Basic Knowledge of Manual Laser Welding

1. What is laser welding?

Laser welding is a common welding technique in which the laser output from the laser is transmitted into the optical fiber through the coupling system, and then focused on the workpiece through the laser output system. Laser welding can be divided into manual laser welding and automatic laser welding according to the operation mode.

2. Specific application of manual laser welding

Today, most manual laser welding equipment uses fiber lasers. The laser achieves long-distance output through optical fiber, so it is more popular with users in terms of beam quality, light spot, energy loss and welding freedom. The equipment is streamlined, flexible to use, and the price is cheap. The focus is on the point where the welding function and process quality are better than the hard light path. The welding machine is more powerful, and some manual fiber laser welding machines adopt the new technology of swinging the laser welding head to realize the adjustment of various parameters such as the light spot, so the user does not need to worry that the distance between the workpieces is a little too large and the welding will be affected ( the welding can be achieved between general distance of 3-5MM). Therefore, manual laser welding can significantly improve the application function and scope of welding and reduce the difficulty of welding.

In addition, because the handheld fiber laser welding machine adopts fiber laser, it is easy to maintain, even without maintenance. As long as it is cleaned daily, there is no loss of consumables. Therefore, it is widely used in welding materials such as metal and thin plates, which solves the problem of cabinets, kitchens, toilets, stairs and elevators. A series of complicated and irregular welding process problems in industries such as, shelves, ovens, stainless steel doors and windows guardrails, distribution boxes, and stainless steel home furnishings.

Of course, manual laser welding is not a panacea. When operating different workpieces, you still need to refer to different requirements for selection.
