1. The difference between laser cutting machine and flame plasma cutting machine
Cutting technology has important applications in the processing of precision machinery and equipment. Good cutting technology can improve cutting efficiency and cutting quality. Both laser cutting and flame cutting belong to thermal cutting. What are the differences between them?
1. Laser cutting
Laser cutting is using a high power density laser beam to irradiate the material to be cut, so that the material is quickly heated to the vaporization temperature and evaporated to form holes. Cut the seam to complete the cutting of the material. Since there is no tooling cost, laser cutting equipment is also suitable for producing small batches of parts of various sizes that were previously inaccessible. Laser cutting equipment usually adopts computerized numerical control technology (CNC) device. With this device, cutting data can be received from a computer-aided design (CAD) workstation using a telephone line.
2. Flame cutting
Flame cutting is a common way of roughing steel plates. It cuts metal thicknesses from 1mm to 1.2m, but when the vast majority of mild steel plates you need to cut are below 20mm thick, other cutting methods should be used. Flame cutting is to use the high temperature generated during the combustion of iron oxide to cut carbon steel. The design of the flame cutting torch provides sufficient oxygen for burning iron oxide to ensure good cutting results.
Flame cutting equipment is low cost and the only cost-effective means of cutting thick sheet metal, but it has its shortcomings when it comes to thin sheet cutting. Compared with laser, the heat affected zone of flame cutting is much larger, and the thermal deformation is relatively large. In order to cut accurately and effectively, the operator needs to have superb skills to avoid the thermal deformation of the metal plate in time during the cutting process.

3. Repairing fiber laser cutting machine faults
There are many ways to fail in the fiber laser cutting machine, but if we find that the fiber laser cutting machine has failed, we should use a reasonable method to repair the fiber laser cutting machine in time. However, the cause of the fault phenomenon of the fiber laser cutting machine is different, so the solution we need to take is different.
Below, the small series will introduce you to the method of repairing the fault phenomenon of the fiber laser cutting machine:
First, the machine does not work: Check if the fiber laser cutting machine power cord switch is turned on; check if the power cord is connected to the power plug, whether it is loose; check if the panel power is turned on.
Second, the pump does not work properly: Check if the fiber laser cutting machine loop system is blocked; check the liquid level of the entire system to ensure that the pump can receive the liquid and check if the pump motor can be operated.
Third, there is no cooling or refrigeration: check whether the voltage is too low or too high; check whether excessive heat is transferred to the fiber laser cutting machine cooling liquid, resulting in a cooling capacity of the refrigeration system.
Fourth, the pump suction is insufficient: check whether the fiber laser cutting machine is limited; whether the voltage is too low or the fluid viscosity is too high.
When we maintain the fiber laser cutting machine, it is necessary to use the correct way. If the maintenance method is incorrect, it will laser the fiber laser and damage. Everyone finds that the fiber laser cutting machine cannot be resolved, it can contact the manufacturer to solve the manufacturer.

5. How to Adjust the Parameters of Laser Welding Machine
Laser welding is a necessary and first welding processing method in modern industrial production. It is a leap-forward technological advancement to traditional welding and is in line with all application welding in the industrial production field, including high-end fields such as automobiles, shipbuilding, and aerospace. The scope of application is improper. Broad, the following introduces the adjustment methods of the three major parameters of the 2kw laser welding machine.
Laser pulse width:
Pulse width is one of the important parameters in pulsed laser welding, which is not only different from material removal and material melting, but also a key parameter to determine the cost and volume of processing equipment.
Laser power density:
Power density is one of the key parameters in laser processing. With high power density, the surface layer can be heated to the boiling point in the microsecond time range, resulting in a large amount of vaporization. Therefore, high power density is beneficial for material removal processes such as drilling, cutting and engraving. For low power density, it takes several milliseconds for the surface temperature to reach the boiling point. Before the surface vaporization, the bottom reaches the melting point, which is easy to form a good melt welding. Therefore, in conducting laser welding, the power density is in the range of 104~106W/cm².
Laser pulse waveform:
Laser pulse waveform is an important problem in laser welding, especially for thin section welding. When the high intensity laser beam is directed to the surface of the material, the metal surface will have 60~98% of the laser energy reflection and loss, and the reflectivity varies with the surface temperature. During the course of a laser pulse, the reflectivity of metals varies greatly.
Compared with traditional welding, 2kw fiber laser welder has the following advantages:
1. fast speed, large depth, small deformation;
2. Can weld refractory materials, and can weld heterogeneous materials with good results;
3. After the laser is focused, the power density is high. When welding high-power devices, the aspect ratio can reach 5:1;
4. The laser beam is easy to realize the beam splitting according to time and space, and can process multi-beam simultaneously and multi-station, which provides conditions for more precise welding;
5. Micro welding is possible. After the laser beam is focused, a small spot can be obtained, and it can be precisely positioned, which can be used in the assembly welding of micro and small workpieces in mass automated production;
6. It can weld hard-to-access parts and perform non-contact remote welding, which has great flexibility;
7. It can weld at room temperature or under special conditions, and the welding equipment is simple. For example, when a laser passes through an electromagnetic field, the beam does not deviate; The laser can weld in vacuum, air and certain gas environments, and can weld through glass or materials transparent to the beam;
At present, metal welding has higher and higher requirements for welding strength and appearance correction. The traditional welding method will inevitably cause the distortion of workpiece due to its great heat input. In order to compensate for the deformation problem, a great deal of follow-up is required, resulting in higher costs. The automatic laser welding method, the heat input and heat affected area is small, significantly improve the quality of welding parts, reduce the follow-up work cost, greatly improve the welding efficiency and stability.
