Production of non-consumable tungsten tig electrode
Technical characteristic
Tungsten electrodes are non-consumable. They have excellent mechanical properties: hardness, wear resistance, immunity to intense heat, minimum thermal expansion coefficient compared to other metals, good thermal conductivity, exceptional resistance to temperature creep as well as a very high modulus of elasticity.
Fabrication
Technological ductility of tungsten is minimal, but increases with increasing temperature, so it is made into rolled steel by hot work under pressure. Billets are produced first - a stack is made by powder metallurgy. When it is heated, it is expanded on a forging rotary machine - rods with a diameter of 2 - 3 mm are obtained, from which after hot drawing wire ∅ 0,2 - 0,3 mm is obtained.
