The development of mathematical models for deep penetration laser welding in recent years is introduced.
For certain applications, the laser welding can even offers a replacement for the sewing process.
Results Compared with silk suture, laser welding had the advantages of fast healing and less inflammatory reaction.
The application results show that laser welding can meet higher strength stress demands for those fatigue load parts, such as intake and exhaust valves, timing gear, suspension equipment.
The over- limit and visual cracks occurred in an aero -engine high pressure turbine blade tip were repaired using laser welding.
The blade tip crack of the high pressure turbine is repaired by using the laser welding, which can reduce effectively the repair cost and increase the economic effectiveness of the engine repair.
