MIG welding is a kind of arc welding that uses a metal electrode to match the alloy of the work section and an inert gas to transfer oxygen from the weld region. MIG welding is the most suitable welding technique for aluminum, with the exception of particularly thin aluminum sheeting.

MIG welding is a kind of arc welding that uses a metal electrode to match the alloy of the work section and an inert gas to transfer oxygen from the weld region. MIG welding is the most suitable welding technique for aluminum, with the exception of particularly thin aluminum sheeting. MIG welding aluminum needs more practice and skill than welding steel.

Prepare the surfaces of the aluminum elements by cleaning the exterior with a solvent, then using the wire brush to remove any oxides. This removes any constituent part and impurities and prevents them from becoming trapped in the weld.

Clutch the electrode at a 10- to 15-degree angle from the vertical, sharp toward the way of the ppr pipe cutter . It is significant to use the push process when MIG welding aluminum. The pull process would prevent the argon gas from sufficiently covering the weld, resulting in an inconsistent weld.

Make a pool of molten aluminum with the electrode and gradually push the electrode forward. Regulate the voltage of the welding machine to get spray transfer of the aluminum electrode. In spray transfer, the electrode release small droplets of the metal into the weld. This will results in a smooth weld and the droplets do not get in the way with the electrode arc.

Oxy-Acetylene Welding Equipment

Welding with the use of gas dates back to the middle of 1800's where the mixture of oxygen and hydrogen were used in the making of jewelery.

Today we use a different mixture of oxygen and acetylene which together can produce a flame temperature in excess of 6000 deg f. This type of equipment is not only used for welding, but also to heat materials for bending and straightening, brazing and cutting.

An oxy-acetylene outfit is usually portable, versatile, and less expensive than a electric welding set up, and by using the correct tips, rods and fluxes, almost any metal can be welded, heated or cut. This equipment is ideally suited to the welding of thin sheets, tubes and pipes but not economical for thick section welds.

Arc Welders

Arc welding or stick Ppr pipe welding machine requires a higher skill level and mastery of certain techniques. Best for welding on thicker, rougher metals using a flux coated stick electrode fusing the work pieces together.

To avoid porosity and attain the ideal weld travel speed, it is important to remove excessive scale, rust, moisture, paint, oil and grease from the surface of joints. A variety of electrodes are available for the different types of metal that is to be welded, cast iron, stainless steel etc.

The electrodes need to be replaced as the heat builds up and the stick melts down causing a molten weld puddle on the work piece fusing the work pieces together. The weld must be cleaned when completed due to the flux electrode forming a slag blanket over the weld bead. Using an arc welder is a relatively slow process and is ideal for the more experienced user.

MIG Welding

MIG welding is generally a lot easier than gas or arc welding. A spool of weld wire is constantly driven by a feeding system through the MIG gun as the trigger is pulled, so unlike arc welding there is no need to constantly replace electrodes.

One of the best tools for cutting metal is a plasma cutter. It is effective and convenient to use, and thanks to the latest technology being applied in the area, it is now possible to cut metal with almost laser precision.

A plasma cutter works differently than a conventional welding torch. Rather than using a flame produced from a buing gas in the style of oxy acetylene welding, a plasma cutter uses a jet of inert gas such as compressed air, and then applies a very high voltage charge. The electric charge arcs through the jet of air, and ionizes the gas. The ionized gas reaches extremely high temperature, and becomes what is called plasma.

For small jobs in a workshop where metal is being cut in order to make a bodywork patch, or a replacement panel, plasma cutters are the ideal solution. One of the most important aspects of plasma cutters is that they use an inert gas, meaning that you do not have to worry about storing volatile and explosive gases.

In the past, plasma cutters were a fairly imprecise and blunt means of cutting metal thanks to their large "flame", however, thanks to advances in the materials and technology used to manufacture plasma cutters, they are now able to produce a much more focused flame. This means that you not only get a more exact and neater cut, but are able to do it with lower power.

With a basic compressor driven plasma Ppr pipe welding machine , you get a torch with two settings. The pilot arc of plasma is ideal for buing off paint, while when you tu up the power; the cutter is able to cut through sheets of steel an eighth of an inch thick at a rate of around nine inches per minute.

By spending a little more, it is possible to get a more powerful and flexible tool. For less than $1350, you can buy a Lincoln Electric Welders Century 25 Amp Plasma Cutter. This tool is designed for effective auto body repair jobs, and provides a fully earthed cutting arc that removes the high frequency harmonics that are able to damage the complex electronics in a car.

Gas welding is a process in which a fuel gas such as acetylene, hydrogen, natural gas, etc. is mixed with oxygen in proper proportion to bu to get a flame which, if found adequate for melting a given metal, can be used for fusing and joining different parts of it. The process is very versatile because it can weld most of the commonly employed engineering metals and their alloys. Brief description of the well known variants in this class of welding processes follows.

Oxy-Acetylene Welding

This is the best known gas welding process and was successfully employed first time in 1903 when a welding torch for the purpose was developed. In this process acetylene (C2H2) is mixed with oxygen in the welding torch and is then but at the torch tip to give a flame with a temperature of about 3300oC which can melt most of the ferrous and non-ferrous metals in common use.

Oxygen and acetylene are easily available in cylinders at temperature of about 1500 N/cm2 and 170 N/cm2 respectively. These are connected to the welding torch through hoses and are mixed and but to get different types of flames viz., neutral, oxidizing and carburising. The natural of the flame depends upon the ratio of the two gases. The neutral flame is most often used for the welding of most of the materials like low carbon steels, cast steel, cast iron, etc. The oxidising flame has higher proportion of oxygen than acetylene and is used for welding of manganese steel, brass and bronze whereas the carburising flame has higher proportion of acetylene in it and is used for welding aluminium, nickel, etc.plastic pipe cutter

It is quite common to use filler material with gas welding through if need be, the process can be used without filler as well. Commercially, oxy-acetylene process is very widely used for welding of ferrous and non ferrous metals particularly for welding thin sections upto 6 mm. A large percent of the repair work is also done by oxy-acetylene welding.

Typical applications of the process include welding of root run in pipe and other multi-run welds,, light fabrications like ventilation and air-conditioning ducts and motor vehicle repairs.

Oxy-Acetylene Pressure Welding

In normal or non-pressure oxy-acetylene welding process no use of pressure is made to accomplish a joint. However, in slight variant of the usual process, the prices to be joined are heated by oxy-acetylene flame buer and brought to the pasty or semi-solid state. Axial pressure is then applied to achieve a joint which is normally of an upset weld type. No melting of the parts being welded is involved hence it is a solid-state welding process and is also called 'Hot Pressure Welding' or simply as 'Gas Pressure welding'.

The ends of the work piece to be welded are prepared by cutting and cleaning. The pieces are then held in clamps under an axial pressure of about 3.5 to 7.0 n/mm2 for mild steel. An oxy-acetylene torch or a heating head of the desired configuration is made to surround the abutting (or projecting) ends and heated uniformly to about 1200oC. During the heating cycle the pressure is increased to the desired lengths of the two pieces. This is also prevents the possibility of local overheating or superficial melting.

According to a latest survey, most of the fabricators said that welding is one of the most sought after skills in metal fabrication. It is a great art or process that is commonly used for joining materials, usually thermoplastics or metals. Presently, there are so many metal fabricators that offer professional services to all the people.
