Services

Our technical experts work with you to develop individualised solutions to optimise your operations. Our welding specialists will help you select the most appropriate gases and equipment and consumables for cost-effective and high quality solutions.

Our total welding solutions offer versatility, high quality product, reliable performance, higher productivity, lower cost and safe environmentally friendly operation for welding processes such as the following:

Electric or Arc welding

Welding processes that use a welding power supply to create an electric arc between an electrode and the base material to melt the metal at the welding point. These can use direct or alternating current and consumable or non-consumable electrodes. The welding region is often protected by inert or semi-inert shielding gas and/or a filler material.

Arc welding is widely used because of its low capital and running costs and includes:

• MIG or Metal Inert Gas Welding – suitable for welding all common materials and many of the less common ones too. This flexible and adaptive process is used to obtain high productivity and high quality results.
• TIG or Tungsten Inert Gas Welding – less productive but mainly suited to welding of sheet materials and for putting in the root run of pipe butt welds.
• MMA or Manual Metal Arc Welding – low productivity fusion welding process but versatile as it welds all sorts of components, does not require a shielding gas and therefore can be used outdoors.
• FCAW or Flux Cored Arc Welding – a more productive and higher quality variant of MIG but which produces more particulate fume.
• MCAW or Metal Cored Arc Welding – a more productive alternative of MIG but which produces significant fumes.
• Submerged Arc Welding – mechanised arc welding process specifically used to weld carbon, carbon-manganese, alloys and stainless steel, capable of very high weld deposition rates and welding speeds.
• Plasma Welding – widely used in automatic installations for the construction of vessels or containers in stainless steel, and for high pressure pipe welding. It uses 2 gas flows: a constriction and a shielding gas.

Gas welding or oxy-fuel welding

The heat needed to melt the metal comes from a fuel gas burning with oxygen in a torch. It is also called oxyacetylene welding since acetylene is the predominant choice for fuel gas.

Spot welding

This process uses two shaped copper alloy electrodes to concentrate welding current and force between the materials to be welded. Spot welding is typically used to weld steel sheet metal in automotive body applications or aluminium alloys and can easily be fully automated.

Laser welding

Laser welding offers the advantages of deep penetration and high speed. It is used where other welding processes can’t deliver either the required distortion control or productivity. Depending on material and application, the process can use a variety of shield gases based on helium, argon or mixtures.
