TIG welding, or Gas Tungsten Arc Welding (GTAW), is a welding process that uses a tungsten electrode and shielding gas to create strong, clean welds. It’s commonly used in industries like aerospace and automotive, requiring skill but offering precise results. In this blog, we will cover precisely what TIG welding is, its benefits, and its importance within the welding industry. Keep reading to find out more!
TIG welding, or Gas Tungsten Arc Welding, is a welding process that uses a non-consumable tungsten electrode to create a strong, clean weld. A shielding gas, usually argon, protects the weld from contamination.
TIG welding is used daily in industries. It is commonly used for repairing and manufacturing automotive parts, aerospace components, stainless steel structures, and high-pressure pipework.
Welders also use it for custom metal fabrication, furniture making, and artistic metalwork. Due to its ability to work with thin metals and delicate materials, it is often used in medical equipment, jewellery repair, and food-grade welding. Whether for industrial applications or small-scale projects, TIG welding is valued for its control and high-quality results.
TIG welding offers numerous advantages, particularly for welders looking for precision and control in their work. One of the biggest benefits is exceptional weld quality, as TIG welding produces clean, precise welds with minimal spatter. This reduces the need for post-weld cleaning, saving time and effort.
Another advantage is greater control over the welding process. With a foot pedal or hand control, welders can finely adjust heat input, which is crucial when working on thin materials or intricate designs. This level of precision allows for smoother, stronger welds, reducing the risk of warping or burn-through.
TIG welding is also highly adaptable, enabling welders to work with a variety of metals, including stainless steel, aluminium, titanium, and even exotic metals like magnesium. Unlike other welding methods, TIG welding allows for both autogenous welding (without filler metal) and controlled filler addition, providing flexibility in different applications.
Additionally, the lack of flux and minimal fumes creates a cleaner and safer working environment, reducing health risks for welders. While TIG welding requires more skill and practice, those who master it benefit from better job opportunities, as industries like aerospace, automotive, and custom fabrication highly value TIG welding expertise.
If you are seeking greater precision, results, and career growth, TIG welding is an invaluable skill to develop.
TIG welding involves high temperatures, electrical currents, and hazardous fumes, so following proper safety procedures is essential. In the UK, the Health and Safety Executive (HSE) provides guidelines to reduce risks and ensure a safe working environment. Here are the 5 main examples of safety around TIG welding.
Welders must wear the right protective gear to prevent burns, eye damage, and exposure to harmful fumes. This includes an auto-darkening welding helmet, flame-resistant clothing, heat-resistant gloves, and steel-toe boots.
Proper ventilation is crucial to prevent exposure to harmful fumes, especially when welding metals like stainless steel and aluminium. Work areas should have local exhaust ventilation (LEV) or fume extraction systems, and in some cases, welders may need respiratory protection.
Since TIG welding uses high-frequency electrical currents, preventing electric shock is critical. Welders should ensure that equipment is properly grounded, keep hands dry, and avoid working in damp conditions.
To reduce fire hazards, welders must keep flammable materials away, have a fire extinguisher nearby, and store gas cylinders safely. Regular equipment checks help prevent gas leaks and overheating.
Proper training and risk assessments are required to ensure compliance with UK safety regulations. Employers must assess potential hazards before welding begins, and welders should be trained in safe practices, emergency procedures, and equipment handling.
Following these 5 key safety procedures helps create a safer welding environment while reducing the risk of accidents and health issues.
