedures, durable aluminum oxide can prevent proper bonding. Strong acids and bases can be used to weaken the oxide, or aggressive fluxes can be used. Brazing alloys for aluminum must have a relatively low melting temperature, lower than the aluminum melting point (660 ° C). Also, magnesium-rich aluminum alloys can “poison” fluxes and lower the melting temperature, which can lead to seal weakness.

In some cases, the aluminum parts may be coated with different material and brazed with a more common filling technique and equipment. Brazed joints require overlapping parts. The amount of overlap can significantly affect the strength of the joint.Aluminum Welders
