Laser repair welding technology for titanium alloy

At present, many metal products are replaced by titanium alloy, but during welding and repair, they still rely on laser equipment. Titanium alloy material, because of its higher strength and corrosion resistance than other materials, has replaced the technical applications of other industries, especially high-tech applications, such as: Engines, parts and other products for external use, such as the structure not only reduce the weight of the product itself, also improve the quality and safety of the machine, to the application of fully, in the process of production, often need to application the collocation of a variety of facilities, such as welding repair on the need to use laser welding machine repair welding, laser laser machine tag can also be used as the main equipment, therefore, Titanium alloy materials are also interlinked with laser equipment.

With laser welding machine to welding of titanium alloy products, from big to process the fixture can be used to add, can achieve efficient production, products in the precision degree regardless of the extent of the complex structure are not restricted by the operation of the laser welding machine, for all kinds of shapes can be efficient and fast to use, there are also other equipment on quality unmatched by high-performance rapid convergence, Beyond the application level of traditional equipment, such a fast and efficient application from repair to welding cycle can be far shortened, so there is also a great cost savings, more cost-effective matching.

From the characteristics of laser welding machine and the performance of the combined analysis of titanium alloy, for large parts of the repair using laser technology can often avoid the traditional manufacturing technology to strict requirement of the equipment and large size materials, for complex cavity structure, all can be solved, so the laser technology in the welding of the titanium alloy material from the cost and the material is not second choice.

Titanium alloy material is often used in parts and machinery, so the repair and welding position is also more, from the process technology and equipment production defects, to parts defects, cracks and size differences caused by the problem, seriously affected the model development progress. But based on the technology of laser welding repair technology arises at the historic moment, relatively routine repair technology, has the restoration performance is high, good accessibility of equipment, restricted by parts size small, short repair cycle, low comprehensive cost etc, applies to expensive parts such as titanium alloy repair, can maximum limit save conventional techniques cannot repair parts (including operating aircraft parts), To solve the high and new technology development and the process of using the parts defect, damage, corrosion, etc. Provides a new efficient solution, the application of laser repair technology in domestic has small size, to ensure that the use of advanced engineering applications and parts, laser welding and repair the full-size structure static and fatigue test validation, based on suitable for standard conformance verification, Ensure the safe and reliable use of various industries; Deep research on the internal mechanism of laser welding machine repair, 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 documentation system, including manufacturing standards and test standards, etc. Laser welding and repair manufacturing technology research, the development of engineering application of complete sets of equipment, improve the forming stability, improve the real-time detection means, to achieve the accuracy (size and shape) and speed of the best match.
