The laser welding machine is an efficient and precise welding method that uses a high-energy density laser beam as a heat source. The welding process is of thermal conductivity type. Laser radiation heats the surface of the workpiece, and the surface heat diffuses into the interior through thermal conduction. By controlling the width, energy, peak power and repetition frequency of the laser pulse, the workpiece is melted to form a specific molten pool. The laser welding machine can effectively combine the molecular layers of the weld and realize the seamless joint of the weld. So what can the handheld fiber laser welder be used for and how does it works?
1. Automobile manufacturing industry.
The automobile industry is one of the main application areas of laser welding equipment. When a car is driving, it will be in close contact with the ground, and every component and structure is subjected to varying degrees of impact, which requires the overall structural density of the car to support. In the automotive industry, laser welding is usually used in key positions of body welding and parts with special requirements for the process. For example, it can be used to weld the roof and outer panels to solve the problems of welding strength, efficiency, appearance and sealing; Rear cover welding can solve the problem of right-angle lap joints; laser tailored welding for door assemblies can effectively improve welding quality and efficiency. Laser welding has the advantages of energy density, narrow heat-affected zone, high welding speed, easy automatic control, and no subsequent processing. The flexibility of laser welding machine meets the processing of various automotive materials, reduces automotive production costs, and improves production efficiency. Bring huge economic benefits to the automobile manufacturing industry.
2. Kitchenware industry
In order to make more beautiful stainless steel kitchenware and meet people's needs, the fiber laser welding machine adopts high-power continuous seamless welding, and the effect is better.The machine does not need any consumables, and the operation is simple and convenient. Laser welding machining technology is a non-contact processing method, so there is no mechanical extrusion or mechanical stress. The production of kitchen utensils has relatively high requirements for welding technology, and the traditional welding process is difficult to meet the high-precision production requirements. Compared with arc welding, the kitchenware laser welding machine saves about 80%-90% of electric energy, and the processing cost can be reduced by about 30%. It can weld dissimilar steel and dissimilar metals, and complete mechanization and automation easily. Fast speed, small deformation, small heat-affected zone, high and aspect ratio. The welding seam is beautiful, smooth, and has no air holes, and no treatment or simple treatment is required after welding. More and more home appliance companies are adopting laser welding technology.
3. Door and window guardrail processing industry
In the process of modern home improvement, there are more and more stainless steel materials, including some stainless steel doors, windows and guardrails. The stainless steel doors, windows and guardrails also need to be welded with welding equipment during the process.The handheld laser welder can greatly reduce the preparation of workpieces in the early stage of welding, and reduce the technical requirements for welding operators.We only need to adjust the welding parameters according to the thickness of stainless steel doors and windows. The hand-held laser welding machine has strong penetrating ability, the welding appearance is neat and beautiful, and the welding strength is better.
Senfeng handheld laser welding machine has six spot modes, which can better adapt to different workpiece processing requirements.
Point mode: refers to the state where the motor is not swinging, and the light spot is the smallest. Strong penetrating power, can be used for penetration welding, stitch welding, or thicker materials
Linear mode: refers to swing a motor, connect the dots into a line, adjust the width, and have a certain penetration force to thick plates. It is suitable for use in positive fillet welding, tailor welding, and wire feed welding.
Circular mode: It swings two motors to make the dot edges into a circle. The diameter can be adjusted. The energy density is evenly distributed. The advantage of using high frequency welding of thin plates is obvious. It can be used for welding thin plates with a minimum thickness of 0.3mm.
Laser head frequency: the higher the frequency, the faster the motor rotation speed.The spots are dense but the single-point energy is slightly weaker. It is suitable for thin plate welding and is not easy to penetrate the plate. The low-frequency motor rotates slowly, and the light spot outline shows clear and strong energy, which is suitable for thick plate welding.
Laser head width: The welding width ranges from 0.2 to 5mm. The welding width needs to be determined according to the size of the plate gap and the diameter of the welding wire. The larger the welding width, the larger the laser range,and the energy will be relatively dispersed.
