TIG WELDING SERVICES

Characteristics of the TIG process

TIG (Tungsten Inert Gas) is an arc welding process under inert gas shielding, mainly argon. The process uses a non-consumable tungsten electrode. The electric arc between the electrode and the part being welded melts the metal in the joint area. Welding can be performed with or without filler material. Shielding gas prevents oxidation of the molten metal and ensures welding process stability.

TIG welding under argon shielding allows precise control of heat input, the formation of visually appealing welds and the joining of thin parts.

TIG is particularly suitable for welding stainless steel, aluminium and products where surface quality, precision and minimal welding spatter are important.

Materials and process selection

TIG welding of aluminium
When joining aluminium alloys, we select welding parameters and filler material according to the alloy grade, thickness and joint geometry. This applies to housings, brackets, panels and components made from aluminium profiles, among other products.

TIG welding of carbon steel
For carbon steel, the method allows precise joints to be made in metal parts and equipment components. We select the scope of work according to the thickness, joint design and strength requirements.

TIG welding of stainless steel
TIG welding is used for stainless steel and acid-resistant steel where appearance, leak tightness and surface quality are important. The steel grade and product operating conditions determine the requirements for filler material and joint preparation.

TIG welding of brass
The feasibility of welding brass depends on the specific alloy grade and joint design. The presence of zinc can make the process more difficult and promote weld porosity. We assess the suitability of TIG and the feasibility of carrying out such an order individually after analyzing customer documentation.

Products for which TIG welding is used
The process is used to manufacture sheet metal parts and structures requiring visually appealing welded joints, accurate geometry and high surface quality.

Main types of products:

• Stainless steel products — housings, guards, panels, tanks and industrial equipment components.
• Equipment housings and guards — thin-walled welded structures, protective guards and metal modules.
• Leak-tight structures — tanks, trays, containers and housings with specified joint leak tightness requirements.
• Aluminium parts — housings, brackets, panels and welded equipment components.
• Retail and furniture equipment — decorative components, support frames, stands and structures with visible welded joints.
• Components for food processing and process equipment — stainless steel parts with increased requirements for weld quality and surface treatment.

TIG is most effective for thin sheet metal products, short and complex welded joints, and structures where weld quality takes precedence over welding speed.

Is gasless TIG welding possible?

TIG requires a shielding gas, most often argon, that protects the electrode and the molten metal. Welding without filler material, described for this method, also involves a gas shield.

Advantages of TIG welding

• Heat input control. We adapt welding parameters to the material and component thickness to limit distortion and achieve the required joint geometry.
• High weld quality. The ability to produce even, visually appealing joints with minimal spatter.
• Precise process control. Adjusting the welding current and filler material feed allows control over weld formation.
• Thin sheet metal welding. The ability to join thin parts with correctly selected parameters while minimizing thermal distortion.
• Material versatility. The ability to weld carbon steel, stainless steel, aluminium and a range of other metals and alloys.
• Surface quality. The absence of a slag layer and minimal metal

The ability to produce leak-tight joints. The process is suitable for manufacturing products requiring leak tightness, provided that the welding procedure is followed and the necessary inspection is carried out.

Process limitations

When selecting TIG, the characteristics of the welding process should be considered:

• Lower productivity. Welding speed is usually lower than with MIG/MAG, particularly when making long welds.
• Higher labour costs. Longer welding times and welder qualification requirements increase the labour intensity of production.
• Sensitivity to part preparation. Contamination, oxide layers and inaccurate edge fit-up can negatively affect joint quality.
• Thermal distortion. Despite the ability to control heat input precisely, there is still a risk of warping when welding thin sheets.
• Limited efficiency with thick sections. When welding heavy parts and long welds, the process is often less productive than MIG/MAG.

The choice of TIG depends on the material and part thickness, as well as requirements for appearance, leak tightness, strength and production costs.

TIG welding within the PRITZ production cycle

PRITZ DEVELOPMENT carries out TIG welding as part of comprehensive metal product manufacturing according to customer technical drawings and documentation.

Combining laser cutting, sheet metal bending and welding allows housings, guards, tanks and assemblies to be manufactured with a minimal number of intermediate production operations.

Production planning takes into account welded joint design, surface quality requirements, access to welds, assembly sequence and possible thermal distortion.

Depending on the requirements for the finished product, welding may be followed by weld cleaning and grinding, surface treatment, powder coating and final assembly.
