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.

TIG Welders – Lightweight Welding Power

tig weldersTIG welders are commonly available as a Tig AC/DC power source that allows manual electrode welding as well as TIG welding. Modern machines contain microprocessors that give full digital control that results in perfect tig welds. TIG welders of this nature are rated from around 170 A to 300A, they are lightweight, portable and excellent welding machines suited for construction and maintenance work.

Larger TIG welders will run from 400 to 500A output. Machines of this nature also fully digital controlled. Applications include plant construction, aerospace and shipbuilding, pipeline construction and installations

When TIG welding, the operator has more control over the whole process of welding. Unlike other welding types Tig welders use tungsten electrodes that are non consumable. Tungsten is used as the melting point is extremely high, allowing the operator to introduce a filler rod to the weld. Many in the welding industry use tig welders to weld non ferrous metals such as magnesium, copper, and aluminum as well as stainless steel.

The Advantages of TIG Welders

The electrodes used with TIG welding are non-consumable, while other types of welding, like tig welderarc and mig welding use electrodes that are consumable. There are advantages with both methods but with TIG welders there is no need to stop in the middle of a project and replace the rod that has been used up. As one might expect, stopping at a critical point can cause an imperfection in the quality of the finished product. With the undisturbed work that can be done with the TIG system, the overall quality is much better.

TIG welders are a good choice when working with non-ferrous metals like copper, magnesium, and aluminum.

Minor disadvantages of TIG Welders

If you have ever wondered why there are so many different welding techniques as well as equipment, the answer is simply that there are different situations that require welding of a different kind using an array of different equipment. For this reason tig welding is a somewhat specialized feild.

For one thing, TIG welding is more complicated and requires more skill and better training in order to carry it off right. The welder using a TIG welding machine must have much greater accuracy and control in directing the tig torch and using the filler rods. Maintaining the arc in the correct position and the right distance from the piece they are working on is critical.

Welding with a tig machine is more time consuming than most of the other methods, but you must remember that this time means the finished work will be much higher quality, making it worth the time it takes to complete. Wearing a quality welding helmet is essential as the arc created from tig welders is much brighter than conventional welders.
