Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to a movable laser welding device. Background Art

[0002] Laser welding is an efficient and precise welding method that uses a high energy density laser beam as a heat source. Laser welding is one of the important aspects of the application of laser material processing technology.

[0003] Laser welding of CVD products is often used to repair defects such as pits, bumps, and bruises on the surface of products. However, traditional equipment is a fixed welding device, which requires manual alignment of the points on the product that need to be welded with the laser welding head for welding. This greatly increases the labor intensity of the operators. In addition, this welding method can easily cause serious damage to the product surface during the welding process, affect the chemical composition of the product's base material, and even directly cause a series of serious quality problems such as product scrapping. In addition, laser welding cannot be performed on large-sized or special-shaped products.

The welding device can be placed on products of any size for operation. It can be free and not affected by spatial environmental factors and can perform laser welding operations at any angle, thereby avoiding errors during operation that lead to a high defective rate of laser welded products and a series of other problems.
