Aluminum gas welding can be accomplished with gas tungsten arc welding (GTAW) and it can also be used to weld steel, as well as other metals. GTAW is also called tungsten inert gas (TIG) welding. Welding steel is one of the easier jobs when using rig welding, but there are a number of factors, which make it much harder to weld aluminum.

From cleanliness, arc length, machine settings, welding with a dirty tungsten electrode, filler rod angle, type of electrode, torch angle and size of electrode – you have to be extra-careful with all of these factors when you tig weld aluminum.

Here we go over these factors and how you have to be much more careful with aluminum than with steel.

- Make sure that the settings for your machine are correct. Set your machine to use alternating current and the high frequency switch should be at continuous mode otherwise it will make the arc stutter.

- A piece or object of aluminum left outside is likely to be highly oxidized after having come in contact with the elements. That should be weld only after thoroughly cleaning it – otherwise it will burn or weld extremely fast.

- Arc length – it is important to keep the arc at just the correct length. Arc lengths too long or too short, both should be avoided with aluminum. Too short the length, you your metal will jump on your electrode, damaging that and you. Too long a length and the heat will not be pinpointed enough to be of proper use.

- Keep your electrode clean. A dirty electrode will make the weld sooty – taking any fun out of the job you may have been having.

- Do not use pure tungsten electrodes with the new types of tig inverters to weld aluminum. The old types could use them, but not these new ones.

- You should keep the 1/16″, 3/32″ and 1/8″ sized tungsten electrodes within easy reach when working with aluminum. With steel it is one size fits all policy, where you can go with a 3/32″ tungsten for most of the jobs. But with aluminum, you need different electrodes depending on the thickness of the aluminum.

Aluminum gas welding just needs to be done with more care than other types of welding. Keep all these factors in mind and you will have your aluminum boat repaired or your ladder fixed in the best possible manner.

This is what we are going to discuss. It is a known fact that Welding is a sculptural process that joins two metals by the process of welding and Weldor is a man who does the welding process. Compared to other industrial jobs, welding is fairly dangerous and the occupational and health hazards of welding can be avoided with proper equipment, safe materials, and a few common sense measures. Welding tools and welding equipment are essential in welding services and the manufacturing industries fail to meet the demands, if there are no proper welding tools and welding products.

The process of welding was there from 310 AD itself and the first welding process introduced was forge welding, and later on many welding processes were introduced to weld different types of metals. From the decade, welding has developed a lot and new welding technologies with advanced welding equipment and systems have been introduced. Historical monuments, construction of building, bridges, ship building, automobile, aerospace, power plants, refineries and all manufacturing activities need the process of welding. 20th century started good for the welding process because it saw many new welding processes and technologies.

Stick welding, tig welding and mig welding are the welding process that is used frequently in welding industries. All these welding equipment needs the appropriate welder machines and the welder machine is an equipment that is used to make weld. The arc welding process is categorized into two types depends upon the usage of its consumables. The mig welding comes under the consumable electrode method whereas tig welding comes under the non consumable electrode method. The tig welding use the tungsten electrode as its consumables and by using this process, steel, aluminum, magnesium and copper alloys are welded.

Stick welding method is primarily used to weld iron and steels. Mig welding process is originally developed to weld aluminum, but later on it is used to weld steels. Different types of welder machines are available such as mig welder, tig welder, on board welder, reconditioned welder, aluminum welder, steel welder and metal welder can be used for the process of welding. Consumables available for welding are tig consumables, mig consumables, plasma cutter consumables, tungsten consumables and welding accessories are the tools that are attached to welding machines, and it is used for the better performance of welding.

Modernization is what most of the welding products is, on roll capacity of wires, extended wires, portability and compatibility is its features. These welders machine can be typically used in all industrial applications from light fabrication to aerospace. Welding accessories such as foot pedal, air regulator, ground clamp and argon regulator are essential to support the welder machines. For the weldor’s safety, each and every industries should be equipped with welding gears such as welding helmets, welding clothes welding goggles and welding gloves for the safety of the weldor.

The manufacturing industries should be aware of all the welding tools and welding equipment for the better development of their industries.

Welding is a sculptural process where it deals with raw items such as metal and pipes Historical monuments, construction of building, bridges, ship building, automobile, aerospace, power plants, refineries and lots of manufacturing activities needs the process of welding and it is a part of it. The manufacturing industry came to know about the importance of welding service during 20th century and new welding equipment with latest welding technology were introduced later and requirement for welding supplies increased a lot. The welding industry should be equipped with modern tools such as welding electrodes, welding torches, welding consumables and welding guns and should follow the proper welding system with appropriate welding technology.

There are different types of welding process and each one has its own merits and demerits. Arc welding is a welding technique that uses a welding power supply and creates electric arc between electrode and base materials and Forge welding is a process that joins metal by heating them to high temperature. Tig welding uses tungsten electrode to produce the weld and it is the other name for gas tungsten metal arc welding and it is used to weld thin sections of stainless steel and non ferrous metals. Mig welding is an automatic arc welding process preferred for its versatility and speed and weld aluminum and non ferrous materials. Spot welding is a process in which metal surfaces are joined by the heat obtained from resistance of current flow. Gas welding is also called as oxy-fuel welding and use gases to weld and cut metals. Stick welding or shielded metal arc welding is a manual arc welding process that uses consumable electrodes. Plasma arc welding uses plasma gas and has narrow penetration with greater energy concentration.

Plasma arc cutting is an easy process if you follow these safety precautions. Do not touch any wet surface when operating the plasma cutter equipment and don’t use plasma cutters without any proper protection. Don’t remove the ground cable, which is attached with the work object and ensure that there is proper earth since it connects with high electric circuit. In welding, electrode is used to conduct current and it is of two types such as consumable one and a non consumable one. Shielded metal arc, gas metal arc, flux cored arc and submerged arc welding comes under the category of consumable electrode methods and tig welding and plasma arc welding are non consumable electrode methods

Apart from the welding products such as mig, tig, stick and submerged arc welding products, the other products such as wire feeders, spot welders, multi process units and water coolers comes under the welding products. Welding equipment is a heat generating equipment and it is needed to be cooled by some machines. Water coolers are the instruments which prevent overheating of machines. These have the motors which create a flow of water and cool the welding equipment. Tungsten electrodes are used in tungsten arc welding process. Tungsten electrode is used to weld stainless steel and non ferrous metals and it is called as a steel electrode.

Compared to welding other metals, welding aluminum is easier because of various factors, among them the propensity of aluminum to thaw out at a comparatively lower temperature and not breaking when it turns rock-solid. Depending on the type of alloy of aluminum you are using, you will weld the metal differently. With a little effort you can learn how to weld aluminum in all its different forms.

The various types of alloys include non-heat-treatable alloys like the ones containing manganese (Mn) and Magnesium (Mg) and heat-treatable alloys containing magnesium zinc and silicon copper.

Work pieces made from these types of aluminum are easier to weld whereas the ones containing copper and lead are harder to work with. Copper and lead alloys usually have a tendency to crack when they are weld, which makes it harder to work with them.

Different Welding Methods – MIG and TIG Welding

Apart from gas and plasma welding, the two most often used welding methods are TIG welding and MIG welding. Tungsten inert gas (TIG) welding, also known as Gas tungsten arc welding (GTAW) uses non-consumable tungsten electrode to produce the weld. The power is a constant current welding power supply.

MIG welding process is a subtype of gas metal arc welding. Among the two, MIG welding is the more advanced and can handle thicker aluminum work pieces, at a much faster speed.

Safety, Precautions and First Aid

Safety for yourself and your environment should always be your primary concern when welding aluminum, or any other metal. Welding is unlike many other hobbies or jobs because of the high temperature and stress that are involved in it. Apart from the high temperature, flames, the arc and molten metal are constant risk. Keeping this in mind, wearing your helmet and glasses while you work cannot be compromised with. It must be a habit with you to flick the glass down when you start welding.

Aluminum also requires special care because aluminum jobs produce imperfections in the weld area that have to be brushed away with a steel brush from time to time. You have to be careful while you use the brush.

It is also advisable to learn how to aluminum weld properly as well as know basic first aid in case you or any of your coworkers are injured while welding. Without adequate safety and precaution, your aluminum welding job is an endeavor fraught with risk. You must take steps outlined here to reduce that risk.

The TIG welding process allows a welder exacts controls which result in a clean weld blob. TIG welding machines are frequently used to weld stainless steel, aluminum, magnesium, copper, brass, chrome and other alloys.

The acronym TIG stands for tungsten inert gas; though, the official name for the progression is GTAW. A type of arc welding, TIG uses a tungsten electrode held in a TIG torch. Shielding gases flow from around the tip of the torch to stop weld corrosion. The tungsten electrode is not consumed by the weld; it simply serves as a means of directing the arc. A separate filler rod adds metal to the weld. The welder uses one hand to hold the TIG torch, one hand to hold the filler rod and a foot control to operate the heat input to the weld.

Most stick welding machines can be converted into TIG machines through the addition of an air cooled TIG torch, TIG machines provide additional features that allow for wider welding applications. High frequency start features produce an arc without a physical strike. Preflow and post flow a characteristic start the stream of shielding gas before and extends it after the actual welding. Particular frequency settings manage the welding arc for welding different types of metal, including aluminum.

Operated By Only Whoever Is Skilled Welder

A TIG welder can weld any type of metal. Specialized welders are required for TIG purpose because skill required is high. TIG welds are of the highest quality when compared to stick welders. Stick welders can weld steel where medium skill is required. Stick welding is used for rugged outside conditions and repair shops. TIG welders are used in more refined conditions and applications.

TIG welders require less current and pleasing weld appearance. A tungsten electrode is used to carry the arc from the torch to the work piece. Filler metals require separate electrode that is fed manually. The gas is used for shielding.

Most of the packages have work cable, clamp, input power cord, TIG torch, gas regulator with hose and foot control. Shielding gas is also required but it is sold independently. For safety purpose, individual protective gear, especially gloves, shields and eyeglasses should be worn to shield the welder.

It Will Let You Get Extraordinary Benefits

TIG welding machines produce high quality welds through precise control of the heat input through a foot petal feature. Smaller amounts of filler metal is added to the weld puddle, creating vary little spattering or sparking. The welding process does not generate slag, saving the welder from having to remove slag among weld passes. TIG allows welders to produce welds in a variety of positions: flat, straight up and overhead.
