At present, the laser marking machine can mark on every material in the automotive industry, and can obtain high-quality marking codes and many other contents, so as to be able to trace where each part is used. The marked pattern has a bar code, QR Code or data matrix.
And the laser welding is usually used in key positions of body welding and parts with special requirements for the process. For example, it is used for welding the roof and side panels to solve the problems of welding strength, efficiency, appearance and sealing. ; Used for rear cover welding to solve the problem of right-angle overlap; used for laser tailored welding of door assemblies can effectively improve welding quality and efficiency. Different laser welding methods are often used for welding of different body parts.
Laser Marking Machine for Automobile
The importance of laser in the automotive industry is becoming more and more prominent, and it is increasingly affecting our daily lives.
Clear and consistent marks have to be guaranteed for the automotive Industry with consistent traceability for security purposes. Laser marking systems are the ideal tool for marking legible alphanumeric, bar codes and data-matrix codes on nearly all materials used in automotive manufacturing.
Traditional marking methods for auto parts include: mold casting, electric corrosion, self-adhesive, screen printing, pneumatic marking, etc. Since its inception, laser marking technology has developed rapidly with its clear, beautiful and indelible markings.
Many automotive parts and components are made of materials such as: steel, light metals, and plastics and are marked for traceability and quality control. These markings durable and last the lifetime of the car or the component part, even if they are in contact with high heat and fluids such as oil and gas.
The advantages of laser marking for auto parts are: fast, programmable, non-contact, and long-lasting.
The integrated vision system ensures precise positioning, accurate identification and high economic efficiency. Through these we can trace the manufacturer, and the time and place of component production. This makes it easier to manage any component failure, thus reducing the risk of errors.
Laser marking is widely used in automobile manufacturing. For example, automobile parts, engines, label paper (flexible labels), laser bar codes, two-dimensional codes, etc. are often used for auto parts traceability. And the QR code has the advantages of large information capacity and strong fault tolerance.
It is visible that the laser marking machine can provide the most professional solutions in the laser marking area of the whole automotive industry, from the car body, car frame, hub and tire, various hardware components, central control of the seat, steering wheel and instrument panel, glass and so on.
In view of the above description, our recommended laser marking machine as follows:
Laser welding Machine for Automobile
Laser welding is a welding technique used to join multiple pieces of metal through the use of a laser beam. The laser welding system provides a concentrated heat source, allowing for narrow, deep welds and high welding rates. This process is used frequently in high volume welding applications, such as in the Automotive Industry.
Laser welding speeds up the process of replacing forged parts with stamped parts. Laser welding is used to replace discrete spot welds with continuous laser welds, which can reduce the overlap width and some strengthening parts, and can compress the volume of the body structure itself. As a result, the weight of the vehicle body can be reduced by 56kg. The application of laser welding has achieved weight reduction and emission reduction, which meets the requirements of environmental protection in today's era.
Laser welding is applied to tailor welding of unequal thickness plates, and the benefits are more significant. This technology transforms the traditional manufacturing process-first stamping into parts, and then spot welding into a whole-into: first welding several parts with different thicknesses into a whole, and then stamping and forming, reducing the number of parts and using more materials. Reasonable, the structure and function are significantly improved.
Different laser welding methods are often used for welding of different body parts. The following is a list of several laser welding methods commonly used in the automotive industry.
(1) Laser brazing
Laser brazing is mostly used for the connection of the top cover and the side wall, trunk lid, etc. Volkswagen, Audi, Peugeot, Ford, Fiat, Cadillac, etc. all use this welding method.
(2) Laser self-fusion welding
Laser self-fusion welding belongs to deep penetration welding, which is mainly used for roof and side panels, car doors, etc. At present, many brand cars of Volkswagen, Ford, GM, Volvo and other manufacturers use laser self-fusion welding.
(3) Laser remote welding
Laser remote welding uses robot + galvanometer, remote beam positioning + welding, and its advantage lies in greatly shortening the positioning time and higher efficiency compared with traditional laser processing.
Laser welding can also be applied to cigar lighter ,valve lifters, cylinder gaskets, fuel injectors, spark plugs, gears, side shafts, drive shafts, radiators, clutches, engine exhaust pipes, supercharger axles, and airbag liner repair and splicing of damaged auto parts.
Laser welding has numerous advantages and benefits over traditional welding methods and can greatly reduce costs while improving production efficiency and quality.
Laser welding has the following characteristics:
①Narrow heating range (concentrated).
②The action area and position are precisely controllable.
③The heat-affected zone is small.
④The welding deformation is small, and no post-welding correction is required.
⑤ Non-contact processing, no need to pressurize the workpiece and surface treatment.
⑥It can realize the welding of dissimilar materials.
⑦The welding speed is fast.
⑧No thermal influence, no noise and no pollution to the outside world.
The recommended machines suitable for welding auto are as follows:
