Why choose Radshape for Metal Welding?

Our ability to work with a range of materials including mild steel, aluminium, stainless steel and brass, combined with the fact that we handle projects from beginning to end if need be, means that we can take on whatever requirements our clients come to us with.

Our purpose-built facility is equally able to handle Free Issue components and welding which forms part of full production, and we can handle everything from the smallest bracket to large-scale fabrications and assemblies.

The facilities that we offer our clients are a prime example of our commitment to flexibility, excellence and continuous improvement. Whether they come to us needing intricate fine work on components that will be highly visible or are extremely safety critical, coded welders or heavy welding on larger structures such as the chassis of a motor vehicle, clients can be sure that we’ll have just the right combination of high-tech equipment and experienced technicians needed to deliver their requirements in full.

What is meant by Welding?

Welding is the process of joining metal parts through the application of heat, pressure, and filler metal. Metal Welding can be done manually with an oxy-acetylene torch or C02 laser, but the most common welding practice is arc welding. In this process, electricity is used to produce heat that melts the metals that are being joined together.

Welding metal together usually produces a joint that has greater strength than the original metal from which the part was made. This can be used to join metals or non-metals, depending on the filler metal used, and is done in various industries such as construction, automotive repair, shipbuilding, aircraft maintenance, commercial fishing industry and equipment repair.

Metal Welding can be carried out on steel, cast iron, malleable iron, copper alloys, aluminium, brass or bronze, but the material must be strong enough to endure the heat and pressure of welding.

What are the types of Welding?

There are many different types of welding methods that we at Radshape can offer, including MIG Welding, TIG Welding, ARC Welding, Spot Welding (Projection), Brazing and Soldering.

Welders often use one or more of these different methods to weld various materials together.
MIG is most often used for welding mild steel and aluminium.
TIG most often weld stainless steel and exotic metals.

Spot / Projection Welding is used to do precise work. Welders can choose to weld by using the Oxy-Acetylene method or with an electric arc.
However, the use of the Oxy-Acetylene method is often referred to as Cutting instead of Welding.

MIG Welding

The MIG welding process, which stands for Metal InertGas Welding, is one of the most common ways to weld. MIG Welders use a continuous wire feed and produce a strength that is suitable for structural steel projects.

Welders can adjust the voltage and wire-feed speed settings in order to increase or decrease penetration into the base material and control heat input during Welding. MIG Welding is typically used in order to weld different types of metals together including steel, stainless steel and aluminium.

TIG Welding

The TIG welding process, which stands for Tungsten Inert Gas Welding, is another very common Welding method. TIG Welders use a non-consumable tungsten electrode to produce the Welding arc and molten metal.

Welders control the voltage, gas shielding and wire-feed speed settings in order to achieve desired Welds such as penetration and bead shape and size. Welders typically use TIG Weld with either pure argon gas or a mixture of helium and argon in order to Weld steel, stainless steel and aluminium.

Spot / Projection Welding

The Spot/Projection welding process is used to Weld two pieces of metal together. Welding electrodes are used with sharp points or welding guns to create the Weld spot on the base material.

Welders then bring the projection into contact with the base material that they are trying to Weld together and press the trigger on the electrode.

ARC Welding

The ARC welding process welds two pieces of metal together using a Welding gun that produces an electric arc between a bare Welding electrode and the base material.

This method of gas welding is used in order to control the flame from the power source.


Soldering also joins two metal pieces together by melting a soft, low-melting-point metal filler into a joint.

Welders use this method with copper or lead-based filler materials in order to Weld together different types of metals including steel, copper and aluminium.

Oxy-Acetylene Welding

Oxy-Acetylene Welding is another common Welding method that uses an oxy-acetylene flame to heat base material until it becomes molten enough to Weld together. Welders use this Welding method to Weld together different types of metals including steel, copper and aluminium.

Welders can choose to Weld using a flux-coated rod instead of Welding with the molten metal produced by this method. Welders often refer to themselves as Cutters when they are doing work using an oxy-acetylene flame.

What is the strongest type of weld to use?

The strongest type of weld to use is a TIG Weld. This type of weld has been proven to have a solid bond that can handle the most pressure from weight and from tension.

The TIG Welding process will require a special machine that can control the amount of heat that is being transferred.
