Metalwork – The Pros and Cons of Different Welding Processes

Welders around the world are employed in various industries, and they use their metalwork experience to build skyscrapers, space vehicles, bridges, cars and much more! Many different kinds of welds can be made with unique processes and in a typical welder’s toolbox, you will find a speed square, needle scaler, grinder and chop saw. It’s not just the tools a welder will need to get the job done though, because he or she must be skilled in the following weld types.
Submerged Arc Welding (SAW)

If you need to weld thick sections of metal then contact a metalwork specialist for Submerged Arc Welding (SAW). This process offers high metal deposition rates, and is ideal for use with alloy steels, low alloy and carbon. Arc visibility and welding fume radiation is low, resulting in high-quality welds. Just like with any other type of welding process there are some cons, such as the fact that SAW can only be completed on flat or horizontal surfaces, and the correct electrode alignment must be preserved with a lot of care and attention, making it a somewhat time-consuming task.

Shielded Metal Arc Welding (SMAW)
Do you want to get metalwork services completed on a large piece of material that is based in a remote location? If so, opt for Shielded Metal Arc Welding (SMAW). Simple to master, SMAW requires the use of portable equipment. The cost for SMAW is not too high, and this is why it is a preferred choice for lots of electrodes and applications. One of the great things about this technique is that it is suitable for out-of-position welding, but there tends to be a great deal of metal wastage and electrodes must be changed regularly, resulting in frequent stops and starts.

Gas Tungsten Arc Welding (GTAW)
When you get in touch with a professional for flat or horizontal welding solutions, he or she will probably recommend Gas Tungsten Arc Welding (GTAW). High in quality and appearance, GTAW welds can be completed on a broad scope of materials, such as stainless steel, copper alloys, magnesium and aluminium. Welds are produced with a non-consumable`tungsten electrode, and filler metal is sometimes used to protect the material. Plasma Arc Welding is a similar welding technique that uses an alternatively type of welding torch.

What type of metalwork do you need done? Fabricating, welding, laser cutting – all of these services and more are available from SAMS Fabrications. Call 07786214039 for a quote.
