MIG Welding Aluminium & Light Steel
Here at JC Metalworks, we employ a highly-skilled and experienced team of metal welders and fabricators with the skills and capability to carry out metal inert gas welding in large quantities. It is a technique which is widely used in the metal welding and fabrication industry on aluminium and light steel and is commonly referred to as MiG welding.
Metal inert gas welding is a welding process in which an electric arc forms between a consumable MiG welding wire electrode and the workpiece metal(s). This heats the workpiece metal(s) causing them to melt and join. Metal inert gas welding is a process by which almost any metal can be welded. It is a quick, cost effective method and the results are more than acceptable for the majority of manufacturing and fabrication requirements.
Originally developed in the 1940s for welding aluminium and other non-ferrous materials, MiG welding was soon applied to light steel because it delivered a faster welding time compared to other welding processes. Further developments in the 1950s and 1960s gave the process more versatility and as a result it became highly used in industrial processes. Today it is the most common industrial welding and fabrication process, preferred for its versatility and speed.
You’ll be pleased to hear that we have recently carried out and completed a programme of investment and improvement within our welding bay area which has resulted in an increase of 20% to our MiG welding capacity.
We have also upgraded the extraction system that runs through each of our metal welding bays, giving our welders a safe working environment and the facilities they need to carry out the quality work they do each and every day.
MiG Welding Aluminium or Stainless Steel? Read about TiG Welding
TiG welding is an arc welding process that uses a non-consumable tungsten electrode to produce the weld. TiG welding is most commonly used to weld thin sections of stainless steel and non-ferrous metals such as Aluminium, Magnesium and Copper alloys. The process gives the operator greater control over the weld than competing processes, which allows for stronger, higher quality welds. TiG welding is comparatively more complex and difficult to master and is slower than most other welding techniques.
Welding Metal Thinner Than 3mm? Read about Spot Welding
Typically, Spot welding is used where the sheets are in the 0.5 – 3mm thickness range. The process uses two shaped copper alloy electrodes to concentrate the welding current into a small ‘spot’ and to simultaneously clamp the sheets together. Forcing a large current through the ‘spot’ will melt the metal and form the weld. The attractive feature of spot welding is that a lot of energy can be delivered to the spot in a very short time (10 – 100 milliseconds). This allows the welding to occur without excessive heating to the remainder of the sheet.
Our team of precision fabricators also offer TIG welding, which is often used on stainless steel and aluminium. TIG welding also requires a specialised welder.
Finally, our fabricators are able to offer spot welding, which is used for materials thinner than 3mm and when large flat non-visible areas of metal need to be welded together.
Typical examples of products that are created by MiG welding aluminium and light steel include the manufacture of point of sale units and retail fixtures, HVAC systems, electrical enclosures and metal cabinets, along with lighting systems.
What are the Different Types of Welding Used in Metal Fabrication?
Metal fabrication is the process wherein metal parts are welded, as well as finished and dressed, to prepare for the finishing process. But what are the different types of welding used in metal fabrication?
