Alumaxx Plus is the high performance argon – helium shielding soldabem for MIG welding aluminium and it s alloys of all thickness in spray and pulse transfer modes Alumaxx Plus is also the recommended gas for TIG welding aluminium and copper. It uses an arc between a tungsten electrode and the work to fuse the joint.

Processos de SOl by Tandara Almeida on Prezi

An electric motor feeds the wire into the arc and the power source keeps the solsagem length at a preset value leaving the welder to concentrate on ensuring complete fusion of the joint. The process can be operated at currents within the range A for soldqgem plates, thick walled pipes and sections in the flat position.

The arc and the weld are protected from atmospheric contamination by a gas shield. This means that lower preheat levels are needed than with MMA welding. For carbon, carbonmanganese, high strength low alloy steels and stainless steels, flux cored wires can be used.

Ferromaxx 7 is recommended for carbon, carbon-manganese and high strength low alloy steels up to 10mm thick in dip, spray and pulse transfer modes.

Arquivos Semelhantes Manufacturing Steel Construction. The term Spray Transfer is used to describe this type of operation. It is known by a variety of names: Ferromaxx is a range of selected mixtures of argon, carbon dioxide and other gases to provide ideal arc conditions for spatter free welding of steels. Inomaxx 2 is recommended for welding ferritic and austenitic grades of stainless steel of all thicknesses in dip, spray and pulse transfer modes.

The welder controls the speed of travel to ensure that the weld pool does not run ahead of the arc as this would cause jig of fusion. Ferromaxx Plus is the multi-purpose gas for welding carbon, carbonmanganese, high strength low alloy steels and coated steels of all thickness with solid wires in dip, spray and pulse transfer and with metal and flux cored wires.

Inomaxx Plus is the choice for welding all thickness of ferritic and austenitic stainless steels in dip, spray and pulse transfer and with aposti,a cored wires.

Optimum conditions can be established for a range of applications which are readily reproduced by the welder. Both the molten metal in the weld pool, the tip of the filler wire and the hot electrode are protected from atmospheric contamination by a shield of inert gas.

Direct current with the electrode connected to the negative terminal of the power source is used for:. Argon – hydrogen mixtures can be used for stainless steel. Pure argon is particularly effective for welding aluminium and its alloys. The electrode is not melted and any filler metal needed to dr up the weld profile is apoatila separately.

Principles Tungsten inert gas shielded welding is usually called TIG welding. Also used for copper and nickel.

These two techniques are also used for welding sheet material. See pages 9 and Inductance in Dip Transfer stabilises the arc and minimises spatter. The table gives a guide to the selection of wire diameter but the exact relationship depends on the material and the shielding gas.

Wire feed speed sets the welding current. Wire diameter depends on the current required. A low voltage 18 40Vhigh current 60 A arc between the end of a wire electrode and the work provides the heat needed for the welding operation. Ferromaxx 15 is the choice for welding carbon, carbonmanganese, high strength low alloy steels and coated steels in dip, spray and pulse transfer modes for all thickness.

The shielding gas can be: This allows the arc to fuse the parent metal ahead of the weld pool and gives the best penetration. Usually the gas is argon, but helium by itself or mixed with argon may be used for special applications.

Gas shielded metal arc welding is a semi-automatic process which is suitable for both manual and mechanised operation. Parte 2 de 9 Gas shielded metal arc welding is a semi-automatic process which is suitable for both manual and mechanised operation. These offer the advantages of higher welding speeds and easier control of fillet weld profiles. Voltage controls the profile of the weld.
