Weld-Cut provides expertise in all key welding and cutting processes used across all metals-related industries

7 processes in detail

Manual Metal Arc welding (MMA)

Valued for its flexibility, this is one of the most commonly used welding processes.

Manual Metal Arc welding (MMA) is used on a daily basis by DIYers, tradesmen, security metalwork specialists and metal fabricators, as well as on pipe laying work sites. This type of welding consists of creating a high-intensity electric arc between a shielded metal-cored electrode and the metals to be joined.

Tungsten Inert Gas welding (TIG)

This process is commonly used for joining stainless steel, aluminium and aluminium alloys.

TIG Tungsten Inert Gas (TIG) welding enables a very high quality of welding to be achieved in particularly demanding sectors of application, such as pressure vessels, pipelines, food industry containers and aviation. The process uses an electric arc between the metals to be joined and an infusible tungsten-based electrode, located in the welding torch. The filler metal as a rod is applied manually by the welder.

Metal Inert Gas/ Metal Active Gas welding (MIG/MAG)

This semi-automated welding process is widely used in many industry sectors.

Metal Inert Gas/ Metal Active Gas is used in shipbuilding, railroad construction and the production of heavy plants and machinery. The process melts and fuses metals using the intense heat generated by an electric arc between the metals to be joined and a filler wire (solid or flux cored).

Plasma Cutting

The process uses an electric arc to cut metal.

Plasma Cutting is very widely used on all types of metal to achieve high-quality cuts and high levels of productivity. Under certain circumstances, it can achieve a comparable quality level to laser cutting, but at considerably lower production cost.

Submerged Arc Welding (SAW)

Submerged arc welding is a high-yield automated welding process.

Submerged Arc Welding (SAW) is commonly used in industries where thick steel sheets are involved or where long welds are required. The process consists in creating a welded joint between steel components using an electric arc submerged beneath a layer of powdered flux.


Plasma Welding

The preferred applications for this welding process are in pipeline and the metal fabrication operations carried out by companies manufacturing tanks for the food, chemicals and pharmaceutical industries and in the manufacturing of aircraft components.

Plasma welding is an evolutionary development of the TIG process, which uses a constricted arc to achieve extremely high temperatures in a closely focused arc. Its main applications are in automated welding processes.


Oxy-gas welding & Cutting

Oxy-gas welding is the longest-established welding process and one of the historically essential markets for Weld-Cut.

Today, this process is used by plumbers, heating and refrigeration engineers, metal fabricators, security metalwork specialists and DIYers. It is most frequently used for brazing or braze-welding. Oxy-gas cutting is used chiefly in the metal structures demolition industry. This process uses an oxy-combustible flame and pure oxygen as the metal cutting jet.
