TIG Welding of Stainless Steel and Aluminium in Kyiv

We perform TIG (argon-arc) welding — a method in which the arc burns in a shielding atmosphere of argon and the metal never contacts the air. That is why the weld comes out clean, with no spatter or scale, and the metal itself keeps its properties. It is the primary way to weld stainless steel, aluminium and thin-walled parts, where a regular MIG welder or a stick electrode would leave a rough weld or burn through the metal.

When you specifically need TIG

TIG welding is chosen when the weld has requirements that other methods cannot meet:

• Stainless steel. Without shielding gas, stainless steel loses its corrosion resistance in the weld zone — over time rust appears around it. Argon prevents this.
• Aluminium and its alloys. Aluminium instantly forms a refractory oxide film, so without argon and alternating current a proper joint is impossible.
• Thin metal. At thicknesses from 0.8 mm heat control is critical — TIG allows you to run the weld precisely without burning through the part.
• Visible welds. Where the joint stays in sight — railings, furniture, equipment, decorative products — a neat, even weld matters as much as strength.
• Leak-tightness. Vessels, pipelines, tanks: the weld must hold liquid or pressure without pores or leaks.

Stainless steel welding

We work with food-grade and technical stainless steel — AISI 304, 316, 321, 430. We weld vessels, tables and equipment for food production, railings and fences, interior elements, parts for chemical environments.

If required, we clean, grind or polish the weld until it is almost invisible on the surface. For critical products we use internal argon back purging — it removes oxidation from the back side of the weld, which is critical for vessels and pipelines.

Aluminium welding

Aluminium requires a special approach: different polarity, higher thermal conductivity, an oxide film with a melting point far above the metal itself. Without experience the weld comes out porous and brittle — which is why aluminium products are often brought to us after failed attempts to weld them elsewhere.

We weld aluminium profiles and sheet: frames, housings, radiators, machinery parts, decorative structures. We also perform repair welding — restoring cracks, broken brackets, cast parts.

TIG or MIG — which to choose

Both methods are needed, just for different tasks, and we never push the more expensive one where it gives no advantage.

MIG/MAG welding is faster and cheaper on long welds in mild steel of medium thickness: frameworks, frames, steel structures. TIG welding is slower but gives a cleaner, more precise weld — we use it for stainless steel, aluminium, thin metal and everything that stays in sight. If you don't know what your product needs — describe the task, and we will tell you how to do it right without overpaying.

How much TIG welding costs

The cost depends on the material and thickness, the length and number of welds, how hard the joint is to access, the requirements for cleaning and polishing, and whether internal gas purging is needed. Repair work is priced separately — there the condition of the part matters more than the length of the weld.

What we fabricate and repair

Stainless steel vessels, tanks and reservoirs; tables, sinks and equipment for kitchens and production facilities; railings, fences, handrails; aluminium housings, casings and frames; pipeline assemblies; decorative products with a visible weld. A separate line of work is repair: restoring cracks, welding on broken-off elements, patching burned-through spots.

Combined with other operations

TIG welding is rarely a standalone operation. Parts first go through laser cutting and bending, and after welding — metalwork finishing, grinding and, if needed, powder coating. All of this happens at one facility, so the part does not travel between subcontractors, and one company is responsible for the result.
