Features of laser welding aluminum to steel


1. Multi-purpose machine, equipped with versatile nozzles for welding, cutting, cleaning, and other functions.

2. Independently developed handheld welding torch, equipped with various safety alarm devices, easy and flexible to operate.

3. The machine has multiple safety alarm functions. The welding copper nozzle's trigger switch is only effective when it touches the metal and securely clamps the metal sheet. The welding copper nozzle automatically locks the light after moving away from the workpiece. The machine has high safety to ensure absolute safety for operators during work.

4. Suntop's patented water circulation protection system and auxiliary gas detection effectively extend the service life of the laser lens and prevent damage to optical components caused by improper operation.

5. Comes with various welding copper nozzles, such as flat angle, inner angle, outer angle, etc. Different nozzles can be replaced according to different welding needs to meet various welding requirements.


Details of laser welding aluminum to steel

Advantages of laser welding aluminum to steel


● Handheld coal gun to replace the previous inherent light path, more flexible and convenient, to achieve long-distance emblem light welding, to overcome the limitations of the workbench travel space.
● Handheld welding head equipped with 5m-10M original optical fiber, flexible and convenient, can achieve outdoor welding.
● Handheld mode of operation, assembly of special welding nozzle can be realized on the workpiece any part of any angle of the welding.
● Beautiful weld, no weld scars, no discoloration, no need to follow up to play the rice: weld firmly, weld strength to reach or even exceed the base material itself: suitable for welding, stacked welding, inside and outside the Angle Welding, round rainbow welding, irregularly shaped coal, and so on.
● The whole set of equipment is highly functional and ergonomically designed, suitable for all kinds of working environment scenarios.
Specialized laser safety protection function, to protect the safety of the operator during the work.
● The operation is simple and easy to learn, the operator's technical threshold is not high, saving labor costs.


Use of laser welding aluminum to steel


With the continuous development of laser welding technology, laser welding machines are becoming more and more widely used.


Welding: The main welding objects of laser welding machines are metals, such as stainless steel, copper, aluminum, gold, silver, titanium, nickel, tin, chromium, niobium, carbon steel, mold steel, galvanized sheets, etc. It is suitable for flat, straight, Arc and arbitrary shape welding, welding work can be carried out from multiple angles to meet users' personalized welding needs.

Cutting: Welding and cutting are often inseparable. Laser welding machines combine the functions of the two. Laser welding machines can be used to laser cut metal materials, such as copper plates, aluminum plates, stainless steel plates, carbon steel plates, galvanized plates, etc. Meet the cutting needs of conventional thin plates.

Weld bead cleaning: It can effectively remove oxides, welding slag, oil, dust and other impurities produced during the welding process, making the weld surface clean. This not only helps improve the quality of the weld, but also enhances its strength and appearance. Laser cleaning is highly precise and controllable, thoroughly cleaning the weld surface without damaging the base material.
