Introduction to laser repair welding of titanium alloy

At present, many metal products use titanium alloy instead, However, during the welding repair period, Still being dependent on the laser equipment, Titanium alloy material is higher than other materials because of its strength and corrosion resistance, Instead of the technology applications in other industries, Especially in the application of high and new technology, For example, the external structure of engines, machine parts and other products, It not only reduces the weight of the product itself, Also improve the machine quality and safety, For a full application, in the process of manufacture, Often requires a variety of facilities, For example, the welding and repair needs to use a laser welding machine to repair the welding, Markers can also use the laser laser machine as the leading equipment, therefore, Titanium alloy material and laser equipment are also interconnected.

Using laser welding machine for titanium alloy welding from large to process products, fixture can be used to add, realize efficient titanium alloy laser repair welding technology introduction can production, in the precision product whatever the degree of complex structure is not limited by the operation of the laser welding machine, for the use of various shapes can be efficient and fast, on quality there are other equipment compared to high performance fast fusion, more than the level of the traditional equipment, so fast and efficient application from repair to welding cycle can be shortened, so also save on cost, more cost-effective matching.

From the characteristics of the laser welding machine and the performance of titanium alloy analysis, for large devices with laser technology can avoid traditional manufacturing technology for equipment and large specifications of raw materials, for complex cavity structure, all can be solved, so the laser technology in titanium alloy material welding from the cost and material are the choice. Titanium alloy material is often used in parts and machinery, so the position of repair and welding is also more, from the defects of process technology and equipment production, to the defects, cracks and size differences of the parts, seriously affecting the model development progress. But based on laser welding technology repair technology arises at the historic moment, relatively conventional repair technology, repair with high performance, good equipment accessibility, small size, short repair cycle, low comprehensive cost, suitable for expensive parts repair of titanium alloy, can maximize the conventional technology irreparable parts (including operating aircraft parts), to solve the high and new technology development and parts use process defects, damage, corrosion provides a new quick solution.

The application of laser repair technology in China has been on a small scale, Ensure the application of the advance engineering and the use of the parts, Verification of laser welding and repair, Compliance verification based on the suitability criteria, Ensure the safe and reliable use of all industries; Laser welding machine adopts the internal mechanism of repair, Including the forming and heat treatment process and organization, performance control, Distribution rule and elimination of internal stress, Inhibition of deformation and cracking and other basic research; Research on the quality evaluation technology of laser welding and repair, 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 equipment for engineering application, Improve the forming stability, Improve the real-time detection methods, Achieve the best match for accuracy (size and shape) and rate.
