Brazing

They are used for heat exchangers in air conditioning, taps, sanitary equipment and compressor parts.

Heat Shrinking

This process allows rectification of the distortions on the thermally affected zone during the welding cycle. It involves heating a flame very quickly or over a narrow area of a sheet or welded set of pieces. This shrinking process, particularly used in the shipyards, can be used on carbon or stainless steels. Gases that are used for the heating flame are oxygen and acetylene.

Flame Cutting

Flame applications for cutting process use an oxy-fuel flame and straight oxygen as a cutting jet to separate the metal. This process is used on carbon steels and sometimes on stainless steels with iron powder (heavy thicknesses of over 60mm). It is either manual or automatic and is widely used due to its high flexibility and excellent cut properties. This process is mainly used in metal fabrication, shipyards, boilers, scrapping, etc.

Plasma Cutting

Plasma cutting is used, manually or automatically, to obtain excellent cut properties via an electric arc. Carbon steels of up to 15 mm are cut with oxygen. Stainless steels or aluminum are cut with nitrogen, while heavy thicknesses of up to 60-80 mm can be cut with an argon/hydrogen cutting gas.
