    摘要： An apparatus and method for ultrasonically welding workpieces that reduces sonotrode adhesion during the ultrasonic welding process. The sonotrode includes a contact surface wherein a fluid is deposited on the contact surface prior to the welding process. The fluid may be applied in different ways, including providing an aperture in the contact surface of the sonotrode. In addition, the sonotrode may be cooled below the dew point of the surrounding atmosphere thus causing moisture to form on the contact surface of the sonotrode. Cooling the sonotrode to a temperature above the dew point also reduces sonotrode adhesion during the ultrasonic welding process.

    摘要： An ultrasonic welding apparatus and method for detaching or effecting release of an ultrasonic welding tool stuck or attached to a weldment. The method includes the step of utilizing a mechanism mounted adjacent to the ultrasonic welding tool to hold the weldment in position during welding and/or while the ultrasonic welding tool is withdrawn and, if necessary, using the mechanism to detach the weldment from the ultrasonic welding tool. The method contemplates providing a twist, rotary or axial motion to one of the ultrasonic welding tool or weldment to effect release of the ultrasonic welding tool. The apparatus may include a clamp member having a distinct clamping area or pad located adjacent to the sonotrode or anvil of the ultrasonic welding tool. The clamp mechanism provides vibration control, noise mitigation, and a more uniform boundary condition during welding and facilitates part release upon the completion of the welding process.

    摘要翻译： 一种超声焊接装置和方法，用于分离或实现粘附或附着在焊件上的超声波焊接工具的释放。 该方法包括利用安装在超声波焊接工具附近的机构的步骤，以便在焊接期间和/或超声波焊接工具被拉出时保持焊件的位置，并且如果需要，使用该机构将焊件从超声波焊接中分离 工具。 该方法考虑向超声焊接工具或焊件之一提供扭转，旋转或轴向运动，以实现超声波焊接工具的释放。 该装置可以包括具有与超声焊接工具的超声焊点或砧座相邻的不同夹紧区域或垫的夹紧构件。 夹紧机构在焊接过程中提供振动控制，噪声减轻和更均匀的边界条件，并且在焊接过程完成时便于部件释放。

    摘要： A method of fabricating a foamed metal structure using a powder supply of metal particles, comprising: (a) introducing the powder supply along with foaming agent particles into a propellant gas to form a gas/particle mixture stream; (b) projecting the mixture stream at a critical velocity of at least sonic velocity onto a metallic substrate to create a deposit of pressure-welded metal particles containing the admixed foaming agent; and (c) subjecting at least the coating of the substrate to a thermal excursion effective to activate expansion of the foaming agent while softening the metal particles for plastic deformation under the influence of the expanding gases.
