Micro TIG Welding
Micro TIG welding is a very precisely controlled welding process for welding parts that cannot be welded with normal TIG welding due to heat input and warping. As the name implies, it is performed under a microscope. In micro TIG welding, specialized power supplies are used due to their ability to go down to 1/10 of an amp with a stable arc. Micro TIG welding also utilizes filler wires ranging from .005" to .035". Intricate welds can be preformed with this process while depositing very precise amounts of weld material. Weld buildups can be as small as .005".
Due to the lower heat input, micro TIG welding introduces less stress into the part. This is useful for many applications which produce delicate or intricately engineered parts. Likewise, micro TIG welding is the process of choice when an engineering change is in order. Changes in shapes, sizes and geometries can be made in a time-saving and cost-efficient manner compared to inserting or remaking an entire cavity or die section.
