Laser welding robots can project a high-density laser beam onto two pieces of material, causing localized heating and melting, then cooling and solidifying into one piece.
Compared to traditional welding processes, laser welding robots have the following advantages and features:
1. Laser welding robots do not need to touch the parts being processed, so there is no external force acting on the welding components.
2. Laser welding robots concentrate a high amount of energy in their lasers, resulting in minimal heat impact and thermal deformation.
3. Laser welding robots can weld high melting point, hard-to-melt, and hard-to-weld metals such as titanium alloys, aluminum alloys, etc., and can achieve welding between certain dissimilar materials.
4. The welding process of laser welding robots does not pollute the environment, and welding can be done directly in the air, making the process simple and practical.
5. Laser welding robots produce small weld spots, narrow weld seams, and neat and appealing appearances, often requiring no post-weld treatment or only simple processing. The weld seam structure is uniform with fewer pores and defects, reducing and optimizing impurities in the parent material.
The mechanical strength of the weld is often higher than the mechanical strength of the parent material. The mechanical performance, corrosion resistance, and electromagnetic performance of laser welding robots are superior to conventional welding methods.
6. Lasers can be accurately controlled, with small focus points. Laser welding robots can be precisely positioned, achieving precision machining.
7. Laser welding robots are easy to integrate with computer numerical control systems or robotic arms and robots, achieving automatic welding and improving production efficiency.
8. Welding Robots Enhance Production Efficiency
Everyone understands that welding robots, with their short response times and rapid actions, can achieve welding speeds of 60-3000px/minute, a rate far surpassing traditional manual welding.
Unlike human welders who require breaks and are affected by factors such as mood, sick leaves, distractions, and overtime pay, welding robots can work continuously without interruptions, provided that the necessary conditions like water, electricity, and gas are met. This capability enables them to operate 24/7, thereby significantly elevating the company’s production efficiency.
9. Welding Robots Greatly Improve Product Quality
In the welding production process, operators only need to input welding parameters and motion trajectories, and the robot will precisely repeat these actions. Welding parameters like current, voltage, speed, and wire length play decisive roles in the welding outcome.
With welding robots, the parameters for each weld seam are constant, minimizing human-related inconsistencies and reducing the demand for skilled labor. Thus, the quality of robot welding is stable and reliable, effectively assuring the quality of the company’s products. In contrast, factors such as welding speed and wire elongation are uncontrollable in manual welding, making it challenging to maintain product quality uniformity.
10. Welding Robots Can Reduce Business Operating Costs
Welding robots mainly help reduce business operating costs in large-scale production lines, where one robot can replace 2-4 industrial workers. As welding robots don’t get tired and can operate continuously 24 hours a day, they greatly reduce the company’s labor costs.
11. Welding Robots Make the Company’s Production Planning More Efficient
Given the high repeatability of welding robots, which perform welding tasks faithfully according to the assigned parameters, their use allows for a clear and definite product production cycle and real-time control of product output.
Furthermore, the production rhythm of welding robots is fixed, making the planning of production schedules precise. Accurate production planning enables the maximization of the company’s production efficiency and resource utilization.
12. Welding Robots Can Shorten the Product Model Changeover Cycle
Welding robots can shorten the cycle of product model changeovers, significantly reducing corresponding equipment investments and enabling the automation of small batch product welding.
When updating product models, customers only need to redesign the corresponding welding fixtures; no changes to the robot body are necessary. A simple program command modification can accommodate product and equipment updates.
The use of welding robots for welding tasks liberates more labor, ensures employee health, reduces the frequency of work-related injuries, and brings numerous benefits to the steady development of the company.
Therefore, businesses adopt laser welding robots for their precision, efficiency, strength, and timeliness, ensuring quality, quantity, and delivery time. Currently, they have become a highly competitive processing method in the precision machining industry, widely used in industries such as machinery, electronics, batteries, aviation, instrumentation, etc., for spot welding, stack welding, and seal welding of workpieces with special requirements.
