Micro GTAW Welding Services

Micro GTAW

Superior Joining Technologies, Inc. (SJTI) provides micro precision TIG welding services. This process can be used in multiple applications within aerospace, medical, laboratory, and commercial projects. With over 25 years of experience our team is capable of running prototypes to production quantities for your company. 

Superior Joining Technologies, Inc. has the experience and expertise to perform the most microscopic of welds using our Micro TIG Welding Services. We have a fully equipped welding lab dedicated to micro-weld production and design modifications.

Microscopic Tungsten Inert Gas (TIG) Welding uses a Microscope with 40X magnification and a specialized microscopic TIG torch that allows micro precision. The filler material wires used in this process can go down to .005”. At Superior Joining, pre-heating is always provided as part of the Micro GTAW welding services to help prevent cracking. Additionally, we keep filler materials in stock to match the base metal material quickly with no time lost on material orders.

Is Micro TIG Welding Right for You?

At Superior Joining Technologies, Inc, we help our customers determine if their projects are the right fit for micro TIG welding. This welding process is ideal for small, intricate welds that cannot be performed using normal TIG welding processes.

Micro TIG welding is also useful in areas where the risk of warping in the heat affected zone must be reduced. This is accomplished with low amperage inputs and small diameter wires.

Micro TIG Welding Advantages

  • Achieve a deeper penetration
  • Reach difficult areas
  • Durable and discrete welds
  • Lower cost than remaking the damaged part
  • Faster and less expensive than laser welding
  • Welds as small as .010 means less machining is needed.

Micro TIG Welding Applications

Micro-weld repair can be used on a variety of applications. A popular use for Micro TIG welding is the repair of detailed features on plastic injection and die cast molds. Other applications include:

SJTI provides a welding service of repairing minute-detailed features on plastic injection and die-cast molds. We are using a Miller Maxsta. In addition to micro GTAW welding, we also offer manual GTAW and longitudinal seam GTAW weldingr 152 inverter welding power source with a modified 5240 Olympus stereo microscope. These key components are supported by a fully equipped welding lab dedicated to micro-weld repair. This enables our staff to perform intricate build-up operations that allow the customer to recover valuable time and expense. Repairs of this type are typically a result of design modifications or machining error. Micro-weld deposits are readily machined to leave no evidence of the weld operation. We keep a full inventory of tool-steel filler materials in stock in a variety of sizes for a wide spectrum of applications.
