Plasma arc welding involves joining metals together by heating with a constricted arc between the workpiece (transfer arc) and an electrode (non-transfer arc) OR the constricting nozzle and the electrode.The constricted plasma that is formed is highly ionised and concentrated. In simple terms, plasma arc welding uses plasma (gas) that has been superheated to become… Continue reading What Are The Advantages and Disadvantages of Plasma Welding?
A lap joint is one of the five different types of welding joints. It is most commonly used when joining two different metals that have different levels of thickness. The ‘lap’ reflects the overlapping pattern that is formed when the two metals are joined together. The thickness of the two metals is what determines the… Continue reading What is a Lap Joint Weld?
If you’ve read our blog on The Science Of Cold Welding, you should have a good understanding of what it is. For those of you who haven’t read it, go take a look for a more detailed explanation of what cold welding is and what it is used for! Whilst cold welding may not be… Continue reading Advantages and Disadvantages of Cold Welding
The welding profession is one that brings a higher risk of injury compared to others. This is why it is extremely important for workers to ensure that they are using personal protective equipment (PPE). Welders are exposed to extreme heats and powerful equipment daily, so it is vital PPE is taken seriously. PPE exists to… Continue reading PPE in Welding
Welding is the process of fusing together two or more parts by the means of heat and pressure. Welding is normally used on metals and thermoplastics. The type of welding that is used can depend on a number of factors, but form and thickness of the material is usually the determining factor. As welding and… Continue reading Common Welding Issues: How to Correct Them
Metal Inert Gas (MIG) is also known as gas metal arc welding (GMAW). This method of welding is simple in comparison to others methods, which explains why it is often the selected method by beginners. This method is an arc welding process that joins two metals with the help of an arc. The arc is… Continue reading MIG Welding

What is PAW (Plasma Arc Welding)? Plasma arc welding is a process that is very similar to TIG welding, mainly due to the arc formation that occurs between the pointed tungsten electrode and the workpiece. The main difference between PAW and TIG lies within the positioning of the electrode; with a plasma weld, the arc… Continue reading Guide to Plasma Arc Welding (PAW)
