A coaxial connector for interconnection with a coaxial cable with a solid outer conductor by ultrasonic welding is provided with a monolithic connector body with a bore. An annular flare seat is angled radially outward from the bore toward a connector end of the connector, the annular flare seat open to the connector end of the connector. An inner conductor cap is provided for interconnection with an inner conductor of the coaxial cable by ultrasonic welding. The ultrasonic welding of each of the inner and outer conductor interconnections may be performed via inner conductor and outer conductor sonotrodes which are coaxial with one another, without requiring the cable and or connector to be removed from their fixture.

The present disclosure can provide for an ultrasonic welding method for a pair of workpieces. The method can include first pressing an ultrasonic welding stack against a first workpiece in the pair so that the first workpiece comes into contact with a second workpiece in the pair. The method can then provide for initiating a weld phase by outputting energy from the ultrasonic welding stack to the first workpiece. The method can provide for monitoring, with at least one sensor, a sensed parameter. The sensed parameter can be, for example, weld force and/or weld force rate of change. The method can provide for determining whether the sensed parameter has reached a predetermined level. Based on determining that the sensed parameter has reached the predetermined level, the method can provide for ending the weld phase.

A linear friction welding system includes a processing circuit configured to execute program instructions stored in a memory to control a first motor using one of a torque and speed control, placing a plurality of timing gears in a configuration wherein a fixed projection of one of the timing gears is at a trail position of a slot of another timing gear such that two power shafts of a cam assembly are rotating in phase and a ram is motionless. The processing circuit further controls a hydraulic press to generate a pressure between two components to be welded with the power shafts rotating in phase, and controls the second motor using the one of the torque and speed control to place the timing gears in a second configuration whereat the fixed projection is at a lead position of the slot thereby forcing the ram to oscillate.

A resin piping assembly including a base divisional component having first and second half components having respective first and second interfacial surfaces formed along an oil passage, and first and second divisional components which have respective third and fourth interfacial surfaces formed along the oil passage, and which are bonded to the respective first and second half components. Each of the base divisional component, and the first and second divisional components is formed of a resin material, and the first and second interfacial surfaces are spaced apart from each other, and open in respective opposite directions. The base divisional component further includes a cylindrical connecting pipe portion having a connecting passage portion which is a part of the oil passage and which is provided for communication between the first and second passage portions. Also disclosed is a process of forming the resin piping assembly.

A vibration welding device includes a base plate, a vibrating body, and a plurality of position adjusting jigs. The vibrating body is capable of vibrating while holding an interior part which is an object to be welded. The base plate is disposed below the vibrating body. The base plate holds an instrument panel which is an object to be welded. The position adjusting jigs are connected to the vibrating body so as to be adjustable in position. The plurality of position adjusting jigs are disposed independently of each other.

A vibration welded article includes an outer member having a substantially V-shaped portion, and an inner member that is vibration welded to the outer member. The outer member includes a substantially plate-shaped base surface portion, and a slope portion formed obliquely relative to the base surface portion. The slope portion has an outer member opening which is opened to attach another component. The inner member includes a first joint surface portion that is vibration welded to the base surface portion, a second joint surface portion that is vibration welded to the slope portion, and at least one protruding portion that protrudes from the second joint surface portion toward the base surface portion.
