An electric motor feeds the wire into soldgem 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. The electrode is not melted and any filler metal needed to build up the weld profile is added separately. This means that lower preheat levels are needed than with MMA welding.

Ferromaxx Plus apostlia 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.

These offer the advantages of higher welding speeds and easier control of fillet weld profiles. The term Spray Transfer is used to describe this type of operation.

Usually the gas is argon, but helium by itself or mixed with argon may be used for special applications. Spldagem used for copper and nickel. Direct current with the electrode aposhila to the negative terminal of the power source is used for:.

Parte 2 de 9 Gas shielded metal arc welding is a semi-automatic process which is suitable for both manual and mechanised operation. For carbon, carbonmanganese, high strength low alloy steels and stainless steels, flux cored wires can be used.

Pure argon is particularly effective for welding aluminium and its alloys. The arc and the weld are protected from atmospheric contamination by a gas shield. Optimum conditions can be established for a range of applications which are readily reproduced by the welder. Wire feed speed sets the welding current. These two techniques are also used for welding sheet material.

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.

It is known by a variety of names: Inomaxx Plus is the choice for welding all thickness of ferritic and austenitic stainless steels in dip, spray skldagem pulse transfer and with metal cored apstila. The table gives a guide to the selection of wire diameter but the exact relationship depends on the material and the shielding gas.

The process can be operated at currents within the range A for welding plates, thick walled pipes and sections in the flat position.

Arquivos Semelhantes Manufacturing Steel Construction. Wire diameter depends on the current required. Argon – hydrogen mixtures miig be used for stainless steel. 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 so,dagem arc to fuse the parent metal ahead of the weld pool and gives the best penetration.

Voltage controls the profile of the weld.

See pages 9 and 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.

It uses an arc between a tungsten electrode and the work to fuse the joint. Principles Tungsten inert gas shielded ed is usually called TIG welding. 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.

Gas shielded metal arc welding is a semi-automatic process which is suitable for both manual and mechanised operation. 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.

Alumaxx Plus is the high performance argon – helium shielding gas for MIG welding aluminium and it s alloys of all thickness in spray mjg pulse transfer modes Soldagme Plus is also the recommended gas for TIG welding aluminium and copper.

Inductance in Dip Transfer stabilises the arc and so,dagem spatter. 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.

Inomaxx 2 is recommended for welding ferritic and austenitic grades of stainless steel of all thicknesses in dip, spray and pulse transfer modes.
