TIG Welding is an arc method where the heat required for welding emerge by an arc formed between an non-consumable electrode (tungsten electrode) and the workpiece.The electrode, welding bath, arc and the areas of the workpiece near to the welding machine are protected against the hazardous impact of the atmosphere by the gas or mixed gas supplied from the welding torch. The gas should be able to fully protect the welding area, otherwise even a very small air ingress come out errors on the welding metal.
- The TIG welder can be performed both manually and automatically with welding systems to make welding seam, perodically weld, spot weld.
- Because the electrode is not consumed, it is performed by melting the base metal or using an additional welding metal
- Welding may be performed in any position and it is particularly suitable for welding of thin materials.
- It provides depths and non-porous welds in root pass welding works.
- Since the heat input is concentrated in the weld zone, the workpiece where the deformation is low
- It also provides a steady welding seam and removing of the weld bead is not necessary.
- Metal agglomeration speed of TIG welding is lower than other arc welding methods.
- It is not an economical method at the welding of thick-section materials.
