In the past 3 months, we have received many customers' questions about the comparison between laser welding and traditional welding. Perhaps you have the same question. Is laser welding really a "more advanced" choice? Today we use 3 customer on-site cases to make a real comparison. Is it suitable for your production line?
1. Different welding principles determine the application scenarios:
Traditional welding (such as TIG/MIG welding) melts the welding material through arc, with a large heat-affected zone and molten pool control relying on experience. Laser welding uses a high-energy laser beam to instantly melt the welding zone, with an extremely narrow weld and a small heat-affected zone, which is suitable for high-precision and high-efficiency scenarios.
Stainless steel kitchenware manufacturer (from Vietnam):
"We used to weld stainless steel pots with argon arc welding, which required two skilled welders per shift. The efficiency was low, the welds were black, and the post-grinding time was long. After switching to handheld fiber laser welding machine, not only did the welds become more beautiful, but grinding was basically not required. One person could complete the welding task, and the daily production capacity increased by more than 40%. Laser welding is perfect for factories like ours that weld thin plates in batches."
Poland new energy vehicle battery shell factory:
"In the spot welding stage of the battery box, we used resistance welding before, and the welds were unstable, and sometimes there were cold welds or overheating deformation. After trying laser welding, the consistency of the welds was greatly improved, and the heat-affected zone was extremely small, there was no deformation problem, and the airtightness after welding also passed the strict test standards. Now we have fully replaced the laser welding system."
Mexican customer: elevator door panel processing company Industry：
"Our products have extremely high requirements for appearance. Traditional carbon dioxide welding always produces spatter and weld deformation, and often requires repair welding and polishing, which increases manpower and time costs. After switching to laser welding, the weld is thin and smooth, and almost no welding marks can be seen. The overall aesthetics of the product has been significantly improved, and the rework rate has dropped by more than half."
2. Operation experience: Laser welding is no longer "high-cold"
Many people worry that laser welding is "complex to operate". In fact, the current handheld fiber laser welding machine is very friendly:
Integrated design, plug and play;
handheld fiber laser welding machine adopts humanized interface and preset parameters;
Lightweight welding gun, 2 hours of training can be used;
Supports multiple welding methods (spot welding, stack welding, continuous welding);
Compared with traditional welding, which requires experienced masters to operate, handheld fiber laser welding machine lower the threshold for employment and are one of the solutions to the problem of "difficulty in recruiting welders".
Laser welding does not "replace" traditional welding, but is a better choice in high-precision and high-efficiency scenarios. If you also want to know whether your welding scene is suitable for laser welding, please contact us for material test welding evaluation.
