Laser welding technology is a high-precision, high-efficiency and reliable structural connection technology. The unique advantages of laser welding machines have been well received by the processing industry. At present, the most advanced technology in the processing field includes welding technology. However, laser welding is used in the actual operation process. There will still be many problems in the production process. How to find and solve the problems is a very important link in the production process of every enterprise.
The standard of welding is based on the quality of the welded product. If the welding is not good, there may be problems with the material. It is necessary to check the quality of the material. If the welding process has not changed without changing the material and material, the continuous part is welded. If it is still very poor, then it means that there is a problem with the workbench and fixture of the laser welding machine.
In the process of welding, pressure test is often used to keep the pressure unchanged, to check the operation of the welding head, and the current detection must be strengthened. In the process of welding, we must consider the thickness of the welding, the thickness of the coating, Changes in metal parts. During laser welding, the quality of laser welding is analyzed and evaluated by monitoring the photoelectric signals such as plasma, the state of molten pool and small holes, and the internal stress concentration and pores of the weld after welding are analyzed by non-destructive testing methods. Technology Online detection of weld surface defects There are three detection principles for detecting welding quality.
Laser can be used for welding many materials, carbon steel, low-alloy high-strength steel, stainless steel, titanium alloy can be welded, and the welding speed is proportional to the laser power. Ships, pressure vessel manufacturing, civil and medical fields.
The production of laser welding technology directly affects parameters including laser pulse energy, laser beam spot diameter, laser pulse frequency, welding speed, shielding gas, etc.
