Application Of Laser Technology in Welding Of Titanium Alloy
At present, many metal products are replaced by titanium alloy, titanium alloy bars and titanium alloy plates are often used in parts, machinery, so the repair and welding position is also more, from the process technology and titanium equipment production defects, to parts defects, cracks and size differences caused by the problem, seriously affect the model development progress. From the characteristics of the laser welding machine and the performance of titanium alloy combined analysis, for the repair of large devices using laser technology can often avoid the harsh requirements of traditional manufacturing technology for equipment and large specifications of raw materials, for complex cavity structure, can be easily solved, so laser technology in the welding of titanium alloy equipment from the cost and materials are the only choice. During welding repair, titanium alloy equipment replaces technical applications in other industries because of its strength and corrosion resistance compared to other materials, especially high-tech applications, such as: The external structure of the engine, machine parts and other products, not only reduces the weight of the product itself, but also improves the quality and safety of the machine, in order to fully apply, in the production process, often need a variety of facilities with the application, such as welding repair need to use laser welding machine repair welding, marking can also use laser laser machine as the leading equipment, so, Titanium alloy material and laser equipment are also interconnected.
The application of laser repair technology in China has been on a small scale to ensure the application of advanced engineering and the use of parts, laser welding and repair of full-size structure static and fatigue assessment verification, compliance verification based on suitable standards, to ensure the safe and reliable use of various industries; The laser welding machine uses repair internal mechanism to deepen the research, including forming and heat treatment process and structure, performance control, internal stress distribution and elimination, deformation and cracking suppression and other basic research; Research on laser welding and repair quality evaluation technology, establish a complete set of technical document system, including manufacturing standards and test standards; Research on laser welding and repair manufacturing technology, develop complete sets of engineering application equipment, improve forming stability, improve real-time detection means, and achieve the best match of accuracy (size and shape) and speed.
The use of laser welding machine to treat titanium alloy welding from large to process products, can be retrofitted with fixtures, to achieve efficient production, in the degree of precision products regardless of the degree of complex structure are not subject to the operation of laser welding machine restrictions, for a variety of specifications and shapes can be used efficiently and quickly, in quality there are also other equipment can not be compared to high-performance fast fusion, Exceeding the application level of traditional equipment, such a fast and efficient application from repair to welding cycle can be far shortened, so the cost is also greatly saved, more cost-effective matching. The repair technology of laser welding technology came into being. Compared with conventional repair technology, it has the characteristics of high repair performance, good accessibility of equipment, small size limitation of parts, short repair cycle and low comprehensive cost. It is suitable for the repair of expensive parts such as titanium alloy, and can save the parts that cannot be repaired by conventional technology to the maximum extent (including parts of operating aircraft). It provides a new and fast way to solve the defects, damage and corrosion in the process of high-tech development and parts use.
