These offer the advantages of higher welding speeds and easier control of fillet weld profiles.

See pages 9 and 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. Inductance in Dip Transfer stabilises the arc and minimises spatter. 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 arc and the weld are protected from atmospheric contamination by a gas ce. Arquivos Semelhantes Xpostila Steel Construction. It is known by a variety of names: Principles Tungsten inert gas shielded welding is usually called TIG welding.

A low voltage 18 40Vhigh current 60 A arc between the end of a ve electrode and the work provides the heat needed for the welding operation. The table gives a guide to the selection of wire diameter but the exact relationship depends on the material and the shielding gas. The term Spray Transfer is used to describe this type of operation. Also used for copper and nickel. The process can be apostola at currents within the range A for welding plates, thick walled pipes and sections in the flat position.

Wire diameter depends on the current required. The electrode is not melted and any filler metal needed to build up the weld profile is added separately.

Ferromaxx 15 is the choice for welding apoetila, carbonmanganese, high strength low alloy steels and coated steels in dip, spray and pulse transfer modes for all thickness. 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. 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.

It uses an arc between a tungsten zoldagem and the work to fuse the joint.

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. Wire feed speed sets the welding current. Voltage controls the profile of the weld.

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.

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 ed special applications.

Ferromaxx Plus is the multi-purpose gas for welding carbon, carbonmanganese, high skldagem 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. 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.

Optimum conditions can be established for a range of applications which are readily reproduced by the welder. This means that lower preheat fe are needed than with MMA welding.

The shielding gas can be: These two techniques are also used for welding sheet material. Parte 2 de 9 Gas shielded metal arc welding is a semi-automatic process dd is suitable for both manual and mechanised operation.

Inomaxx 2 is recommended for welding ferritic and austenitic grades of stainless steel of all thicknesses in dip, spray and pulse transfer modes. Direct current with the electrode connected to the negative terminal of the power source is used for:. Inomaxx Plus is the choice for welding all thickness of ferritic and austenitic stainless steels in dip, spray and pulse transfer and with metal cored wires.

Argon – hydrogen mixtures can be used for stainless steel.
