What is the difference between CO₂ welding and TIG welding?
CO₂ welding (semi‑automatic in carbon dioxide atmosphere) is used for welding carbon steels – it is a fast and economical method suitable for structural elements. TIG (tungsten inert gas) welding is used for stainless steels, aluminum, and non‑ferrous metals when a high‑quality seam and aesthetic appearance without pores or spatter are required.
Which metals do you weld using these methods?
With CO₂ welding we join carbon and low‑alloy steels. With TIG welding – stainless steel, aluminum, copper, titanium, and their alloys. If necessary, welding of dissimilar metals is possible – check feasibility with our engineers during order confirmation.
What thicknesses of metal do you weld?
CO₂ welding is used for metal thicknesses from 1.0 to 20 mm and more. TIG welding is effective for thin‑wall products from 0.5 mm. For very thin metal (less than 0.5 mm), we recommend considering laser welding, which provides a minimal heat‑affected zone.
Can I order only welding without other operations?
No, we do not accept welding as a separate service – only as part of a full product manufacturing cycle. This allows us to control geometry and part preparation at all stages and guarantee the quality of the final result.
How is weld quality ensured?
Weld quality is controlled visually and with measuring tools for compliance with drawing requirements: weld leg, uniformity, presence of burn‑through or porosity. For critical structures, non‑destructive testing is available upon request. All products undergo TCD inspection before shipment.
Is surface preparation needed before welding?
Yes – surfaces in the welding zone must be cleaned of oxides, oil, paint, and contaminants. This is especially important for stainless steel and aluminum to prevent weld porosity. When ordering a full cycle (cutting → bending → welding), we perform surface preparation ourselves.
How much does metal welding cost?
The cost depends on the welding method, metal type and thickness, total length and complexity of welds, number of parts in the assembly. CO₂ welding is generally cheaper than TIG.
