Principle of laser jewelry spot welding machine

Laser jewelry spot welding machine uses laser beam as a heat source to locally heat materials in small areas through high-energy laser pulses. The energy of laser radiation diffuses into the interior of the material through thermal conduction, causing the material to melt and form a specific molten pool.

working principle

The working principle of laser jewelry spot welding machine mainly includes the following steps:

Laser radiation heating: The laser beam is irradiated onto the surface of the workpiece, and the material is locally heated in small areas through high-energy laser pulses.

Heat conduction: Surface heat is conducted through heat conduction to diffuse inside the material, causing the entire welding area to melt.

Parameter control: By controlling the width, energy, peak power, and repetition frequency of laser pulses, the welding process is precisely controlled to form a specific molten pool.

Application scenarios and advantages

Laser jewelry spot welding machines are widely used in the processing of gold and silver jewelry and the welding of micro and small parts. Its advantages include:

High precision: capable of precise control of welding position and size, suitable for fine machining.

Low loss: During the welding process, there is no damage to the internal structure of the workpiece, ensuring its integrity.

Aesthetic: The protective gas output prevents oxidation and discoloration of solder joints, ensuring their aesthetic appearance.

Efficient: Fast welding speed, suitable for mass production, and can work continuously for 24 hours with stable performance
