Automatic laser welding machine features-Suntop

Features of automatic laser welding machine

1. Adopt imported gold-plated laser cavity, 6KW double pulse xenon lamp. Wave current controllable switching power supply, high power. Pulse programmable and intelligent system management, industrial computer control (three-axis or four-axis). Configuration precision X and Y axes, two mobile platforms and high-increase elevators, can be manually and do focus. Customers can choose a rotary table (φ80mm or φ125mm).

2. CCD Monitor system and 3P water cooling system.

3. Powerful PC control, easy to program, debug and maintain. It can complete automatic or semi-automatic spot welding, butt welding, lap welding, sealing welding, and welding for complex plane straight lines, arcs and arbitrary trajectories.

4. The software adopts the IDE integrated working environment method. The main interface integrates graphic editing, operation monitoring, acquisition programming, and motion control. The layout is simple and professional, which can effectively improve work efficiency.

5. High aspect ratio, small weld width, small heat-affected zone, small deformation, fast welding speed, which is 5-10 times faster than that of YAG laser

6. Optional: galvanometer welding table/two-dimensional or multi-dimensional welding table/manipulator welding table.

Details of automatic laser welding machine

1. Fiber laser source

More stable and lower cost than YAG laser source. The life span exceeds 100,000 hours.

2. Laser welding head

The laser welding head can realize spot welding, butt welding, lap welding, sealing welding and other welding + aiming combination design for thin-walled materials and precision parts, visual CCD acquisition, integrated infrared sensor, and accurate positioning.

3. Motion axis

High positioning accuracy, sensitive response, shockproof design, no need to manually move the product, automatic movement for welding.

4. Solder joint monitoring

High-definition CCD display, better observation of the welding process, beautiful solder joints. Industrial computer, control system, welding special software, can guarantee the parameter set, multi-level waveform can be adjusted.

5. Water cooling system

The intelligent dual-temperature dual-control mode provides an effective solution for all-round temperature control of fiber lasers.

Advantages of automatic laser welding machine

1. Precisely and quickly weld complex parts, signs, metal letters, etc.

2. CCD camera monitoring system provides real-time display of welding effect.

3. 360° rotating welding, large welding range, flexible welding in difficult positions.

4. The elector-optical conversion rate is as high as 30%, which is 10 times that of YAG laser, and the energy consumption is extremely low.

5. Make the life as long as 100,000 hours, small size, light weight, maintenance-free.

6. The depth of the weld pool can reach up to 10mm, the weld seam is smooth and beautiful, and there is no need for post-welding treatment or only simple treatment procedures.

7. Suitable for 24h industrialized mass production.
