Micro TIG welding (micro tungsten inert gas), also known as pulse arc welding, is an arc welding process that uses a non-consumable tungsten electrode to produce an arc which creates the weld.
Micro TIG welding is a non-contact process, which, like laser welding, requires an external fixture to apply force to create proper part fit-up. It utilizes a constant current welding power supply which produces high quality welds with minimal heat-affected zones by generating arcs between the workpiece and the tungsten electrode, and using the resultant heat to create the joint.
