| 20100051590 | METHOD FOR BUTT JOINT OF ROLLING PIECES - The present invention relates to a method for butt joint of rolling pieces comprising: cutting a head part of a first rolling piece which is in a feeding direction to form a first inclined butt joint edge in a preset sharp angle θ against a working roll generatrix of a working roll, wherein a value of the angle makes the width of the first inclined butt joint edge along a vertical direction of the working roll generatrix greater than the width of a distortion area where the working roll touches the rolling pieces; cutting a tail part of a second rolling piece which is in the feeding direction to form a second butt joint edge parallel to the first inclined butt joint edge; setting the first inclined butt joint edge and the second inclined butt joint edge relatively clingy; and welding relatively clingy parts to connect the first rolling piece with the second rolling piece. The present invention greatly ensures the intensity of the rolling pieces, prevents the rolling piece from being ruptured and ensures the stability of the rolling speed of the whole continuous rolling system and the quality of the rolling pieces. | 03-04-2010 |

The seam welding apparatus includes a load cell mounted on the robot, for detecting a load imposed along a Y direction which is perpendicular to a pressing direction Z along which the electrode rolls press the workpiece at a weld point and a delivering direction X along which the robot delivers the workpiece at the weld point, a robot controller and an arithmetic unit, a turning mechanism for turning the electrode rolls about the pressing direction Z, and a control device for controlling the turning mechanism to operate depending on the magnitude of the load in the Y direction detected by the load cell. | 07-08-2010 |
| 20100219165 | METHOD OF AND DEVICE FOR BUTT WELDING WITHOUT WELD FILLER MATERIALS THIN METAL SHEETS USING CLAMPING PRESSING DEVICES, AT LEAST ONE PRESSING ELEMENT BEING SUITABLE FOR APPLYING TWO OR MORE DISTINCT PRESSURE LEVELS - A device for the linear butt welding of thin metal sheets without weld filler materials comprising movable welding heads, a clamping device having at least two pressing elements which operate independently of one another at least one of the pressing elements being suitable for applying two or more distinct pressure levels and additional horizontal pressing elements are further provided in order to press the metal sheets to be welded against one other while being deformed, until full-area contact of the metal-sheet edges butting against one another is achieved as well as a welding method making use of the device. | 09-02-2010 |
| 20110278264 | GUIDE WIRE - A guide wire includes a first wire disposed on the distal side of the guide wire and a second wire disposed on the proximal side. The second wire has an elastic modulus larger than the first wire. The first wire is joined to the second wire at a welded portion by welding. A coil is disposed on the distal side of the first wire. A cover layer is formed on the outer peripheral surface of the wire member in such a manner as to cover at least the welded portion. The cover layer is made from a material capable of reducing the friction of the cover layer, for example, a fluorocarbon resin or a hydrophilic material, to thereby improve the sliding performance of the guide wire. Such a guide wire is excellent in operationality and kink resistance. | 11-17-2011 |
| 20120248071 | RESISTANCE WELDING METHOD AND RESISTANCE WELDING JIG - In resistance welding, an end portion and a flange portion are welded together at contact surfaces thereof by applying a voltage between two electrodes a while an inner casing and a main metal piece are pressed in directions toward each other. When a shearing stress due to the pressure is applied to a ceramic guide pin, the guide pin is more resistant to wear as compared to a phenolic resin guide pin, for example. In addition, a clearance is provided between a large-diameter portion of the guide pin and an inner surface of a guide-pin insertion hole. Accordingly, the guide pin is capable of tilting in the radial direction, to partially absorb the shearing stress. Therefore, the guide pin is more resistant to breakage compared to a non-tilting ceramic guide pin. Thus, the life of the guide pin used in the resistance welding process can be prolonged. | 10-04-2012 |
| 20140246407 | GUIDE WIRE WITH CORE HAVING WELDED WIRE SEGMENTS - An intravascular guide wire having two core materials joined together without the use of a connector tube or sleeve, the core materials being stainless steel and psuedoelastic metal alloy, nitinol. The core materials are joined to each other through an intermediate transition piece made essentially of nickel, which is welded on either side to the two core materials. In a multi-segment intravascular guide wire, discrete, high modulus and medium modulus core portions of different materials are welded to a shapeable, low modulus distal core portion made of a third material having a flattened, shapeable section at a most distal end that is not welded to but made from the distal core portion, so the flattened, shapeable section can be deformed to create a steerable tip. Processes such as simultaneous resistance and friction welding can be used to join the core portions. | 09-04-2014 |

The individual ones of the at least two clamps are positioned within the wire welder such that the ends of individual ones of the respective wires, when held by the respective clamps, will contact each other. One or more individual ones of the at least two clamps are associated with an adjustment axis about which the individual ones of the at least two clamps are configured to rotate. An adjustment mechanism is operatively coupled to fix one or more of the at least two clamps corresponding to the associated adjustment axis at an angular orientation with respect to a second clamp. | 09-18-2014 |
