Spot Welding Stainless Steel & Aluminium Sheet Metal
“Spot welding is a core part of our metal welding capability. Here at JC Metalworks, spot welding is most often used for the speedy fabrication of thin sheets of stainless steel or aluminium.”
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 spot and seam welding, techniques that are widely used in the metal welding and fabrication industry.
Typically, spot welding is used where metal sheets of stainless steel or aluminium are in the 0.5 – 3mm thickness range. The process uses two shaped copper alloy electrodes to concentrate 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 metal sheet.
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 TiG welding capacity.
We have also upgraded the extraction system that runs through each of our metal welding bays, giving our metal welders and fabricators a safe working environment and the facilities they need to carry out the quality work they do each and every day.
Metal Inert Gas (MiG) welding is a welding process in which an electric arc forms between a consumable wire electrode and the workpiece metal(s). This heats the workpiece metal(s) causing them to melt and join.
Originally developed in the 1940s for welding Aluminium and other non-ferrous materials, MiG was soon applied to steels because it provided 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 MiG is the most common industrial welding process, preferred for its versatility and speed.
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 such as Brass. The process gives the operator greater control over the weld than competing processes, allowing for stronger, higher quality welds. TiG welding is comparatively more complex and difficult to master and is slower than most other welding techniques.
Typical examples of products created using spot and seam welding techniques include the manufacture of point of sale units and retail fixtures, HVAC systems, electrical enclosures and metal cabinets, along with lighting systems.
