Three dimensional laser welding technology is an important application in manufacturing industry. At present, the laser welding machine on the market is suitable for the processing of three-dimensional and thin-walled workpieces. Its welding process belongs to the heat conduction type, and the heat on the surface is guided to the internal diffusion through heat transfer, so as to complete the welding process. Because of its unique advantages, three-dimensional laser welding machine is widely used in the welding processing of medium and thin workpieces.
Application of 3D laser welding machine in industrial manufacturing and processing:
1. Application in automobile manufacturing
Three dimensional laser welding machines are needed for the assembly of stamping parts in white cars, including roof panels, trunk panels and frames. In addition, three-dimensional laser welding machines are also needed for car body structural parts, including doors, body side frame and columns. The car body is generally welded with workpieces of different thickness, which can not only reduce the weight of the car, improve production efficiency and enhance the moldability of workpieces, but also deepen the firmness of the car body.
2. Application of shipbuilding and ocean engineering
We all know that large ships are not only bulky, but also consume a lot of man hours. In the past, ships first made general structural components, and then assembled them one by one on the slipway in the water. At this time, it is very suitable to use laser welding technology to process local components in the sea. They combine the principle of laser welding with mechanical automatic processing technology, which greatly improves the production efficiency, shortens the delivery time, and makes contributions to the shipbuilding industry.
When using three-dimensional laser welding machine to process ships, it can not be in direct contact with the surface of the processed parts. Compared with other welding processes, three-dimensional laser welding technology has small joints, small heat affected zone and smooth and flat welding effect. It is a good helper for ship processing. The size of welding joint determines the cost and quality of welding. Using laser welding joint can realize other welding structure design, which is also the reason why it is widely used in ship manufacturing industry.
Three dimensional laser welding technology can also be used in the processing of other thin-walled parts, such as bellows, oil pipelines, automobile bends and special-shaped closures. The processing methods of these parts depend on the performance of the products and the needs of customers. At present, the processing methods include argon arc welding, plasma arc welding, low current tungsten electrode welding and three-dimensional laser welding. Later, with the extensive application of titanium alloy materials, some processes will cause welding changes, damage to raw materials and increasing production costs due to the nature of thickness in the processing process. When processing thin-walled parts with three-dimensional laser welding machine, the excess heat can be blown out by blowing, so as to protect the complete surface of the workpiece on the premise of completing the welding process, which will reduce the waste of raw materials.
