If you’re looking for precision, cleanliness, and control in your welding applications, TIG in welding is a process that stands out. Whether you’re fabricating stainless steel handrails or working on intricate aluminium components, TIG welding offers unmatched quality and a cleaner finish than most other welding techniques.
But what exactly is TIG welding, how does it work, and what equipment do you need? In this guide, we’ll break it all down and show you where to find the best TIG welders in the UK — right here at Welder’s Choice.
What Does TIG in Welding Mean?
TIG stands for Tungsten Inert Gas welding, also known as GTAW (Gas Tungsten Arc Welding). It’s a manual welding process that uses a non-consumable tungsten electrode to produce the weld. The weld area is shielded from atmospheric contamination by an inert gas, typically argon or a mix of argon and helium.
TIG in welding is highly valued for its ability to produce clean, high-quality welds with excellent bead appearance. It’s ideal for applications that require precise, low-spatter welds — including aerospace, automotive, food-grade stainless fabrication, and pipe welding.
Key Features of TIG Welding
Precision and control: You control heat input and filler material independently.
Versatility: Works on thin or thick materials, including aluminium, stainless steel, copper, titanium, and more.
No spatter: Because no filler is required unless added manually, there’s minimal mess.
Strong, clean welds: Especially useful where weld aesthetics or x-ray quality welds are needed.
How Does TIG Welding Work?
TIG in welding uses an arc between the non-consumable tungsten electrode and the workpiece. The welder may use a filler rod, but it’s not always necessary. The arc and weld area are protected by a stream of inert shielding gas.
In TIG welding, you often need to manually feed the filler rod with one hand while holding the torch in the other — giving you full control but requiring more skill than MIG or Stick welding.
What Do You Need for TIG Welding?
To perform TIG in welding, you’ll need:
A TIG welder with DC or AC/DC output if you plan to weld aluminium.
A TIG torch with a tungsten electrode.
Filler rods appropriate for your base material.
An inert shielding gas, usually argon.
A gas regulator or flow meter.
PPE: gloves, auto-darkening welding helmet, and fire-resistant clothing.

Introduction to Welding Processes
Welding is a crucial process in various industries, including manufacturing, construction, and automotive. It involves joining two or more metal pieces together using heat, pressure, or both. There are several welding processes, each with its unique characteristics, advantages, and disadvantages. Two popular welding processes are Laser Welding and TIG (Tungsten Inert Gas) Welding. In this article, we will explore the differences between these two processes, their advantages, and disadvantages.
Understanding Laser and TIG Welding Processes
Laser and TIG welding represent two distinct approaches to metal joining, each with specific advantages in manufacturing applications. These processes differ in their heat source, application methods and precision levels.
Basic Principles of Laser Welding
Laser beam welding employs concentrated light energy to create precise, localized heat for joining metals, plastics, and composites. Pulsed laser welding minimizes the contact between the laser and the workpiece, allowing for quick and efficient spot welds while preventing issues associated with excessive heat input and improving weld quality. A focused laser beam generates temperatures up to 25,000°C, forming a keyhole in the material that creates deep, narrow welds. The process occurs in a controlled environment with shielding gas to prevent oxidation.
Key characteristics of laser welding:
Creates welds as narrow as 0.4mm in diameter
Produces minimal heat-affected zones
Operates at speeds up to 10 metres per minute
Functions without direct contact with the workpiece
Requires minimal post-weld cleanup
How TIG Welding Works
TIG (Tungsten Inert Gas) welding, a traditional technique, uses a non-consumable tungsten electrode to generate an electric arc. TIG welding methods are crucial for improving weld penetration and quality, with specific techniques minimizing the Heat Affected Zone (HAZ) and distortion. The TIG welding process offers advantages such as manual control over heat input and steady heat distribution, but it also has limitations like weld penetration issues.
