What are the differences between the hand-held fiber laser welding machine and the traditional argon arc welding machine? What are the advantages and application areas?

What is a hand-held fiber laser welding machine?​ The handheld optical fiber laser welding machine is a new generation of laser welding equipment, which belongs to non-contact welding. The operation process does not require pressurization. Its working principle is to directly irradiate the high-energy laser beam on the surface of the material. Through the interaction between the laser and the material, the material is melted inside and then cooled and crystallized to form welds. The handheld optical fiber laser welding machine fills the gap of handheld welding in the laser equipment industry and subverts the working mode of the traditional laser welding machine. The handheld laser welding machine replaces the previous fixed optical path, which is flexible, convenient and has a long welding distance, making it possible to operate laser welding outdoors. The hand-held welding of Linservice Industry is mainly aimed at laser welding of large workpieces at a long distance, overcoming the limitations of the travel space of the workbench. The heat affected area is small during welding, which will not lead to work deformation, blackening, and traces on the back. Moreover, the welding depth is large, the welding is firm, and the dissolution is sufficient, which can not only realize thermal conduction welding, but also continuous deep penetration welding, spot welding, butt welding, overlap welding, seal welding, seam welding, etc. This process subverts the working mode of the traditional laser welding machine, and has the advantages of simple operation, beautiful weld, fast welding speed and no consumables. It can weld thin stainless steel plate, iron plate, galvanized plate and other metal materials, and can perfectly replace the traditional argon arc welding, stainless steel plate, iron plate, aluminum plate and other metal materials.

Advantages of Chengdu Linservice handheld laser welding machine: 

1. Wide welding range: The handheld welding head is equipped with 5m-10M original optical fiber, which overcomes the limitations of workbench space and can be used for outdoor welding and long-distance welding;

2.​ Convenient and flexible to use: the hand-held laser welding is equipped with a mobile pulley, which is comfortable to grip, and can adjust the station at any time without the need for a fixed station. It is free and flexible, and suitable for various working environment scenarios.

3.​ Multiple welding methods: It can achieve welding at any angle: overlap welding, butt welding, vertical welding, flat corner welding, internal corner welding, external corner welding, etc. It can weld workpieces with various complex welds and irregular shapes of larger workpieces. Realize welding at any angle. In addition, he can also complete cutting and freely switch between welding and cutting, simply changing the welding copper nozzle to a cutting copper nozzle, which is very convenient.

4. Good welding effect: handheld laser welding is hot fusion welding. Compared with traditional welding, laser welding has a higher energy density, which can achieve better welding effect. The welding area has small thermal impact, is not easy to deform, blackens, and has traces on the back. The welding depth is large, the melting is full, firm and reliable, and the weld strength reaches or even exceeds the base metal itself, which cannot be guaranteed by ordinary welding machines.

5.​ Welding seams do not require polishing: After traditional welding, the welding points need to be polished to ensure smoothness and roughness. Chengdu Linservice handheld laser welding just reflects more advantages in processing effect: continuous welding, smooth without scale lines, beautiful without scars, and less follow-up polishing process.

6.​ Welding without consumables: In the impression of most people, the welding operation is "left hand goggles, right hand welding wire clamp". However, the handheld laser welding machine can easily complete welding, which further reduces the material cost in production and processing.

7.​ It has multiple safety alarms, and the welding nozzle is only effective when touching metal by touching the switch. After removing the workpiece, it automatically locks the light, and the touch switch is equipped with temperature sensing. High safety, ensuring the safety of operators during work.

8. Labor cost saving: compared with Arc welding, the processing cost can be reduced by about 30%. The operation is simple, easy to learn, and quick to get started. The technical threshold for operators is not high, and ordinary workers can take up their positions after brief training, which can easily achieve high-quality welding effects.

Comparison between hand-held laser welding machine and argon arc welding:

1. Comparison of energy consumption: compared with traditional Arc welding, Chengdu Linservice can save about 80%~90% of electric energy by handheld laser welding machine, and reduce about 30% of processing cost.

2. Comparison of welding effects: Linservice Industrial Laser handheld welding can complete the welding of dissimilar steels and metals. Fast speed, small deformation, and small heat affected zone. The weld seam is beautiful, flat, without/with few pores, and without pollution. The hand-held laser welding machine can carry out micro-opening parts and precision welding.

3. Comparison of subsequent processes: Linservice Industrial Laser handheld welding has low heat input, small workpiece deformation, and can obtain a beautiful welding surface without or only requiring simple treatment (depending on the requirements of the welding surface effect). The hand-held laser welding machine can greatly reduce the labor cost of huge polishing and leveling processes.

Application field of Chengdu Linservice industrial hand-held laser welding machine: mainly for large and medium-sized sheet metal, cabinet, chassis, aluminum alloy door and window frame, stainless steel washbasin and other large workpieces in fixed positions such as inner right angle, outer right angle, plane weld welding. When welding, the heat affected area is small, the deformation is small, the welding depth is large, and the welding is firm. Widely used in the kitchen and bathroom industry, home appliance industry, advertising industry, mold industry, stainless steel product industry, stainless steel engineering industry, door and window industry, handicraft industry, home appliance industry, furniture industry, automotive parts industry, etc.
