Our highly skilled welders are certified to BS EN 287 and ASME VIII standards, and our procedures to BS EN 288.
Regular, stringent testing ensures that our work is always of a consistently high quality.

Our Welding Quality Plan offers full traceability of all materials and weld data, backed up with weld logs, line isometric drawings and material mill certification identification.

smoke or spatter, and low distortion due to the very localised heat of the arc.

At Delstron, we use TIG (Tungsten Inert Gas) welding because it produces accurate results of the highest quality across a wide range of metals, including stainless steel, aluminium, copper and a range of alloys.

The TIG welding process uses an arc struck between the tungsten electrode and the metal to be welded. The arc heats and melts the metal, a filler rod being added as required. The electrode does not melt as welding takes place, and an inert shielding gas (argon) flows out around the tungsten and the weld preventing oxidisation. (See diagram below).
