摘要： A method of forming a unitary metal piece includes providing first and second generally planar metallic portions. Each portion has generally parallel first and second sides opposite each other. Each portion has an end edge extending between the first and second sides. The first and second ends are proximate one another. The end edges are resistance welded together to form a weld joint and produce weld flash on at least one of the first and second sides of the portions. The weld flash on at least one of the first and second sides is ground, and a fluid is applied to the weld joint during the grinding of the weld flash.

摘要： A butt-welding device and a method for butt welding workpieces, especially for double-upset resistance-pressure butt-welding of workpieces, particularly wires, strands and profiles, has first and second clamping members for receiving the ends of the workpieces that are to be joined. At least one clamping means can be moved between a starting position and a welding position. At least one deburring tool is provided for deburring the welded workpiece ends. In addition, at least one sensor is provided to determine the geometric dimensions of the workpieces that are to be joined, especially the diameter, the width or the height in the joining plane or substantially parallel thereto, wherein a control unit controls the movement of the clamping members and/or of the deburring tool as a function of the geometric dimension.

摘要： To provide a fitting member, an annular member, a joined member and a method of manufacturing the joined member, which prevent occurrence of a not-joined portion. A fitting member 10 has a fitting protrusion 10p which is protruded outward on an outside face 10s. An annular member 20 contains a space 20h in which the fitting member 10 is to be fitted. An annular member 20 has an annular protrusion 20p on an inside face 20f. When the fitting member 10 is fitted into the space 20h at a predetermined depth, the fitting protrusion 10p and the annular protrusion 20p fill not-joined portions which may be generated assuming that they are not provided. A joined member 30 is produced by fitting the fitting member 10 into the space 20h at the predetermined depth, so that a contact portion between the fitting member 10 and the annular member 20 is joined in solid phase.

摘要： Provided is a joint component manufacturing method for reducing occurrence of burrs upon bonding between a first member having a hole and a second member having a shaft portion and firmly bonding both members. In the method for manufacturing a joint component 100, a hole-side weak press-fit portion 112 is formed at a hole 111 of a flat plate ring-shaped first member 110. Moreover, each of a shaft-side weak press-fit portion 122 and a shaft-side strong press-fit portion 124 is formed at a shaft portion 121 of a cylindrical second member 120. The hole-side weak press-fit portion 112 and the shaft-side weak press-fit portion 122 are defined by a first weak press-fit interference Lw1 formed thinner than a first strong press-fit interference Ls1. The shaft-side strong press-fit portion 124 is defined by a first strong press-fit interference Ls1 as the minimum necessary press-fit interference for electric resistance welding upon electric resistance welding between the hole 111 and the shaft portion 121.

摘要： A wire welding and grinding station (100) comprises a wire welder (112), an AC electrical motor (114) for powering a metal grinder (116), and an AC power supply (110) for supplying electrical power to both the wire welder (112) and the electrical AC motor (114). The station (100) further comprises a soft start module (118) to reduce inrush current demanded by the electrical AC motor (114) while starting. The use of the soft start module (118) allows using a battery (102) as power supply and the use of a battery as power supply has the advantage of practical movability and stable welding currents.

摘要： According to aspects of the present disclosure, a method includes selecting a faying surface of a first metal substrate, placing a reaction material on the faying surface, and attaching, prior to a second metal substrate being adjacent the first metal substrate, the reaction material to the faying surface via ultrasonic welding. The reaction material is configured to form a metallurgical joint between the faying surface and the second metal substrate adjacent the first metal substrate.

摘要： A method for manufacturing an integrated member and an integrated member manufactured by the method which can improve the joining strength and reduce the manufacturing cost. A method for manufacturing an integrated member by welding a first member formed of aluminum alloy material and a second member formed of ferrous-based material characterized in that the first member contains a predetermined amount of silicon and has a thickness larger than that of the second member. The second member can be pressed against the first member along the thickness direction, and by electrically energizing the pressed-in portion during the pressing period, electric resistance welding can be used. The pressing-in amount is set to a value larger than the thickness of the second member and less than that of the first member. The overlapping margin of the first and second members is set to a value of 0.5 mm or more.

摘要： To bond bonding target members stacked on top of each other without generating dust or spatter into an electrically bonded article with improved mechanical strength against strong vibration etc. A first bonding target member or second bonding target member includes a relative displacement amount setting portion for setting the distance by which the bonding target portion of the first member and the bonding target portion of the second member are relatively displaced during bonding, and a current conduction suppressing layer is formed on the relative displacement amount setting portion. The second or first member includes a setting face that is placed opposed to the current conduction suppressing layer of the first or second member. In a state where the first and second members have been positioned, the distance between the current conduction suppressing layer and the setting face is equal to the width H of the bonded portion.
