Discussed is an electrode lead bending and welding apparatus including a base portion movable in a vertical direction and a horizontal direction, a bending portion attached to the base portion and extending away from the base portion, and a sensing portion attached to the bending portion and rotatable; . A welding between an electrode lead and a busbar of a battery cell is performed in the state in which the electrode lead is bent by the bending portion, . Also discussed is an electrode lead welding method using the electrode lead bending and welding apparatus.

A jig device for laser welding of the disclosure inclides a jig body having a semi-oval shaped seating groove in which a lower side of a refrigerant pipe to which a charging port is coupled is seated: a first pressing block provided in an upper portion of one side of the jig body and having a first groove part configured to press an upper portion of one side of the refrigerant pipe and an upper portion of one side of a fixing part of the charging port at a lower surface thereof; and a second pressing block provided at an upper portion of the other side of the jig body and having a second groove part configured to press an upper portion of the other side of the refrigerant pipe and an upper portion of the other side of the fixing part of the charging port at a lower surface thereof.

A method of repairing a rod guide assembly of a fuel control unit of an aircraft engine is provided. The method comprises disconnecting a used spring seat from the rod of the rod guide assembly and welding a replacement spring seat to the rod using an electron beam controlled using a circular beam deflection pattern.

A boring device includes: a rotatable body, which has a workpiece holder, a valve seat receiver and a debris passage portion; a laser emitter; a pump and a control unit. The workpiece holder can hold a nozzle body. The valve seat receiver contacts a valve seat of the nozzle body that is held by the workpiece holder. The laser emitter emits a laser beam to an outer wall of the nozzle body to bore injection holes at the nozzle body. The debris passage portion includes a debris passage that is placed on a radially inner side of the valve seat receiver and guides debris formed at the time of boring the injection holes with the laser beam. The pump vacuums the debris through the debris passage. The control unit controls a laser output power of the laser emitter and a suction force of the pump.

A welding method and system (4) using a robotic arm (10), a welding robot (18) and a welding table (2) placed at an angle from horizontal to hold two C-channels (6 and 8) facing each other to maintain position and be welded together. C-channels (6 and 8) face each other to form a closed channel at increased welding speed with less materials having resulting benefits including constant welding, less distortion, and less welding material. Welding begins with restraining C-channels (6 and 8) in conjunction with the angled welding table (2). A robotic arm (10) handles C-channels (6 and 8) to move, place and restrain them relative to each other and the welding table (2). A pressing tool (12) may be a set of pressure-exerting tools (26). A welding robot (18) with a seam finding system (24) preferably welds the restrained C-channels (6 and 8) from top to bottom.

One or more clamping aid tools for mounting to various squares and straight edges, including carpenter squares, framing squares, speed squares or the like, and various straight edges and rulers for easily and accurately positioning various objects, either flat and/or round, magnetic or not. The clamping aid tools can secure these squares and straight edges to various objects while they are being fitted, secured and/or welded together.

Workpiece-holding tools and techniques are described. Workpiece-holding tools and techniques are usable to ensure consistent and durable alignment of various workpieces while providing access for performing attachment techniques thereon. In one example, the workpiece-holding tool is configured to allow objects to be held or removably affixed to an alignment surface. Holding objects with the workpiece-holding tool ensures that the alignment of objects with an alignment surface does not change while a user is operating upon a workpiece, e.g., as by joining aligned objects together, without interfering or obstructing access to the objects. The ability to hold objects is enhanced by the inclusion of cutouts that provide increased access to interior surfaces of the workpiece-holding tool, such as to increase the area available for use of clamps or other fastening devices.

A welding clamping device includes a base plate and two positioning slide blocks, each of the positioning slide blocks includes a slide base and a cam, wherein the slide base includes a support plate and two cam holders fixed at two opposite ends of the support plate; the cam is rotatably mounted between the two cam holders via a camshaft for press-fitting a workpiece to be welded; and the base plate is provided with a slide slot, and the two positioning slide blocks are relatively slidably mounted in the slide slot. The device can better position a workpiece to be welded, improving welding quality; and clamping and unloading are easy and take a short time, improving welding efficiency.

A tooling holds a blade during friction welding to a rotor element. The tooling includes a fixed jaw having a central part; two arms separated by a distance d for receiving at least one portion of the blade; and a fixed jaw body with bearing surfaces and a bore for receiving at least one portion of the blade. The bearing surfaces are configured to come into contact with the blade. A movable jaw includes a movable bearing surface that comes into contact with the blade, and pressure means that moves the movable jaw towards the fixed jaw body to press the blade.
