Micro TIG Welding

What Is Micro TIG Welding?

Micro TIG welding (micro tungsten inert gas), also known as pulse arc welding, is an arc welding process that utilizes a constant current welding power supply and a non-consumable tungsten electrode to generate arcs between the workpiece and the tungsten electrode and using the resultant heat to create the joint.

What are Common Applications of Micro-TIG Welding?

Micro TIG processes focus on welding small parts of area 5 mm x 5 that require high weld integrity, such as:

  • Medical device assemblies
  • Aerospace components
  • Precision electronics
  • Instrument and sensor fabrication

In these applications, weld consistency, feature fidelity, and controlled heat input are essential for product performance and reliability.

Advantages of Micro-TIG Welding

Pulsed arc welding has many advantages:

  • Solder-free process
  • Highly durable welds, especially when exposed to vibration or heat
  • Widely applicable for joining high melting point metals, dissimilar metals, and even thin magnet wires of φ0.02mm.
