摘要： PURPOSE:To provide the friction welding equipment capable of performing welding with pressure with high accuracy in a short time. CONSTITUTION:A pallet 45 having a rotatable clamping base 44 on which the central conductor 3 is fixed is stopped on the cutting position, the joining face of the central conductor 3 is cut by a cutting device 48, then, stopped on the pressure welding position, the joining face of a contact part 3c is first cut by the cutting device 48, then, the pressure welding force is applied between the contact part 3c fixed on a holding part 42 and the central conductor 3 by a hydraulic cylinder device 46. Consequently, pressure welding work is immediately performed without producing an oxide film on the joining face.

摘要： PURPOSE:To prevent deformation of a member by the check pressure by fitting a rotation side member to hold the member outer periphery by a check claw, carrying out alignment and fixing the opposite surface of the member press- contact surface by a pin on a check face plate of a rotary head. CONSTITUTION:A pin hole of the member A is fitted on a pin 6 of setting material 5 to set it. The member A is held by the check claw 4 provided on the check face plate 2 on the tip of a rotation axis 1. The check claw 4 is fitted on a guide 3 of the check surface 2, the member A is held and centering is completed at the same time. Since the rotational force of a rotating check face plate 21 is transmitted to the member A via the pin 6, a slip is not generated between the check claw 4 and the member A and a flaw on the surface of the member A can be prevented. Since this is not a cap stopper type, the setup time can be reduced and productive efficiency is satisfactory.

摘要： PURPOSE:To detect the abnormality of a laser beam welding with an AE sensor and to enable the optimum control in the laser beam welding. CONSTITUTION:Sound generated at the time of executing the laser beam welding, is detected with an AE sensor 6 and the AE signal is compared with a reference data 10a. Then, in the case the actual AE signal is more than or less than the reference signal, this AE signal is compared with AE signal patterns 10b in various kinds of non-suitable welding conditions through a CPU 9. This AE signal pattern is the one stored by beforehand examining this pattern at the time of welding generated in the case of being the various kinds of the welding conditions, such as laser beam output, focus positioning of the laser beam, shield gas flow rate, assist gas flow rate, to out of the permissible range. In the case, the AE signal is similar with either one in the AE signal patterns, the welding condition corresponding to this pattern is corrected.

摘要： PURPOSE:To obtain a welding head with good workability by lowering a guide member, fitting a fitting part into a prepared hole of a work and raising it to supply a projection nut when aligning is carried out. CONSTITUTION:The fitting part 44 of the guide member 40 is inserted and fitted into the prepared hole W1 of the work W by lowering of an electrode 26. After the projection nut N is positioned, the upper side electrode 26 is raised by operation of an actuator and then, the projection nut N is supplied. Since there is the positional deviation of the prepared hole W1, when the electrode 26 is again lowered, the tapered surface of the fitting part 44 of the guide member 40 is brought into contact with the open groove edge of torsion of the nut N which is moved to the arrow side by a component force by its cone angle and a guide projection of the nut N is coincident with the center of the prepared hole W1 to complete insertion.

摘要： PURPOSE:To simultaneously measure the current density and energy density of an ion beam, by embedding an ion beam current detector and an ion beam energy detector in a bolt to secure the detectors and electrically insulate them from each other. CONSTITUTION:An ion beam is introduced into a cup 101 and collides against the bottom of the cup so that most of ions are injected into the cup and the other of them are reflected by the bottom of the cup, collide against the wall of the cup and are injected into the cup. The injected ions reach an electric input terminal 80, in the form of an ion current, through an electroconductive cylindrical sheath 701 embedded in an electroconductive bolt 102 screwed into the cup 101. The ions then flow into a measuring instrument 90 in the air. The ion current is measured by the instrument 90 to determine the current density and energy density of the ion beam in terms of the cross-sectional area of the ion beam introduced into the cup 101.
