简介：Tungsten argon arc welding, also known as tungsten inert gas shielded arc welding, it is to use pure or activated tungsten electrodes, tungsten inert gas - argon as shielding gas shielded welding method. Tungsten rod electrode conductive role, don't melt, after electrify produce electric arc between tungsten electrode and workpiece. In the process of welding can wire filling can not wire filling. When the fill welding wire, welding wire from tungsten add ahead. Can be divided into the manual tungsten argon arc welding welding and automatic welding, which has been widely applied in the manual tungsten argon arc welding.
