Method and device for connecting metal pipe based on laser shock wave technology
InactiveCN102225493APrecise and controllable parametersPrecisely controlled peak pressureLaser beam welding apparatusPhysicsPulse beam
The invention discloses a method and device for connecting a metal pipe based on a laser shock wave technology and belongs to the technical field of laser processing. In the invention, a black paint applied to the upper end part of a plugging rod serves as a laser energy absorption layer, and water serves as a restraint layer; a laser pulse beam subjected to parameter optimization enters the interior of a pipe fitting along the axis of the pipe fitting, so as to be irradiated on the absorption layer at the upper end part of the plugging rod through a light guide system; the absorption layer absorbs the energy of the laser so as to be gasified and ionized, thus forming high-voltage plasmas; and the high-voltage plasmas quickly dilate to form a high-amplitude shock wave, thereby promoting the quick dilatational strain of an inner pipe and causing the inner pipe to violently collide with an outer pipe, therefore the parts, which are impacted by the laser shock wave, of the two pipe fittings are plastically deformed obviously; and intensive thermal effect is produced during the collision process so that the interfaces of the collision parts of the two pipes are adhesively jointed together. The method and device provided by the invention are wide in application range, and capable of connecting metal pipe fittings different from each other in melting point, in coefficient of thermal dilation, in thermal treatment condition and in state.

An improved system for handling delicate linear media and in particular to a method and apparatus for winding delicate linear media such as superconducting wire or tape or optical fibers onto a spool. A combination of direct closed loop control and media routing design facilitates the handling of the delicate media without causing damage. The axial tension in the linear media may be closely controlled during winding by means of feedback control loop using tension measurements to control the rotation speeds of the wind-from and wind-to spools. Further, during winding, the delicate linear media is only exposed to large radius bends with no reverse bending. Finally, output devices and features, commercial or otherwise, made possible by delicate linear media handling are revealed. This includes advanced SC devices and features.
