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. 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.

Also used for copper and nickel. Argon – hydrogen mixtures can be used for stainless steel. This allows the arc to fuse the parent metal ahead of the weld pool and gives the best penetration.

Parte 2 de 9 Gas shielded metal arc welding is a semi-automatic process which is suitable for both manual and mechanised operation. 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. 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.

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. 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. 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. Principles Tungsten inert gas shielded welding is usually called TIG welding. These two techniques are also used for welding sheet material.

The shielding gas can be: Voltage controls the profile of the weld. Usually the gas is argon, but helium miy itself or mixed with argon may be used for special applications.

An electric motor xe 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. See pages 9 and 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. The process can be operated at currents within the range A for welding plates, thick walled pipes and sections in the flat position.

For carbon, carbonmanganese, high strength low alloy steels and stainless steels, soldgem cored wires can be used. This means that lower preheat levels are needed than with Solfagem welding. It is known by a variety of names: Gas shielded metal arc welding is a semi-automatic process which is suitable for zpostila manual and mechanised operation. It uses an arc between a tungsten electrode and the work to fuse the joint. 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. Inductance in Dip Transfer stabilises the arc and minimises spatter.

The electrode is not melted and any filler metal needed to build up the apsotila profile is added separately. Arquivos Semelhantes Manufacturing Steel Construction.

The term Spray Transfer is used to describe this type of operation. Wire diameter depends on the current required.

Ferromaxx mav 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.

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

These offer the advantages of higher welding qpostila and easier control of fillet weld profiles. Pure argon is particularly effective for welding aluminium and its alloys.
