The minimum weld size and the ability to control the heat affected zone (HAZ) during welding depend on the welding process and equipment. The following are common welding processes:
1. Laser welding
Minimum welding point: The diameter of laser welded welding points can be as small as tens of micrometers (such as 20-50 micrometers), suitable for precision welding.
Heat affected zone: The heat affected zone of laser welding is usually small and can be controlled within 0.1mm, especially suitable for precision welding.
2. Electron beam welding
Minimum welding point: The diameter of the welding point for electron beam welding can be as small as tens of micrometers, suitable for high-precision welding.
Heat affected zone: The heat affected zone is extremely small and can usually be controlled within 0.1mm, making it suitable for precision machining.
3. Micro arc welding
Minimum welding point: The diameter of the welding point can be as small as several hundred microns, suitable for welding small parts.
Heat affected zone: The heat affected zone is relatively small, but usually slightly larger than laser and electron beam welding, and may be close to or slightly larger than 0.1mm.
4. Resistance spot welding
Minimum welding point: The diameter of the welding point is usually a few millimeters, which is not suitable for precision welding.
Heat affected zone: The heat affected zone is relatively large and difficult to control within 0.1mm.
5. Ultrasonic welding
Minimum solder joint: The solder joint size can be as small as a few hundred microns, suitable for welding small parts.
Heat affected zone: The heat affected zone is relatively small and can usually be controlled within 0.1mm.
Summary:
Minimum solder joint: Laser and electron beam welding can achieve solder joints of tens of micrometers.
Heat affected zone: Laser, electron beam, and ultrasonic welding can usually control the heat affected zone within 0.1mm, which is suitable for precision welding.
