Advantages of the product

Industrial-Grade Fiber Laser Sources Ensure Deep Penetration and High-Speed Welding Across Diverse Metal Alloys

Utilizing advanced fiber laser technology, these machines provide high power density for deep penetration with a narrow heat-affected zone, drastically reducing thermal distortion and post-processing needs. Welding speeds reach up to 10 meters per minute on thin materials while maintaining integrity on reflective metals like aluminum and copper. Photoelectric conversion efficiency exceeds 30%, lowering energy consumption in high-volume production. The long-life diode-pumped source ensures stable power output for tens of thousands of hours, eliminating downtime associated with traditional lamp or crystal replacement. This robust performance is critical for industries requiring consistent seam quality in automotive components, battery trays, and precision medical device housings where reliability and repeatability are non-negotiable manufacturing metrics.

Superior Beam Delivery with Galvanometer Scanner Options for Remote Welding and High Throughput Applications

Optional 2D and 3D galvanometer scanning heads utilize rapidly tilting mirrors to position the beam, eliminating physical head travel and reducing idle time between weld spots by up to 80%. This remote welding technique executes hundreds of stitch welds per minute on large components like automotive seat frames or heat exchanger plates. The scan field covers up to 200mm x 200mm while software compensates for optical path variations to maintain consistent spot size and focus depth. This technology is particularly effective for welding copper hairpins in electric motor stators, where minimal spatter prevents electrical shorts. High throughput capability directly enhances manufacturing return on investment under tight takt time constraints, making it ideal for high-volume production environments.

Tianchen Laser provides professional laser welding machines for stainless steel welding, which are designed for the physical and chemical properties of stainless steel materials such as good corrosion resistance, high thermal conductivity and easy deformation during heating, and are widely used in stainless steel processing scenarios in kitchenware manufacturing, medical equipment, architectural decoration, food machinery, auto parts and other industries. Stainless steel is a common metal material in industrial production and daily life, and its welding quality directly affects the appearance, strength and service life of products. Traditional welding methods are prone to problems such as large heat-affected zone, serious deformation, oxidation and blackening on the welding surface when welding stainless steel, while our special laser welding machine for stainless steel uses high-energy laser beam as the heat source, which can realize concentrated heating, fast welding speed, small heat input, effectively reducing the deformation and thermal oxidation of stainless steel workpieces, and the weld seam is smooth, firm, beautiful, without obvious welding marks, and can well retain the corrosion resistance of stainless steel. Our equipment supports the welding of various types of stainless steel such as 304, 316, 201, etc., and is suitable for thin plate welding, precision parts welding, pipe welding, sheet metal splicing and other processing forms of stainless steel. In the kitchenware industry, for example, our laser welding machines are used in the production of stainless steel sinks, tableware and kitchen utensils, which can realize seamless welding of complex shapes, improve the sealing and aesthetic appearance of products, and meet the hygiene and durability requirements of kitchenware products; in the medical equipment industry, the equipment is used for welding stainless steel parts of medical devices, ensuring the cleanliness, structural stability and safety of medical devices, and complying with the strict standards of the medical industry; in the field of architectural decoration, it is used for welding stainless steel profiles, handrails and decorative parts, ensuring the structural firmness while maintaining the metallic texture and aesthetic effect of stainless steel. Relying on the company's intelligent manufacturing base and mature production technology, the stainless steel laser welding machines we provide have stable performance, easy operation, high welding efficiency, and can meet the needs of small-batch customized processing and large-scale industrial production. At the same time, we can customize relevant parameters and supporting fixtures according to the thickness, shape and processing technology of customers' stainless steel workpieces to provide the most suitable welding solutions for stainless steel processing.

Common problem

How does fiber laser welding compare to traditional TIG or MIG welding?

Laser welding offers significantly higher speed, up to 10 meters per minute on thin materials, versus inches per minute with TIG. The heat-affected zone (HAZ) is 60-80% smaller, resulting in minimal part distortion and eliminating the need for post-weld straightening. Laser welding often produces a clean, narrow seam that requires no grinding or filler metal, reducing consumable costs and labor. However, it requires tighter part fit-up tolerances than MIG welding.

Can a laser welding machine be integrated with a robotic arm?

Yes, the laser welding source is designed for seamless integration with 6-axis industrial robots via standard communication protocols. The lightweight fiber optic cable routes easily through the robot dress pack. This configuration allows for complex 3D path welding on large stamped automotive parts, furniture frames, and kitchen equipment. Robotic integration provides flexibility for part changeover and maximizes the utilization of the laser power source.

How does wobble welding improve the quality of laser welds?

Wobble welding uses high-frequency oscillation of the laser spot to widen the melt pool and bridge gaps up to 0.3mm. This reduces the need for perfect part fit-up. The agitation helps gas escape from the weld pool, drastically reducing porosity in aluminum and copper welds. It also creates a smoother, aesthetically pleasing "stack of dimes" appearance and increases the effective weld width, making the joint less sensitive to misalignment during assembly.

Exceptional Stability and Minimal Maintenance Over 18 Months of Continuous Operation

We run this machine two shifts a day in our automotive components division welding sensor housings. Since installation, we have only changed the protective lens a few times and topped off the chiller. The power output remains steady at 2000W without any noticeable degradation. Remote support from the technician has been prompt whenever we had a programming question.

Robotic Laser Welding Cell Solved Our Copper Busbar Porosity Challenges

Welding thick copper busbars for switchgear was a nightmare with resistance welding. The laser machine with wobble function eliminated 99% of the porosity issues we had previously. The integration with our Fanuc robot was straightforward and the open communication protocol made I/O mapping simple. Our electrical conductivity test results are now best in class.
