摘要： An ultrasonic system has an ultrasonic stack excited by a power supply. The ultrasonic stack has a plurality of components, including an ultrasonic converter, a booster and an ultrasonic horn. A method of controlling the ultrasonic system with the power supply includes upon replacing any of the components of the ultrasonic stack with a replacement component, inputting an amplitude parameter of the replacement component into the power supply, determining with the power supply an amplitude of an AC excitation signal at which to excite the ultrasonic converter based on amplitude parameters of the components including the amplitude parameter of each replacement component. The power supply then sets the amplitude of the AC excitation signal at this determined amplitude.

摘要： A loose stack joint and/or cracked ultrasonic stack component of an ultrasonic stack of an ultrasonic device are detected by measuring a test damping coefficient with a test scan of the ultrasonic stack. The test damping coefficient is compared with a previously measured baseline damping coefficient. It is determined that the ultrasonic stack has a loose stack joint and/or a cracked ultrasonic stack component when the damping coefficient is greater than the baseline damping coefficient by more than a predetermined amount.

摘要： Methods of mitigating current overload of an ultrasonic system having an ultrasonic stack under load at startup are provided. The methods include beginning an ultrasonic cycle in the ultrasonic system having the ultrasonic stack that runs a closed loop phase control through the weld cycle by ramping up the power of the ultrasonic stack under load. During ramping up of the power of the ultrasonic stack under load, a controller lowers the phase to a negative phase. After ramping up the power of the ultrasonic stack under load is complete, the controller raises the phase to 0 degrees and the ultrasonic stack is operating at steady state and with the phase at 0 degrees.

摘要： Laser channels of a simultaneous laser welding system are controlled using profiling where there is a profile associated with each laser channel for each active weld step of the laser channel and the laser channels are controlled using the respective profiles for each active weld step of each laser channel. In an aspect, the actuator of the simultaneous laser welding system is controlled using one or more of laser light intensity amplitude profiling, force profiling, distance profiling and laser energy profiling. In an aspect, one or more conditions are used to determine when to transition from a step of a cycle of the simultaneous laser welding system. The conditions can be any of time, accumulation of laser energy, actuator position, and actuator force.

摘要： Unabsorbed infrared laser light that has passed though plastic parts to be welded with a low absorption TTIr process is recirculated back to the low absorption weld interface for reabsorption in the process. A beam of infrared laser light is directed at the plastic parts to be welded, a transmissive first part and an absorptive (or partially absorptive) second part. The infrared laser light impinges the transmissive part and first transits through the transmissive part to be welded to a weld interface at the junction of the two parts. At the weld interface, either the infrared laser light is partially absorbed by an additive infrared absorber, the infrared laser light is partially absorbed by the absorptive part, or both. The portion of the infrared laser light that is not absorbed continues through the absorptive part and exits the far side. This infrared laser light is then redirected back to the weld interface. On the second pass (and any subsequent passes thereafter), more infrared laser light is absorbed in the partially absorbing medium (the additive infrared absorber, the absorptive part, or both). In an aspect, the parts are tubular parts with the transmissive part coaxially surrounding the absorptive part. The infrared laser light is redirected with a cylindrical mirror that coaxially surrounds the tubular parts. In an aspect, the parts include a tubular part and a fitting and the infrared laser is redirected with a spherical mirror that surrounds the parts.
