Laser welding is a highly efficient precision welding method that uses a high energy density laser beam as a heat source. Laser welding is one of the important aspects of the application of laser material processing technology. In the 1970s, it was mainly used for welding thin-walled materials and low-speed welding. The welding process is heat-conducting type, that is, laser radiation heats the surface of the workpiece, and the surface heat is diffused to the inside through heat conduction, by controlling the width, energy, peak power and repetition frequency of the laser pulse. The parameters are such that the workpiece melts to form a specific molten pool. Due to its unique advantages, it has been successfully applied to the precision welding of small and small parts.

Laser welding technology is becoming more and more popular in life and industry. It can even be said that welding technology is indispensable in many lines. Just like stainless steel or iron and other hardware, you need welding technology to make it a finished product. Therefore, the process of this welding technology is also getting higher and higher, so what is the welding process requirement?
The welding process is mainly determined according to the material, grade, chemical composition, weldment structure type, and welding performance requirements of the workpiece to be welded. First of all, we must determine the welding methods, such as hand arc welding, submerged arc welding, tungsten argon arc welding, gas metal arc welding, etc. There are many types of welding methods, which can only be selected according to specific conditions. After the welding method is determined, the welding process parameters are determined, and the types of welding process parameters are different. For example, hand arc welding mainly includes welding rod type (or brand), diameter, current, voltage, welding power source type, polarity connection, welding Number of layers, number of tracks, inspection methods, etc.
The welding procedure qualification shall be based on reliable steel welding performance and shall be completed prior to engineering welding. The welding parameters used in the welding procedure qualification are determined in principle based on the weldability test results of the steel to be welded, in particular, the heat input, preheating temperature and post-heating temperature. For the mature steel grades that have been well understood and have clear guiding welding process parameters and have been used for domestic and foreign production in the medium and long term, it is generally not necessary for the construction company to conduct the weldability test.
Laser Welding Machine is a powerful tool for industrial laser welding because of its high welding speed, high processing efficiency, narrow weld heat-affected zone and good weld quality.
High weld quality
The penetration ratio is large, the deformation is small, the solder joints are non-polluting, the welding is non-porous, the appearance is flat and beautiful, and there is no need or simple post-processing.
Good solderability repeatability
Laser output power is stable, Laser Welding Equimpent is stable and reliable, and has high processing consistency
With the flange forming equipment, the whole coil steel plate can be automatically welded into a steel pipe on a high-speed production line.
Advanced detection system
The welding quality can be detected online, and the welding defects that may occur during the welding process are issued in time for timely re-welding to avoid the occurrence of the broken belt.
