What Is Micro Welding?

Welding is a key process in modern industrial production, and nowadays, with the demand for smaller, more precise, and more complex products in ever-increasing quantities—micro welding has become an essential tool. Did you know that the welding industry is expected to hit $1

6 billion by 2022? Or that micro welds, despite being incredibly small and delicate, are capable of achieving incredible strength in the right applications? Join us as we uncover the exciting world of micro welding: what it is, how it works, and where it excels.

What is Micro Welding?

Micro welding is an advanced technique for welding two pieces of metal together at extremely small scales. It is mainly used for repairing or assembling very tiny or microscopic parts that are difficult to access or maneuver with traditional welding techniques.

Micro welding is also known as nano-welding because it involves welding components at a microscopic level.

Applications of Micro Welding

Micro welding is used in a variety of industries, including aerospace, medical, automotive, and electronics.

It can be used for applications such as:

  • Welding components on circuit boards or micro-electronic devices
  • Repairing or assembling precision mechanical parts
  • Joining gold and silver interconnects
  • Welding very small medical parts
  • Making miniature motors, engines, and valves
  • Constructing implants and prostheses
  • Creating micro fuel cells and storage devices

Advantages of Micro Welding

Micro welding offers several advantages over traditional welding techniques. These include:
  • Enhanced accuracy due to precise control of the welding process
  • Minimized heat stress on components
  • Faster join formation
  • Reduced cycle times
  • High quality welds without defects

Types of Micro Welding

There are several types of micro welding, each suited to different applications.

These include:

  • Resistance welding: This technique uses an electric current to weld two metals together at very small scales. It is a popular choice for assembling circuit boards and micro components.
  • Laser welding: This technique uses a high-power laser to weld components together at a microscopic level.

    It is very precise and can be used for a variety of materials, including metals and plastics.

  • Ultrasonic welding: This technique uses high-frequency vibrations to weld two components together. It is best suited for small assemblies and is commonly used in the manufacturing of medical devices.


Micro welding is a specialized welding process that is used to assemble very small components. It is an accurate, precise, and reliable technique that offers several advantages over traditional welding methods.

As technology advances, micro welding is becoming an increasingly popular choice for creating complex components and structures at a microscopic level.
