Low-carbon rimmed steel as sulfur and phosphorus content, not suitable for laser welding. Low-carbon killed steel due to low impurity content, welding results are good. Medium and high carbon steel and ordinary steel can be a good laser welding, but need to preheat and post weld treatment to eliminate stress, to avoid crack formation. Laser welding of stainless steel. Under normal circumstances, the laser welding of stainless steel welded more easily accessible than conventional high-quality connectors. Due to the high welding speed is very small heat affected zone, sensitization does not become an important issue. Compared with carbon steel, stainless steel, low thermal conductivity coefficient is easier to get deep penetration narrow weld. Laser welding between different metals. High cooling rate of laser welding and small heat affected zone, weld metal for the melting of many different structures have different material compatibility has created favorable conditions. The following has been shown that metal can be successfully laser deep penetration welding: stainless steel - mild steel, 416 stainless - 310 stainless steel, ...
... 347 stainless steel ~ HASTALLY nickel alloy, nickel electrode ~ cold forged steel, nickel content of the different double-metal band. The carton of 50mW green laser pointer is of the black color.

Laser welding as a means of welding plastics has become more popular. The sensitivity of this technique is mainly used to connect plastic products, such as circuit boards, plastic parts of electronic sensors, complex shapes of plastic products, and medical plastic seal and clean demanding products. Laser welding the two pieces of plastic parts, the first clamping the parts together, and then nearly infrared laser NIR (wavelength 810-1064nm), transmitted through the first part, then the second part of the absorption, the absorption of near-infrared laser into heat, the two parts of the contact surface melting, the formation of the welding zone. This welding method, can produce more than raw strength of the weld seam. The manual of green laser pointer should be included in the packing list of 100mW green laser pointer .

The working efficiency of green laser pointer will be tested

This kind of green laser pointer has the higher expense. Deep penetration of the laser impact factors include: laser power, laser beam diameter, material absorption rate, welding speed, shielding gas, lens focal length, focus position, laser beam position, weld start and end point of the laser power gradually rise , gradually decreased control. Deep penetration of laser characteristics and advantages. Characteristics: high aspect ratio. Because the molten metal around the cylindrical steam chamber and extends to the formation of the workpiece, the weld becomes deep and narrow. Minimum heat input. Because the source chamber temperature is high, the melting process occurs very fast, very low heat input workpiece, heat distortion and heat affected zone is very small. High compactness. Because it is full of high-temperature steam in the weld pool small Kongyou Li mixing and gas escape, leading to generate non-porous weld penetration. High cooling rate after welding to weld and easy miniaturization. Strong weld. Precise control. Non-contact, air welding process. The technical reform of 200mW green Laser Pointer should be considered at first.

Advantages: As the focused laser beam is much higher than the conventional method of power density, resulting in welding speed, heat-affected zone and deformation are small, you can weld titanium, quartz and other hard to weld materials. Because the beam is easy to transport and control, and does not require frequent replacement torch, nozzle, significantly reducing downtime auxiliary time, so there are load factor and efficiency are high. As the role of purification and high cooling rate, weld strength, high overall performance. As the balance of heat input is low, high precision, can reduce reprocessing costs. In addition, the dynamic transfer of laser welding costs are relatively low, can reduce production costs. Easy to automate and fine positioning of the beam intensity can be effectively controlled. Deep penetration of laser equipment. Deep penetration of laser generally used continuous wave CO2 laser, these lasers can maintain a sufficiently high output power, resulting in "holes" effect, penetration throughout the workpiece cross-section to form a tough welded joints. The volume of torch type green laser pointer is relatively bigger.

The laser itself, it can produce just as a heat source, a good parallel to the beam direction of the device. If it is oriented and effective treatment of the workpiece after the shooting, the input power to a strong compatibility, so that it can better adapt to the automation process. In order to effectively implement welding, laser and other necessary optical, mechanical and control components together to form a large welding system. The system consists of laser, beam delivery components, the workpiece handling and mobile devices, as well as control devices. This system can be only manually by the operator simply moving and fixed parts, including parts can also be automatically loaded, unloaded, fixed, welding, inspection. The system design and implementation of the total requirement is to secure a satisfactory weld quality and high productivity. Laser welding of steel materials. Ordinary carbon steel and alloy steel laser welding. In general, the good effect of laser welding carbon steel, the welding quality depends on the impurity content. The same as other welding processes, sulfur and phosphorus are the welding crack sensitive factors. In order to obtain a satisfactory weld quality, carbon content exceeds 0.25% needs to warm up. When different carbon steel welded with each other, the welding torch can be a little biased towards low-carbon material side, to ensure joint quality. The technology development of green laser pointer has been finished.
