Aluminum Welding Procedures

Welding aluminumFinding the best aluminum welding procedures is usually challenging based on the procedure utilized and also the size of the aluminum. You will find three general and fundamental welding techniques to weld aluminum; these are Gas, Mig and Tig alloy welding.

Welding Alloys Using Oxy-Acetyleen.

This kind of welding isn’t widespread however, will likely be associated with numerous servicing businesses for example refrigeration repairs. Usually it calls for fusing extremely thin aluminum sheets employing oxy acetylene apparatus with fine welding torch tips.

Aluminum naturally is hard to ascertain the stage when the alloy would actually liquefy. As a result attempting to heat several components of aluminum to join them could lead to the actual aluminum purely ‘dropping out’ once the melting stage is achieved. Oxy acetylene welding aluminum for that reason is really a procedure that can actually just be completed by means of practice until finally natural expertise enables the user recognize if the materials can be near to melting point and whenever filler may be delivered.

Mig Welding Alloy.

This is actually the smart way and the most typical method to weld aluminum. Mig welding utilizes a constant wire feed of aluminum wire put on to the weld area. Mig welding aluminum makes it possible for welding of 1mm thick alloy and up-wards. Dependent upon the amperage power from the Mig welding machine. Thinner aluminum might need to get spot welded to prevent blowing through, once again that is dependent upon the size of your wire electrode being employed, the lesser gauge wire applied the finer any aluminum you’ll be able to operate on. Typically a .09mm welding wire would be capable of welding sheet metals of 1mm up to 2.5mm.

Sheet metals are generally welded making use of mig welders; typical use is on aluminum watercraft building, gates, fencing and lightweight architectural and architectural work. Welding aluminum on hefty gauges is comparable to that of welding metal, here wire size of 1.2mm will be ideal. The easiest of aluminum welding procedures.

When switching a mig welder from steel welding to alloy welding, you will have to customize the welding cable liner to one created from Teflon that will enable easy running with the filler wire. Aluminum wire is much weaker compared with metal and needs much less friction throughout the cable and also gun. Additionally you will probably need to make use of 100 % pure argon gas rather than cO2 found in metal welding migs.

Aluminum Welding Procedures using a Tig welder.

Tig welding aluminum can also be challenging and needs a good amount of training. Comparable in a manner to gas welding it includes heating up the actual aluminum to melting stage utilizing a tig welding torch as well as presenting a filler rod in the appropriate instant to produce a welding bead. Mastering to weld aluminum employing a Tig machine is most fulfilling because the completed job is really a form of artwork. It takes a reasonable level of expertise and will allow your completed weld to get as tiny as 1/16 inches wide.

    I’m most familiar with oxyacetylene welding. Like you said, it’s used a lot for refrigerator repairs. I think it’s neat how you can usually tell what kind of welding was used by the weld.
