L.E.V Testing

Local exhaust ventilation (L.E.V) is often called dust and/or fume extraction; it can help keep the environment clean before people breathe in these harmful substances. Local Exhaust Ventilation explained… Every year many employees contract occupational asthma and other lung diseases, as reported by The Health and Safety Executive (HSE). These health issues develop because of… Continue reading L.E.V Testing

Colours In Welding: What Do They Mean?

Welding is an art.  As with any art, colour plays a crucial factor. Welding is no different, and it can produce different colours depending on the type of weld and the metal or material being welded. Often, the colour of the weld can indicate a lot about it.  Whilst there are many different and reliable… Continue reading Colours In Welding: What Do They Mean?

What Is Glass Welding Used For?

An Overview of Glass Welding Glass welding is most commonly used during the practice of ‘glassblowing’. Glassblowing is a technique that involves inflating and manipulating hot, molten glass into shapes or bubbles using a blowpipe, also referred to as a blow tube. The process of glassblowing is accomplished by heating glass and turning it into… Continue reading What Is Glass Welding Used For?

Differences Between Coded Welders vs. Certified Welders

Unlike other trades, where you are expected to pass through different hoops and have certain specialist certifications and qualifications before you become a fully qualified tradesperson, the welding industry is a little different. Some employers do ask to see certificates before employing a welder, but this isn’t the norm.    Usually, employers are more concerned… Continue reading Differences Between Coded Welders vs. Certified Welders

Submerged Arc Welding (SAW)

What is Submerged Arc Welding? This arc welding process involves the formation of an arc between a continuously fed electrode and a workpiece. This creates a blanket of powdered flux, which helps protect the weld zone. During welding, the arc is submerged beneath the flux blanket and it is not usually visible. This type of… Continue reading Submerged Arc Welding (SAW)

Guide to Plastic Welding

Plastic welding is a fabrication process, and one that not many people are aware exists. Broken plastics objects can undergo a cosmetic change to bring it back and save it from being thrown away. When we buy something that has plastic coating, and it gets broken, typically we replace it. However, plastic is very malleable… Continue reading Guide to Plastic Welding

Advantages & Disadvantages of Explosion Welding

What is Explosion Welding? Explosion welding is achieved by accelerating one of the components at an extremely high velocity through the use of chemical explosives. It is a solid-state welding process that is often used to clad carbon steel with a thin layer of corrosion-resistant material such as stainless steel, nickel alloy, titanium or zirconium.… Continue reading Advantages & Disadvantages of Explosion Welding

Guide to Energy Beam Welding

What is Energy Beam Welding (EBW)? Energy beam welding otherwise referred to as electron-beam welding, is a fusion welding process. The method involves a beam of high-velocity electrons that are applied to two materials that are being joined together. The pieces melt and fuse together as the kinetic energy of the electrons is transformed into… Continue reading Guide to Energy Beam Welding

What is Butt Welding?

What is a butt weld? A butt weld is a commonly used welding technique that can be automated or done by hand on steel pieces by a welder. This technique can also be done with brazing copper pieces. Now, you may be thinking, what is a butt welding used for? Well, it is used to… Continue reading What is Butt Welding?

The Science of Cold Welding: How to Join Metals Without Heat

What is Cold Welding? As you may have suspected from the term ‘cold welding’, there isn’t any heat involved. Cold welding is the process of joining two metals or materials together without using any heat. Now, this may sound impossible and contrary to everything you previously thought you knew about welding. But, it is possible… Continue reading The Science of Cold Welding: How to Join Metals Without Heat
