Introduction

 

Laser welding is a welding method that uses a focused laser beam as an energy source to bombard the weldment with the generated heat. Because the laser has optical properties such as refraction and focusing, so laser welding is very suitable for welding of micro-parts and parts with poor weld ability. Laser welding has the characteristics of low heat input, small welding deformation, and is not affected by electromagnetic fields. The welding process is of thermal conductivity type, that is, the surface of the workpiece is heated by laser radiation, and the surface heat is diffused to the inside through heat conduction. By controlling the laser power, swing width, frequency and other parameters, the workpiece is melted to form a specific molten pool.

Advantages of fiber laser welding

 

1.The heat input can be reduced to the minimum required amount, the metallographic change range of the heat-affected zone is small, and the deformation caused by heat conduction is also the lowest.

2.There is no need to use electrodes, and there is no concern about electrode contamination or damage. And because it is not a contact welding process, the wear and deformation of the machine tool can be minimized.

3.The laser beam can be focused on a small area and can weld small and closely spaced parts.

4.A wide range of materials that can be welded, and can also join various different materials.

5.Easy to weld at high speed automatically, and can also be controlled by digital or computer.

6.When welding thin materials or small diameter wires, it will not be as easy to be troublesome as arc welding.

7.Unaffected by magnetic field (arc welding and electron beam welding can be affected easily), can accurately align the weldment.

8.Two metals with different physical properties (such as different resistance) can be welded.

 

Other advantages

 

1.Labor cost

Labor cost of argon arc welding: argon arc welding requires a mature welder. The monthly salary of a mature welder starts at 8K. The labor cost for a year is 8k*12=9.6w

Hand-held welding labor cost: Hand-held welding is simple and easy to learn. Ordinary operators can learn it within 1-2 days. The monthly salary of ordinary operators is generally about 4k, and the labor cost for a year is 4k*12=4.8w; so In terms of labor costs alone, replacing argon arc welding with handheld welding can save 4.8w of wages per worker per year.

Argon arc welding welders are "difficult to recruit" and require extremely high experience and skill requirements for welders. Laser welding can also be operated by non-professional personnel. "Getting started and welding" has become a unique advantage of laser welding. Moreover, as labor wages have increased year by year, this has further increased the labor costs of enterprises. The cost of a professional welding worker and a general worker has generally reached a gap of 2-3 times.

2.   Deformation

The heat of the laser welding machine is more concentrated, and the thermal deformation caused by the material is small. The heat-affected zone of laser welding is only one-tenth of that of argon arc welding. When the thin plate is fully welded, the deformation is also the smallest.

3.   Welding quality

Laser welding machines have more advantages in welding thin-walled materials. In terms of accuracy, the laser welding machine has higher precision, and the laser welding machine is more beautiful. The subsequent welding basically does not need to be polished, which reduces a process, and saves time and trouble and saves the cost of polishing.

4.Welding speed

For a mature argon arc welding worker, we assume that he can weld 10 products in an hour. We conservatively estimate the speed of laser hand-held welding. At least 20 products can be welded in one hour; it is equivalent to the capacity of two argon arc welding workers. The annual salary of 2 argon arc welding workers is 19.2 watts; one hand-held welder’s annual salary is 4.8 watts; the saved salary is 14.4 watts.

Q:Does the frequency of the laser welding machine affect the lifetime of the optical fiber?
If the frequency is large, the energy per unit time will rise. If the light is a little bit bad, it will burn easily for a long time
Q:Is laser welding machine universal with laser cutting machine?
No, the laser - cut products can be welded by laser welding machine.
Q:What are the major differences between the laser beam welding machine and the optical fiber transmission system?
Hard light refers to the direct out of the lens, the structure is bulky, flexible control, fiber transmission, laser and welding robot can be separated, easy to maintain, and can weld complex components.
Q:What are the regulatory requirements for laser welding machines? What materials need to be prepared for export laser welding machine and do we need to do the inspection? The HS encoding is 8515800090.
Have you exported laser welding machines? HS code if 8515800090, regulatory conditions free of inspection, free export permit, export declarations need to provide contracts, export invoices, packaging list, if wood packaging, to provide merchants fumigation certificate. In addition, the clients' information shall be handled according to the contract requirements, such as invoices, checklists, operation manuals, CE certificates, certificates of conformity and so on.
Q:Is fiber transmission laser welder harmful to people?
This is OK, that is, produce an instantaneous high temperature arc, no problem. My classmates often do experiments, they should be fine...
Q:Welded by laser welding machine, separate stainless steel, welded, polished, polished, polished, cleaned, or a little bit of sand holes, how can ah?
Continue to use laser welding repair welding. After the welding is repaired, then the polishing process will be fine. If the hole is large, argon arc welding repair, more fill up. Just do it over again!!
Q:How to adjust the light path of laser welding machine
The same as the cutting machine
Q:Optical fiber marking, parameter setting, laser welding machine, parameter setting!
Fiber laser marking machineParameter:Equipment type: HF-M10, M20, M30, M50Laser power: 10W, 20W, 30W, 50WLaser wavelength: 1064nmBeam quality M2:1.0~1.1Repetition frequency: 2080KHzMaximum line speed: 12000mm/sEngraving: = 300mm*300mm (customizable larger size)Minimum linewidth: 0.006mmMinimum character: 0.1mmPower consumption: 500WCooling mode: air coolingElectricity demand: 220V/50HzWidely used in: mobile phone manufacturing industry, Hui Electronics, automotive industry, medical equipment, watches and clocks, hardware, jewelry, sanitary ware and so on.
Q:When laser welding machine is used to weld stainless steel, what is the general setting parameter?
This is not dead, you go to a little debugging to try to know the parametersThere are some gaps in the material, and different parameters will appear
Q:Can laser welding machine solder products? Such as tin pots and so on?
Laser welding can solder, but you said that the tin pot is a whole? Or by soldering brass or alloy pot. In Shandong there is a customer let us give him proof, but he is a tin kettle pot of the ordinary, his profit is relatively low, with the laser soldering cost is high. But if it is the kind of high-end SUPOR kettle or can do. We have a metal whistle Yiwu customers is also used in soldering. I hope you can provide to you want to understand the data.
