Hybrid laser arc welding process and apparatus

Номер: US20120000892A1
Принадлежит: General Electric Co

A welding method and apparatus for welding workpieces together by conducting a laser beam welding process on a joint region that includes a weld seam defined by and between faying surfaces of the workpieces, and then conducting a hybrid laser arc welding process on the joint region. The laser beam welding process entails causing a first laser beam to travel along the joint region, penetrate the weld seam and form a weldment. The hybrid laser arc welding process remelts the weldment by simultaneously causing an electric arc and a second laser beam to overlap and travel along the joint region and form a weld pool in the weldment. On cooling, a weld joint is formed within the joint region and its weld seam.

Tin-silver bonding and method thereof

Номер: US20120199635A1
Принадлежит: National Central University

A Sn—Ag bonding and a method thereof are revealed. By means of a bonding layer formed by tin and silver between wafers, the stress released by diffusion and bonding between tin(Sn) and silver(Ag) is larger than the stress released by diffusion and bonding of conventional gold-silver bonding. Moreover, a Sn—Ag bonding method of the present invention forms Sn—Ag bonding at low temperature and releases more stress so as to reduce thermal stress generated during wafer bonding effectively. And after wafer bonding, the high temperature processes can be performed.

Parts are welded by way of a laser beam, wherein the parts are oriented and fixed relative to each other, a laser beam is introduced into an upper part from above and centered relative to a joint point and fuses only the inner region directly above the joint point, while the upper part and the lower part are pressed against each other and therefore move toward one another, wherein the fused region of the upper part penetrates the material of the particular lower part, which has likewise fused in the meantime. Laser welding makes it possible to weld the parts so as to form products having nearly any type of geometry with much less effort than with resistance welding or capacitor discharge welding.

A laser machining equipment for etching grooves in a wall of a mechanical part, or in a connecting rod for a spark ignition engine, includes a fiber optic laser device arranged to supply laser pulses. The fiber optic laser device is controlled so that laser pulses have a peak power of more than 400 W and at least two times greater than maximum mean power of the laser device, and duration of the laser pulses is below or within the nanosecond range of 1 ns to 1000 ns. The fiber optic laser device can be controlled in a quasi continuous wave (QCW) mode, or can be controlled in a Q-switch mode. The selected operating modes increase machining efficiency and produce a groove with an optimum transverse profile, particularly with a small mean radius of curvature at a bottom of the groove which then allows precise subsequent fracturing of the mechanical part with less force.
