What Is Laser Welding?

Laser welding is a process that utilizes a high-intensity laser beam as a heat source, and by focusing the laser energy on the joint part of the welded material, it causes the material to heat up and melt locally rapidly, and finally forms a welded connection. Laser welding is characterized by high precision, high speed and strong targeting, and is suitable for welding different materials and complex structures.

The concept of laser welding began in the 1960s, and with the rapid development of laser technology, laser welding gradually moved from laboratory research to industrial applications. Initially, laser welding was mainly used in aerospace and military fields. With the reduction of technology cost and the improvement of equipment performance, laser welding began to be widely used in many fields such as automobile manufacturing, electronics industry and medical devices. Today, laser welding has become an indispensable welding technology in modern manufacturing.

Working principle of laser welding

Laser welding is a welding technology that uses a high-energy laser beam to heat the workpiece to a molten state, thereby realizing the material connection. Its working principle can be summarized in the following key steps:

Laser generation and emission:

Laser welding uses specific types of lasers (e.g., fiber lasers, carbon dioxide lasers, etc.) to generate a high-intensity laser beam. The laser converts electrical energy into light energy and produces the laser light at a preset wavelength.

Beam Focusing:

The laser beam from the laser is focused by an optical system (e.g., a lens) to create a small, high-energy-density spot at a specific location in the welded joint. The diameter of this focusing point is typically between a few micrometers and a few millimeters.

Heating and melting:

When the laser beam is focused on the weld area, the light energy is rapidly converted to heat, causing the surface temperature of the material to rise rapidly until it reaches the melting point. At this point the material begins to melt, forming a molten pool.

Formation of the molten pool:

Under the action of the laser, the resulting molten pool forms a localized area of liquid metal at the location of the welded joint. The beam energy of the laser controls the size and depth of the molten pool, which affects the quality of the weld.

Curing and molding:

After the laser is fired, when the welding process is over, the molten pool begins to cool and solidify without external interference (e.g., airflow, etc.), resulting in a welded joint of high strength.

Control of Welding Parameters:

Critical parameters in the laser welding process include laser power, welding speed, focus position and gas protection. Optimization of these parameters can affect the quality, depth and solidity of the weld.

Laser welding, as an advanced welding technology, utilizes a high-energy laser focused on the material to achieve efficient and precise welding. Its working principle relies on the concentrated heating of the laser and the rapid solidification of the molten material, which is capable of handling a wide range of materials and is widely used in industrial manufacturing. Through good control of the welding parameters, high quality welded joints can be realized to meet the needs of different fields.
