Micro TIG (GTAW) is a process of performing minute welding operations on intricate assemblies with minimal heat. Using an infusible electrode allows TIG welding to work great for metals only a few millimeters thick.

Other benefits of micro-welding include:

  • Reduced heat input 
  • Reduced warpage
  • Smaller weld size

Our innovative process provides infinite machine control to make the process efficient and repeatable. We will work closely with you to understand your needs and deliver the highest quality end product – within your time table.

Micro TIG can be used when welding these types of metals:

  • Alloys
  • Aluminum
  • Brass
  • Bronze
  • Hardened tool steels
  • Magnesium
  • Stainless steel
  • Titanium
  • 3-D printed alloys
Welder performs intricate micro weld on a small part

Micro GTAW is performed under a high-powered microscope. This process produces very stable low amperage welding, which means it minimizes warp stress and fatigue on the metal. This process can be incorporated into a multitude of applications within all of the markets that we serve. 

Advantages of Micro TIG:

  • Very versatile, GTAW can be used on most metals
  • When performed correctly, there are great results in producing high-quality products
  • Due to no splatter, Micro TIG is considered a cleaner welding option
  • Filler metal is not always needed
  • High-level of control

Disadvantages of Micro TIG:

  • Often takes longer to produce
  • Extremely difficult to automate and usually requires manual application
  • Compared to other options GTAW can be a more expensive process
  • Parts that come preassembled with plastic components are at risk of melting due to the heat of the weld
  • Parts with springs are at risk of losing spring tension due to the heat
