Laser welder is commonly applied to many industries,such as kitchen and bathroom industry, home appliance industry, advertising industry, mold industry, stainless steel product industry and so on. And its processing material includes stainless steel, carbon steel, aluminum sheet and galvanized sheet.
1.Operating principle
It is a new and upgraded laser welding equipment, which belongs to non-contact welding.There's no need to pressure during the process of working.
Its operating principle is that workers make the surface of material directly exposed to high-energy laser beam to achieve internal melting of the material by the mutual reaction of laser and material, then they will cool crystals to form laser joints.
2. Advantages
The laser welder has varieties of advantages and they will be explained in detail. Laser welder could be used in a wide range , it works well no matter in outdoor or from long distance. And the machine can be used flexibly and conveniently in various working occasions. Besides, there are many welding methods offered for users to choose, stitch welding, butt welding, vertical welding, flat fillet weld, inside corner weld and outside corner weld, and it has free switching of welding and cutting, users only need to change a welding nozzle to a cutting nozzle.The welding effect is good because of small heat affected zone, hard to deform and blacken, welding deeply, full melting, compact and firm structure, high weld strength.
There is no need to polish welding joint for it adopts continuous welding, the surface of welded part is smooth and well-done with no perlage and few subsequent polishing procedure. Little consumable material needed in welding process to save the costs of material. This machine is equipped with safety alarms. The nozzle works only when it touches metals and automatically stops outputting laser once the working parts moved from the platform, and the tact switch has the function of temperature sensing.Therefore, this machine has a high safety level. Last but not the least, laser welder is labor-saving for it could be operated by workers who only have short-term training. In a nutshell, the laser-welder is friendly to both owner and user with advantages of time saving, labor saving and cost saving.
3.Structure
The main parts of laser welder are welding head, displayer, control board, wire feeder and water chiller.
(1) Welding head
The laser is eventually fired from the welding head and applied to the material.It consists of nozzle,scale tube, protective glass,focusing lens, reflector,motor,collimator,wire feeding bracket, switch button, waterways,QBH protective sleeve and so on. Nozzle and protective lens are wearing parts. And when workers' welding, auxiliary gas is often needed to avoid material producing gas that could react with air and to avoid residue and aerosol entering the welding head to damage the components.So we need to prepare extra nozzles and protective lens. How laser welding works？The laser is generated by laser source and is transported to welding head, then it is collected and reflected by reflector and is focused by focusing lens to reach the nozzle and finally fired to the material, after all this happens, the user could conduct welding conveniently and flexibly.
(2) Main body
Displayer is a window for interaction between user and machine. The screen of displayer is touch screen, its functions are machine parameter adjustment and language conversion. Control board equals to computer mainframe. And wire feeder is designed to melt the wire into the welding joint during material processing when the welding joint width over 5 mm. Water chiller is used to cool laser source and welding head and could only be filled with distilled water and purified water in summer and with antifreeze in winter. And the volume of liquids contained is 15L, the replacement period of liquids is 2-3 months.
4. Brands
There are three brands of laser source we should be familiar with, they are MAX, RayCus and IPG. They are different in product price, service and quality. In these brands, IPG, a Germany brand, has the best quality and the most expensive price.
5.Three-in-one laser welder
The advanced version of laser welder is the three-in-one laser welder, as its name suggests, it has multifunctions of of welding, cleaning and cutting. Its welding function is the same as that of a normal laser welder. And it could be easily to changed into the cutting pattern by the change of nozzle, when it is converted into the pattern of cutting, it could only cut some extra and useless pieces of the material edges with less precision and worse effect than normal fiber laser cutters. If it is applied in cleaning, cleaning head and special focusing lens for laser cleaner should be installed. It is easy and convenient in operation and alteration of patterns.
6.Precautions
There are matters need attention when workers operating laser welder. Firstly, keep the welding head's angle at 45 to to create a better welding effect. Secondly, when welding,make sure no one is standing in front of the laser head to avoid laser doing harm to other people. Safety is an eternal issue.
