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. Primarly developed for high performance materials (tools, aeronautics, nuclear) gas quenching can be performed with nitrogen, argon, hydrogen or helium, pure or in mixtures, depending upon the material specifications.

Brazing processes are either manual or automatic.

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.

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 Plasma welding process is a further development of the TIG welding process.

Your application involves hardfacing pieces as moulds. And you use manual powder guns with oxy-acetylene flame process.

This process uses an electric arc to cut the metal, and is widely used on any metal to obtain good cut properties and high productivity.

Flame welding is performed with a welding torch and exclusively with an oxy-acetylen or oxy-crylen (available in some countries) flame.

Stainless steels, carbon steels and non-ferrous materials are annealed to trigger the relaxation of internal stresses and give a softer product. Annealing can be achieved in many types of batch or continuous furnaces at temperatures below their phase transformation temperature.

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.

The High Velocity Oxy-Fuel process is used in various industries such as the aeronautics industry, oil and petroleum equipment, turbines, etc. This process is 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.

Your welding process is MIG/MAG - GMAW

During carburizing (carbonitriding) operations, carbon (and nitrogen) is brought to the surface of steel components and diffuses to produce a hard martensitic surface layer after quenching.Traditionally, the carbon comes from a hydrocarbon (natural gas or propane), partly oxidized in an endogas generator to produce a CO/H2 atmosphere. For nitriding, the N agent comes from ammonia cracking at the surface. Nitrogen accelerates the diffusion of carbon into the treated parts.

Sintered mechanical components are commonly produced in continuous furnaces, where the sintering operations are carried out in several, but strongly interconnected steps.

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