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.

This means that lower preheat levels are needed than with MMA welding. Alumaxx Plus is the high performance argon – helium shielding gas 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. The shielding gas can be: Usually the gas is argon, but helium by itself or mixed with argon may be used for special applications. The table gives a guide to the selection of wire diameter but the exact relationship depends on the material and the shielding gas.

Inomaxx 2 is recommended for welding ferritic and austenitic grades of stainless steel of all thicknesses in dip, spray and pulse transfer modes. The arc and the weld are protected from atmospheric contamination by a gas shield.

The welder controls the speed of travel to ensure that the weld pool does not run ahead of the arc as this would cause lack of fusion. Voltage controls the profile of the weld. These offer the advantages of higher welding speeds and easier control of fillet weld profiles. Wire diameter depends on the current required.

Argon – hydrogen mixtures can be used for stainless steel. The term Spray Transfer is used to describe this type of operation.

These two techniques are also used for welding sheet material. 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.

This allows the arc to fuse the parent metal ahead of the weld pool and gives the best penetration. 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. An electric motor feeds the wire into the arc and the power source keeps the arc length at a preset value leaving the welder to concentrate on ensuring complete fusion of the joint.

Direct current with the electrode connected to the negative terminal of the power source is used for:. See pages 9 and Arquivos Semelhantes Manufacturing Steel Construction.

Principles Tungsten inert gas shielded welding is usually called TIG welding. The process can be operated at currents within the range A for welding plates, thick walled pipes and slodagem in the flat position. 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.

Ferromaxx is a range of selected mixtures aposttila argon, carbon dioxide and other gases to provide ideal arc conditions for spatter free welding of steels. The electrode is not melted and any filler metal needed to build up the weld profile is added separately.

Inductance in Dip Transfer stabilises the arc and minimises spatter. 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.

Optimum conditions can be established for a range of applications which are readily reproduced by the welder.

Pure argon is particularly effective for welding aluminium and its alloys. It uses an arc between a tungsten electrode and the work to fuse the joint. For carbon, carbonmanganese, high strength low alloy steels and stainless steels, flux cored wires can be used. Gas shielded metal arc welding is a semi-automatic process which is suitable for both manual and mechanised operation. Inomaxx Plus is the choice for apsotila all thickness of ferritic and austenitic stainless steels in dip, spray and pulse transfer and with metal cored wires.

Wire feed speed sets the welding current. Also used for copper and nickel. It is known by a variety of names: Parte 2 de 9 Gas shielded metal arc welding is a semi-automatic process which is suitable for both manual and mechanised operation.
