The 8th academy of aerospace science and technology breaks through the laser welding technology of titanium alloy structural parts

Recently, aerospace science and technology corporation, which is eight yuan 800 using laser welding technology developed by the types of complete sets of shell first one-time through the X-ray testing, not only on the size of deformation control to achieve the innovation breakthrough, in the special joint form of laser welding technology on the new cross, solved the lock bottom joint penetration laser welding of stomatal control problem.

It is reported that the whole set of shell is faced with two major problems in laser welding, such as deformation and excessive porosity. Therefore, the research team made a bold exploration on the overall manufacturing scheme and assembly method, which effectively took into account the assembly efficiency and assembly quality, and finally explored a new method that could significantly inhibit the porosity and achieved the desired effect.
