Sheet Metal Welding

The welding of stainless steel and aluminium are areas of particular skill at Stevens Rowsell and we supply into market sectors and businesses that require tight tolerances and extremely high visual standard with no ‘inclusions’ or porosity. Welding of sheet metal, especially aluminium welding and stainless steel welding, requires a high degree of skill and dexterity to produce clean, neat and visually appealing welds consistently and to drawing specification. When the job demands greater control, reliability and flexibility you need to employ the correct welding technology to ensure you achieve the desired results. This is why we only use high performance welding sets made by either Miller or Murex / ESAB.

We have a range of welding technologies and welding sets to suit a wide variety of production requirements as different jobs require different technologies.

It’s all very well having skilled welders and the best welding sets but if you do not use top quality consumables and accessories from reliable and accredited sources then you run the risk of compromising the quality of your work which is why we do not use cheaper imported wires and torches.

We can weld a variety of metals up to the thickness that we can cut and process on our lasers;

We undertake various types of welding within our manufacturing operation namely;

MIG Welding

Metal Inert Gas welding, predominantly known as MIG is a commonly used high deposition rate welding process.
Metal wire is continuously fed from a spool over the pieces of metal being joined together as a high frequency electrical current is fed to it. An electric arc is formed when this electric current passes between the metal wire and the metal to be welded. The resultant heat of the arc melts the metal away and forms a molten pool which subsequently cools, fusing the metals together leaving a strong welded join.

We use MIG welding for fusing mild steels together where they are not overlapping or where the materials are too thick to be spot welded. This process is beneficial where minimal post weld cleaning is required, when long welds need to be made without start stopping or where the weld needs to be applied quickly.

Final TIG welding process

We use Tungsten Inert Gas welding, commonly called TIG welding, for all of our stainless steel and aluminium components and for thin gauge mild steel. The TIG process is slower than MIG and produces a more precise and superior quality finish. It enables us to weld intricate detail on smaller componentry where precision and aesthetics are of vital importance. TIG can be used at lower amperages for very thin and soft exotic metals where heat and distortion must be kept to a minimum. Welds are generally made without filler metal and are free from splatter giving a clean professional looking end product.

Resistance Welding

Resistance Spot Welding (RSW) is a commonly used resistance welding process that uses the application of electric current and mechanical pressure to create a weld between two pieces of metal. Weld electrodes conduct the electric current to the two pieces of metal as they are forged together under sufficient heat and mechanical pressure to create a molten state and a resultant strong join. This process is easily automated, can be done at high speed and is very economical.
