　　The continuous development of shipbuilding technology has brought about great changes in shipbuilding materials and ship design. The application of laser technology in shipbuilding is unique, which is closely related to the processing and application characteristics of ships and the characteristics of laser manufacturing system. So, what are the specific applications of laser in ships? 　　 In recent years, "precision shipbuilding" and "rapid shipbuilding" have become the main trends of the development of shipbuilding industry. Laser cutting technology has developed rapidly, accounting for more than 70% of the laser processing industry. Shipbuilding industry is mainly based on steel plate raw materials, the use of laser cutting plate, can replace some need to use complex large-scale die punching processing methods, greatly shorten the production cycle and reduce costs. After the laser cutting machine is used to cut off the assembly margin, the phenomenon of on...

　　The top laser welding machine in the use of the process will more or less appear some faults, in order to make the laser welding machine work better, reduce the number of failures, increase the efficiency of work, we must understand the operation of the process should pay attention to the problems and troubleshooting methods. Below, the Otlaser laser marking machine supplier will analyze some common fault treatment methods of the top laser welding machine for you. 　　 1. When the laser welding is wrong, press the emergency stop button in time, the system will automatically cut off the laser control, the servo motor power supply, to prevent accidents, the emergency stop must be initialized after the spring operation; 　　 　　2 of roof, the laser welding machine welding equipment runtime exception to stop: check the touch screen alarm screen related alarm, there is alarm device will automatically switch to the suspended state and reset button will be shining with the frequency of 0...

The working mechanism of 3d laser cutting 　　 Laser cutting is the use of high power density laser beam scanning over the material surface, in a very short period of time to heat the material to thousands to tens of thousands of degrees Celsius, so that the material melting or gasification, and then high pressure gas will melt or gasification material blown away from the slit, to achieve the purpose of cutting materials. 　　The working mechanism of 3d laser cutting is relatively different from that of 2d laser cutting. 3d laser cutting requires constant adjustment of laser cutting head position to ensure that the laser cutting head is always perpendicular to the workpiece surface, so as to obtain excellent cutting quality. In actual production, 3d laser cutting program compilation requires the 3d modeling of parts, and then the introduction of 3d programming system generation path, and manual adjustment according to the characteristics of parts, tooling features, to avoid cutting head...

　　Laser processing advantages and substitution trend is obvious, emerging application demand support performance high growth. 　　 　　New three board laser enterprise overall net profit rose more than 40%, nearly three years on the new three board into the enterprise in the field of laser after finishing, we found that the new three board laser business income and net profit of enterprise overall maintained a high-speed growth, net profit since 2014 are more than 40% of the growth, even in 2015 reached 91%, far more than the new three board machinery sector overall growth. The two core driving forces of laser processing equipment in the future are the substitution of traditional technology and the demand pull of emerging applications downstream. 　　 In 2015, the sales volume of laser cutting equipment was about 6.6 billion yuan. The sales growth mainly came from the fields of OLED panel cutting, 3D glass cutting and sapphire cutting. The sales volume of laser welding equipment is a...

　　Fiber laser is gradually replacing the traditional laser in laser marking, laser welding, laser cutting and other fields of leadership positions. Otlaser explains the advantages of fiber laser marking in various fields. 　　 Application of fiber laser in communication 　　 　　Compared with other types of lasers, optical fiber lasers have obvious advantages in compact layout, heat dissipation, beam quality, volume and compatibility with existing systems, and are widely used in the field of communication. 　　 　　Mode-locked fiber laser with rare earth fiber as gain medium can produce very short optical pulse with high repetition rate, pulse width picosecond or femtosecond, and the laser wavelength falls on the optimal window of optical communication 1.55 microns, which is the ideal light source for high-speed optical communication system in the future. At present, mode-locked fiber lasers with 10GHz and 40ghz repetition frequencies have been successfully developed. Once this communi...

　　The principle of laser cutting machine 　　 　　 Laser cutting is to make the irradiated material melt, vaporize, ablate or reach the ignition point by irradiating the workpiece with the focused high power density laser beam, and at the same time remove the molten material by means of the high-speed airstream coaxial with the light beam, so as to realize the cutting of the workpiece. Laser cutting is one of the thermal cutting methods. The principle of laser cutting is shown below. 　　 Types of laser cutting 　　 　　Laser vaporization cutting is mainly used for cutting extremely thin metal materials and non-metal materials (such as paper, cloth, wood, plastics and rubber, etc.). 　　 　　1. Fusion cutting 　　 　　During laser fusion and cutting, metal materials are melted by means of laser heating, and non-oxidizing gases (Ar, He, N, etc.) are sprayed by the nozzle. Liquid metal is discharged by the strong pressure of the gas to form an incision. It only takes a tenth of the energy to...

　　The cause that uneven marking effect of fiber laser marking machine 　　 　　1. Thermal lens phenomenon 　　 　　When the laser passes through the optical lens (refraction, reflection), it will cause the lens to heat slightly and deform. This deformation causes the laser focus to rise and the focal length to be shorter. If the machine is fixed and the distance is adjusted to the focal point, the laser energy density on the material will change after a period of time due to thermal lens, resulting in uneven marking effect. 　　 2. Reasons for materials, such as inconsistency of film thickness on the surface of materials or changes in physical and chemical properties 　　 　　The material is sensitive to laser energy response. Usually under the same material, the laser energy reaches the material damage threshold. When the coating thickness of the material is different, or some other physical and chemical treatment process is not uniform, the effect of fiber laser marking machine will als...
