Metal Fabrication Industries  [ Return towards  Applications ]

The High Velocity Oxy-Fuel process is used in various industries such as the aeronautics industry, oil and petroleum equipment, turbines, etc. This process can be used - depending on the powder properties (ceramics, metals, carbides, self-fluxing powders) - with various fuel gases such as Hydrogen, Acetylene, FLAMAL,SPRAL, LPG's or Kerosene. In this last case, the oxygen supply is at a high pressure and flow rate. This process has the advantage of producing a high density and a high coating thickness when using carbon dioxide cooling.

MIG: Metal Inert Gas welding (inert gases such as argon, helium or mixes).
These mixes are mainly used for sensitive stainless steels and aluminum or copper alloy welding.

Flame applications for cutting processes require FLAMAL, the oxy-fuel flame and straight oxygen as a cutting jet to separate the metal.
Mainly used in automatic for separating metals of more than 15 mm thickness, this process is efficient on carbon steels and sometimes on stainless steels with iron powder (heavy thickness of over 60 mm).
The high flexibility of this process combined with its excellent cutting performances confer it a very general-purpose character. It is thus very used for manual and automatic operations in metal fabrication, shipyards, boilers, scrapping, installation, etc.

Thermal coating, wire flame coating - anti-corrosion or wear-resistant coating.

Control of the atmosphere composition, flow rate and pressure in each zone of your continuous, open-ended furnace is a key factor in the quality of your treatment, the economics of your process and the safety of your workforce.

Gas quenching is an environmentally friendly alternative solution to oil or salt bath quenching applications. Associated with low pressure processes (carburizing, nitriding, annealing...), gas quenching offers a better control of the distortion and limits post operations such as rectification. Primarily developed for high performance materials (tools, aeronautics, nuclear) gas quenching can be performed with nitrogen, argon, hydrogen or helium, pure or in mixtures, depending on the material specifications.

A laser beam is focused on the base metal, and a cutting jet ejects the molten metal. This process is used mainly on thin metals requiring high precision and high productivity.

The fitting process is based on the expansion (by an oxy-fuel flame) or contraction (by a cryogenic fluid) of a work piece in order to locate and fix it in a dedicated place.

This process is used in such industries as the automotive (e.g. valves), aeronautics (jet engines), power plant construction (gas turbines), printing (cylinders), pulp and paper (cylinders, knives, etc.), and medical implant supplies, where very high quality and reliability are required.

The laser beam produced by a CO2 or a solid state YAG cavity is used for high penetration, high-speed welding processes, where mainstream processes can not deliver the required distortion and/or productivity.
