The term “micro-welding” describes any welding that is smaller than a typical weld. Numerous methods are available for completing it, including TIG welding, thermo compression welding, and precise spot resistance welding. Micro TIG procedures aim to weld tiny, 5 mm by 5 mm pieces together, usually fragile parts from the electronics, medical, or automotive industries. 

Its benefits are numerous. For instance, the technique requires no solder, and the finished weld is exceptionally resilient to heat and vibration. Furthermore, pulsed micro TIG welding extensively combines metals with high melting points, dissimilar metals, and even thin magnet wires with a diameter of φ0.02mm.

micro TIG welding and its applications.

Micro TIG Welding in a Nutshell 

Micro TIG welding is an exceptionally carefully regulated technique for objects that cannot be welded with traditional TIG welding because of heat input and warping. As the name suggests, it’s done under a microscope. It uses a constant current welding power supply to create arcs between the workpiece and the tungsten electrode. The heat created forms the joint, producing high-quality welds with few heat-affected zones.

Filler wires with a diameter of.005-.035 inches are also used in micro TIG welding. This procedure allows for the exact deposit of weld material while producing intricate welds. Weld build-ups may be as little as .05 inches in size.

Benefits of Micro TIG Welding 

High Quality 

Micro TIG welding enables accuracy in producing intricate parts. It is ideal for finishing precise welds on small objects because the small, mild arc permits constant welding over brief periods. Product damage will likely occur rather than a high-quality weld if alternative welding techniques are applied to these intricate things.

The Ability to Weld Confined Areas 

One of the most evident advantages of micro TIG welding is its capacity to weld in tiny spaces. Micro TIG welding equipment can work in 0.2 mm to 5 mm increments, which means that, in contrast to standard welding equipment, it can make welds in joints and other small places. It can also be applied to objects, like tiny wires, that are too small for other welding processes to finish efficiently but are not in a restricted location.

Cost Saving 

Welding tiny items is incredibly economical with micro TIG welding. Micro Weld engineers can operate an effective, profitable business because of the high quality of their job and the speedy outcomes. Clients can receive final product assembly sooner due to the tasks’ faster completion, resulting in satisfied and repeat business for you.


Applications for Micro TIG Welding 

Micro TIG welding is commonly used to rebuild intricate details of plastic injection and die-cast molds. Additional uses include the following:

  • Connectors and electronic devices
  • Intricate fabrications and assemblies
  • Commercial ventures
  • Medical equipment 
  • Miniature assemblies
  • Welding of firearms 
  • Dental
  • Tool assemblies 

Thanks to the reduced heat input, Micro TIG welding adds less stress to the part. Numerous applications that create finely designed or sensitive parts can benefit from this. 

Wrapping up

Micro TIG welding produces high-quality parts that can withstand heat and vibration. Typical applications for this kind of welding include the medical, aerospace, military, and consumer markets for items like surgical instruments, eyewear, high-performance products, etc.
