Application of laser composite welding technology in shipyard
With the development of modern industry, shipbuilding industry is particularly important. Shipyard is the place where ships or ships are built, repaired and overhauled. In shipbuilding and ship repair work, welding is one of the main processes. Therefore, the development of welding technology and equipment is the investment of shipbuilding technology. In recent years, the laser composite welding technology has been developed rapidly. It has been widely used in the shipbuilding industry for its many advantages.
The principle and characteristics of laser composite welding technology
The laser composite welding technology is the combination of laser welding and arc welding. It uses the arc welding technology as the main body, and the laser+arc welding technology as the assistant, so that the arc welding workpiece can also obtain better performance than the traditional arc welding.
The reason why this technology has such a good effect is that the laser used has high energy density and the speed of welding is very fast. Compared with the traditional arc welding, the welding heat affected zone is very small and the heat input is very low. It can realize the welding without filler material, the welding speed is fast, the deformation is small, and the composite welding is available. In addition, the welding seam is beautiful and tensile strength is high.
Application of laser composite welding technology in shipbuilding industry
Laser composite welding technology has been widely used in the construction and renovation of ships and other steel structures. Compared with traditional welding processes, laser composite welding can save about 30% of the welding cost, improve the welding quality and production efficiency. It can not only weld the large thickness and complex structure, but also the narrow seam width and thin plates.
In shipbuilding and ship repair work, seam welding, butt welding and fillet welding are the main welding methods. In these welding methods, the use of laser composite welding technology can reduce a lot of time and manpower consumption. Especially in the splicing and reinforcing reinforcement of the thin plate, even in the welding of complex structural components, the laser composite welding technology has its unique advantages.
In addition, in the shipyard, welding robot is a valuable part of automation welding. Compared with manual welding and traditional automatic welding, laser welding robot has higher welding accuracy and faster welding speed. This welding robot is controlled by a computer, and its program can be set according to the shape and size of the workpiece. Therefore, it can achieve the automatic welding of large and complex parts, which greatly improve the welding efficiency and reduce the labor intensity of workers.
Conclusion
In summary, the application of laser composite welding technology in shipyard has many advantages. It has high welding speed and weld quality, good efficiency and small deformation. And the use of welding robot has the advantage of automatic welding, especially for large and complex parts. Therefore, this technology is not only beneficial for the shipbuilding industry, but also for other industry.
