Q: Which industries use gas welding?

We use gas welding in the automotive industry (body and exhaust system repairs), production (metal furniture, railings), construction (steel structures, pipes), aerospace (precision repairs), shipbuilding (vessel components), and maintenance (rapid machine repairs and reconditioning of worn parts).

Q: When should I choose gas welding over other methods?

Gas welding is the best choice when: you need mobility — no electrical power supply is required; you are working in field conditions; you are welding thin sheets that require precise heat control; or you want low equipment and operating costs. For large batches and thicker materials, MIG/MAG methods will be more efficient.

Q: What materials can be gas welded?

Gas welding is suitable for joining all types of steel (carbon, stainless, alloy) as well as non-ferrous metals — copper, brass, and aluminium. It is particularly effective on thin sheets, where precise heat control prevents burn-through and distortion.

Q: What is gas welding and how does it work?

Gas welding (method 311) joins metal edges by melting them with an acetylene flame. A mixture of acetylene and oxygen produces a temperature of about 3,100 °C, sufficient to join most metals. It is one of the oldest and most versatile welding methods, valued for simplicity and mobility.
