Professional solutions

Solution: ST-OLW Online Laser Welding Machine

Power: 12000W

Result: After rigorous testing and acceptance, the customer purchased 6 sets of ST-OLW serie online laser welding machines at one time. After using online laser welding, we helped customers solve the problem of producing new products that could not be produced by traditional high-frequency welding methods.

Introduction to online laser welding technology

Online laser welding is an efficient and precise welding method that uses a high-energy laser beam to directly act on the surface of the material, causing the material to melt and solidify rapidly to form a strong weld.

Whether it is a traditional oil vehicle or a new energy vehicle, in the current environment of cost reduction, efficiency improvement and efficient production, metal profiles such as automobile exhaust pipes and battery trays are widely used in one-piece online laser welding.

Laser, as a new type of non-contact welding method, has greatly improved production efficiency and process intensity.

Advantages of online laser welding technology

1. High efficiency: The speed of laser welding far exceeds that of traditional welding methods, greatly improving the work efficiency of the production line.

2. High quality: Laser welding can achieve precise control, high weld quality, and greatly reduce subsequent repair work.

3. Low thermal impact: The heat affected area of laser welding is small, which reduces the thermal deformation of the material and ensures the dimensional accuracy of the product.

4. Strong material adaptability: Laser welding is suitable for a variety of materials, including carbon steel, stainless steel, aluminum alloy, etc., to meet the needs of different pipe materials.

5. Environmentally friendly: Compared with traditional welding, laser welding produces less exhaust gas and noise, and is more environmentally friendly.
