Looking for a professional welding service?

In reality, most people could pick up a welder and crudely fuse two pieces of metal together, however, to do it precisely, structurally sound and visually appealing is an art that takes years of practice and experience.

Based in The Hills District and Serving the greater Sydney Metropolitan area, Metalmac owner David McNeice left behind a successful professional career sitting behind a computer to pursue his passion as a Welder and Metal Fabricator.

Being able to express his creative side through solving engineering problems and creating effective solutions with his technical know-how is something David finds much more rewarding than his previous employment.

Mobile Onsite Welding

One of our core services at Metalmac is providing a mobile onsite welding service to the greater Sydney metropolitan area. In many cases, this is to service larger industries that have extensive onsite maintenance schedules for both heavy equipment and infrastructure but could also be on the local domestic level services structures such as gates, fences, trailers or anything else made of structural steel.

Types of Welding We Offer

MIG

Metal Inert Gas Welding or metal Active Gas Welding is one of the most commonly used techniques in industrial welding practices as it is relatively fast and efficient when compared to some of the older practices.

A MIG welding torch has a thin wire electrode that feeds from a roll on the machine itself. The speed at which the wire is feed can be controlled by the operator as well as the desired power output, amperage. Also feed from the welding gun is a shielding gas that helps prevent oxidation and makes a better quality weld. Atmospheric gases can cause porosity and fusion defects, so the use of argon, helium, carbon dioxide or a mixture of all 3 is used to mitigate this issue.

The advantages of using the MIG is it is easy to use and surface preparation is not as important when compared to other welding processes. The disadvantages are that it gives up a small amount of control when compared to the TIG.

TIG

Tungsten Inert Gas Welding

Tungsten Inert Gas Welding, sometimes referred to as GTAW (Gas Tungsten arc welding) is commonly used on non-ferrous metals such as copper, magnesium and aluminium, but is also the preferred method of welding thin pieces of stainless steel and other iron-based metals.

The big advantage of TIG welding is greater control over the welding process, giving the operator a better chance at creating stronger and higher quality welds.

The disadvantages are the process is slower which adds more time to a job and this welding technique takes an experienced operator. Learning this method of welding is a complex art that can take a good while for the operator to become proficient in

Stick Welding

Often considered ‘the old way’ of doing things a stick welder is the most basic of welding machines using a stick rod as the electrode, which is also the filler metal that helps to fuse the metals together. There are no protective gases used in stick welding.

Generally, stick or arc welding is still a very good option on heavier structural steels and thicker pieces of metal. When it comes to welding sheet metal or other thin pieces then this is not the best option.

A stick welder is very easy to use and very cheap to purchase.

Plasma Arc Welding (PAW)

The key differences between GTAW and PAW are the electrode is positioned in the body of the torch so the plasma arc is separated from the shielding gas. The gas plasma is then forced through a fine bore copper exit orifice on the torch at high velocities. This high-velocity gas exiting the nozzle is suitable for both welding and cutting purposes not unlike an oxy torch.

The key difference between plasma arc welding and oxy-acetylene welding is the plasma arc is around 28,000 degrees Celcius. By comparison, an oxy-acetylene flame is approximately 3150 degrees Celcius and a normal welding arc is around 10,000 degrees Celcius.

Gas Welding

This is another welding process becoming less and less used as time goes by due to the effectiveness of the TIG. This process usually refers to the use of oxygen and acetylene mixed together in the welding torch and this flame is used to create heat on the job surface. A rod is then applied to the heated joint which then melts to provide the filler metal and the joint strength.
