A TIG welder is a skilled tradesperson proficient in Tungsten Inert Gas (TIG) welding. This is a fusion welding process where an electric arc burns between a non-consumable tungsten electrode and the workpiece. The welding area is protected from environmental influences by inert shielding gas (e.g., argon).
Typical duties of a TIG welder include welding pipes, sheets, and beams made of stainless steel, aluminum, or nickel alloys. These tasks are common in pipeline construction, aerospace engineering, or equipment manufacturing.
The TIG welding process is characterized by its high seam quality and precise control of the molten pool. Unlike MIG or MAG welding, the filler material is fed separately, allowing for exceptionally clean and controlled welds, with almost no spatter or welding fumes.
Due to these properties, the process is preferred where aesthetically pleasing joints and maximum strength are required.
Precision, technical understanding, and manual dexterity are essential prerequisites. The profession is ideal for those who enjoy detailed work and are passionate about technology. Reading technical drawings is also an important skill.
Concentration is crucial, as TIG welding requires a great deal of fine motor control.
Becoming a TIG welder typically involves a vocational background in metalworking, such as fabrication mechanics or plant mechanics, followed by specialization.
A key factor is the welder qualification certificate according to DIN EN ISO 9606-1 (steel) or DIN EN ISO 9606-2 (aluminum). These certificates are mandatory in many industrial sectors and must be renewed regularly.
Career changers can also acquire qualifications through specialized courses and continuing education programs at training providers or welding technical institutes (SLV).
TIG welding is used wherever high-quality, spatter-free weld seams are required:
Aerospace industry
Power plant and industrial plant construction
Chemical industry
Food production (hygienic piping systems)
Vehicle construction and bicycle frame manufacturing
TIG welders are valued specialists with great responsibility in these sectors.
TIG welding involves non-consumable tungsten electrodes, high-performance welding power sources, shielding gas systems, and, if necessary, filler materials.
Commonly used items include:
Argon as shielding gas
Thin and thick sheets made of stainless steel or aluminum
Manual or automated TIG welding units
TIG welders must operate, maintain, and monitor this equipment with safety in mind.
The TIG process offers many advantages over other welding methods:
No welding spatter
Minimal welding fumes
Extremely clean seams
Ideal for difficult positions and fine work
Compared to stick welding, TIG welding is often the better choice when appearance and precision are crucial.
TIG welders are true experts when it comes to high-quality, durable, and precise welds. Their expertise is essential in many industrial fields. If you love technology, enjoy detailed work, and seek ongoing development, this is a future-proof career with real potential.
TIG and WIG refer to the same process. TIG stands for “Tungsten Inert Gas” (English), while WIG is the German abbreviation “Wolfram-Inertgas”.
TIG welding is perfect for stainless steel, aluminum, nickel alloys, and other non-rusting or heat-resistant metals.
The process demands precision and practice, but with patience and proper guidance—e.g., through courses—it can be mastered successfully.
Depending on previous experience, specialization can take several weeks to months. Often it’s done alongside work through training or SLV courses.
Yes, most industrial applications require a valid welder qualification according to DIN EN ISO 9606, which must be renewed periodically.
