Mold laser welding machining principle


The principle of laser processing: the laser emitted by the laser generator passes through a series of processing, and the energy is highly concentrated in a small range after the lens focus. If the processed material absorbs the laser well, the material in the irradiated area will quickly heat up because of absorbing the energy absorption of the laser. Depending on the properties of the material (such as melting point, boiling point, the temperature causing chemical changes), the workpiece will undergo a series of physical or chemical changes, such as melting, gasification, generation of oxides, discoloration, and so on. This is the principle of laser processing.



Advanced processing mode, high efficiency


Compared with the traditional machining, the focused laser is like a very fine invisible tool, which "burns" the surface of the local area of the object point by point. It is characterized by no contact with the workpiece, no mechanical extrusion or mechanical stress, so it does not change the physical properties of the processed articles; because the size of the laser focusing is small, the thermal influence area is small, and the processing is fine, some conventional processes can be completed.

Applied range


TFL-400 mold laser welding machine is a high-power laser welding machine independently developed by Tongfa Laser Company. It uses the second-generation precision double-lamp power supply independently developed by Tongfa to pump and drive the power supply with touch screen, and the operation is more convenient. The main engine has laser head hand lifting and work table button electric lifting to achieve laser welding of different thickness molds. This model is more suitable for all kinds of high-power, large-area laser repair mold. Due to high laser power, laser welding beryllium copper mold, aluminum mold or aluminum parts. In a large area of the laser repair mold, you can use a thicker welding wire, the laser welding efficiency is greatly improved.

Attachment and consumables


Open hair mold laser welding machine protection lens
Description of accessories: During the use of the mold laser welding machine, there will often be the phenomenon of iron splashing on the laser lens when melting. The lens plays a role in protecting the internal focusing lens. If there is too much iron adhesion to the protective lens affecting the laser power, the lens needs to be replaced.

Mold laser welding machine welding wire pen
Parts description: this laser wire pen with a lock, can lock the 0.3-0.6 welding wire, especially for the case of deep hole and deep groove is not easy to hold the welding wire welding, welding wire pen plays a role in stable wire, is an indispensable tool for mold laser repair.

Mold laser welder foot switch

Description of accessories: in the use of laser welding machine, according to different situations, will continuously step, put the laser control foot, long time use will cause the aging or failure of the foot switch, found failure, consider replacing the foot switch.
