Description

Technical Field

[0001] The invention relates to the technical field of laser welding, and in particular to a tooling platform for laser welding processing. Background Art

[0002] Laser welding is an efficient and precise welding method that uses a high-energy-density laser beam as a heat source. In the 1970s, it was mainly used for welding thin-walled materials and low-speed welding. The welding process is a heat conduction type, that is, the laser radiation heats the surface of the workpiece, and the surface heat diffuses to the inside through heat conduction. By controlling the width, energy, peak power and repetition frequency of the laser pulse, the workpiece is melted to form a specific molten pool. Due to its unique advantages, it has been successfully applied to the precision welding of micro and small parts.

In addition, high-temperature welding will produce harmful waste gases such as metal vapor, nitric oxide, and nitrogen dioxide. These waste gases will directly drift into the air and cause damage to the human body after being inhaled. Therefore, in view of the above situation, it is urgent to develop a laser welding processing tooling platform that is convenient for weakening the glare light during welding, preventing the strong light from hurting the human eyes, and convenient for absorbing and purifying the harmful waste gas generated during welding, and reducing the damage caused by the waste gas being inhaled by the human body, so as to overcome the shortcomings in current practical applications and meet current needs.
