摘要： A system and method for controlling a weld-current in an arc welding apparatus involves programming of a waveform generator (101) to supply a control signal (105) to a weld-current power supply (106), the control signal (105) being derived from a reference waveform consisting of selected segments having fixed or predetermined amplitudes and variable durations. The reference waveform may be dynamically adjusted in response to changes in welding conditions by feeding the output of an arc current and/or voltage detector (115) back to the waveform generator (101) and varying the duration of selected predetermined amplitude segments.

摘要： A tool feed module (10) for a portable lathe machine tool includes a tool block (32) carrying a cutting tool (38) driven by a feed screw (50) incrementally advanced during a cutting procedure by an actuator arm (26) contacting a striker device (20) located on the tool housing. The actuator arm drives the feed screw through an actuator shaft (60) and a one-way drive device (46) permits the actuator arm to pivot in opposite directions while driving the feed screw in increments during pivotal motion in a single direction.

摘要： An arc welding voltage control loop adjusts a pulsation parameter such as pulse width, pulse amplitude, background amplitude between pulses, or frequency, to compensate for deviations in arc voltage. A second, slower feedback loop adjusts a second parameter to cause the pulsation parameter to return to a desired value due to the effect of the adjusted second parameter on the arc voltage. The second parameter may be the torch-to-workpiece distance, adjusted via a proximity control motor (119) so that when the torch-to-work distance begins to change due to misalignment or changes in workpiece contour during torch movement along the weld path, the weld power source voltage control loop adjusts the pulsation parameter keeping the voltage equal to the voltage command. The slower proximity control adjusts the torch-to-workpiece distance until the voltage control loop returns the pulsation parameter to its original value.

摘要： A process for buttwelding metal workpieces (12) having bevelled joint preparations using an automatic GTAW welder (20) using filler wire (32) includes preparing the bevelled workpieces (12) with bevelled joint areas having minimal land thickness at the root extremities; placing the prepared workpiece joint sections together with an open gap between their adjacent root extremities, the gap having a minimum dimension that avoids harmful compression stress between the workpieces due to weld shrinkage and a maximum dimension that avoids filler wire penetration of the gap; fusion welding the open root area of the adjacent workpieces (12) with a root pass weld using an automatic GTAW welder (20) supplied with filler wire (32) and a shield gas including 1 to 10 % hydrogen and the balance inert gas; and then promptly overlaying the root pass weld with at least one additional filler weld pass using an automatic GTAW welder (20) supplied with filler wire (32) and hydrogen-free shield gas.

摘要： A portable tool for use in axially cutting and squaring ends of tubes includes a main tool body (5) within which is rotatably mounted a tool shaft (49) having a cutting tool (44) attached at one end thereof, a tube receiving and clamping unit (14) for retaining an end portion of a tube (165) to be worked upon, a mechanism (18) for shifting the tool shaft (49) relative to the main tool body (5) so that the cutting tool (44) can progressively engage the end portion of the tube (165) and a power drive unit (77, 73, 83) for rotating the tool shaft. The tube receiving and clamping unit (14) is provided with a plurality of circumferentially spaced ports which provides viewing access to a cutting zone, enables adjustments to or changing of the cutting tool and permits chips cut from the tube to be readily removed from within the tool. The shifting mechanism (18) includes a camming arrangement (19, 180, 188, 198, 199) that ensures smooth shifting of the tool shaft (49) and which is designed to minimize the ingress of foreign matter into the tool.

摘要： A clamping device for clamping a mandrel (28) to an elbow or pipe (18) has a plurality of clamping pins (62), each pin having a generally cylindrical shape with a hemispherical end portion (62a) defining a plurality of concentric ridges (64). An axially moveable actuating member (72) bears on a second end (70) of the centering pins such that movement of the member along the longitudinal axis (30) of the mandrel urges each of the centering pins into contact with the pipe surface.
