Introduction to titanium alloy laser repair welding technology
Currently, many metal products have been replaced by titanium alloys, but laser equipment is still relied upon for welding and repair. Titanium alloy materials have higher strength and corrosion resistance than other materials, and have replaced technical applications in other industries, especially high-tech technical applications, such as the external structure of engines, machine parts and other products, which not only reduce the product's The weight product itself also improves the quality and safety of the machine. In order to be fully applied, a variety of facilities are often required in the production process. Applications such as welding repair require the use of laser welding machines for repair and welding. Laser machines can also be used as the leading equipment for marking. Therefore, titanium alloy materials and laser equipment are also related to each other.
Laser welding machines are used to weld titanium alloys from large parts to machined products. Clamps can be used for installation to achieve efficient production of titanium alloy laser repair welding technology. In terms of accuracy, no matter how complex the structure of the product is, it will not be affected by laser welding. Due to the operating limitations of the machine, it can be applied to products of various specifications and shapes efficiently and quickly. In terms of quality, it also has high performance and fast integration that other devices cannot match. Beyond the application level of traditional equipment. With such a fast and efficient application, the cycle from repair to welding can be greatly shortened, so the cost is also greatly saved, making it more cost-effective.
From a combined analysis of the characteristics of laser welding machines and the performance of titanium alloys, the use of laser technology to repair large devices can often avoid the strict requirements of traditional manufacturing technology on equipment and large-size raw materials. Complex cavity structures can be easily solved. Therefore, in terms of cost and materials, laser technology is the only choice for welding titanium alloy materials.
Titanium alloy materials are commonly used in parts and machinery, so there are many areas that require repair and welding. Problems ranging from defects in process technology and equipment production to defects, cracks, and size differences in parts have seriously affected the progress of model development. . However, repair technology based on laser welding technology emerged as the times require. Compared with conventional repair technology, it has the characteristics of high repair performance, good equipment accessibility, small part size restrictions, short repair cycle, and low overall cost. Suitable for titanium alloy. The repair of expensive parts such as this can save to the greatest extent parts that cannot be repaired by conventional technology (including parts that operate aircraft), and provides a way to solve problems such as defects, damage, and corrosion that occur during the development of high-tech and the use of parts. new, fast solutions.
The application of laser repair technology in our country has reached a small scale, ensuring the application of advanced engineering and the use of parts, full-scale structural static and fatigue assessment verification of laser welding and repair, and compliance verification based on appropriate standards to ensure safe and reliable use in various industries ; In-depth study of the intrinsic mechanism of laser welding machine repair, including basic research on forming and heat treatment processes and structures, performance control, internal stress distribution and elimination, deformation and crack suppression; Research on laser welding and repair quality evaluation technology, and establish a complete set of Technical document system, including manufacturing standards and testing standards; research laser welding and repair manufacturing technology, develop complete sets of equipment for engineering applications, improve forming stability, improve real-time detection methods, and achieve the best match between accuracy (size and shape) and speed .
