Welding tig

In general, however, it can be stated that each metal suitable for fusion welding procedure can be welded using the WIG procedure.
As tungsten inert gas welding can be used both manually and as an automated process, this procedure is used in very many areas. TIG welding is always used if particularly high weld quality and properties are required. TIG welding can be used in all positions.
For this reason, TIG welding can not be used outdoors.



TIG welding
TIG weldingTIG welding is one of the fusion welding procedures. TIG welding is mainly used for thin sheets made of aluminium and stainless steel, but can also be used for normal steel sheets and plates.
The current required for welding the workpiece is supplied via a tungsten electrode (2). Unlike MIG or MAG welding the electrode does not melt.
It is supplied directly via the welding head (1). In TIG welding the welder can match the current intensity and the quantity of filler metal to the workpiece (6). In TIG welding the filler metal is added continuously or drop by drop.
Nikolai Nikolaijewitsch Bernados invented arc welding between 1880 and 1887. In 1881, he demonstrated this procedure for the first time at the Paris exhibition.
TIG welding was invented in 1946 in the USA. The original name was argon arc welding and it represented a further development of the carbon arc welding procedure.
TIG Welding-- Technical information
In TIG welding a differentiation is made between 2 variants. On the one hand, it is welding with direct current, which is the most frequently used type. In general, however, it can be stated that each metal suitable for fusion welding procedure can be welded using the WIG procedure.
As tungsten inert gas welding can be used both manually and as an automated process, this procedure is used in very many areas. TIG welding is always used if particularly high weld quality and properties are required. One hand is used to add the filler metal while the other hand holds the welding torch.
Advantages
This welding procedures is very fast. TIG welding can be used in all positions.
Disadvantages
This welding procedure is very susceptible to wind. For this reason, TIG welding can not be used outdoors.
