Disclosed is a lead welding apparatus, which is used for welding electrode leads of battery cells facing each other, among battery cells of a battery module, and the lead welding apparatus includes a welding unit configured to weld two electrode leads of the facing battery cells to each other, and a welding jig configured to closely adhere the two electrode leads of the facing battery to each other and press the two electrode leads at one side of the two electrode leads, when welding is performed.

It is possible to weld first and second members at various angles and allow melted members to flow onto a welding surface without dripping downward. An ultrasonic welding apparatus includes: a first robot including a holding part configured to hold a first member rotatably and tiltably and a moving part configured to move the robot itself; and a welding main body in which a second member is disposed on the first member held by the holding part of the first robot and which perform welding by vibrating the first and second members by an ultrasonic horn.

Additive manufacturing can involve dispensing a powdered material to form a layer of a powder bed on a support surface of a build platform. A portion of the layer of the powder bed may be selectively melted or fused to form one or more temporary walls out of the fused portion of the layer of the powder bed to contain another portion of the layer of the powder bed on the build platform

An assembly includes a first metallic component, a polymeric preassembly device affixed to the first metallic component, and a second metallic component received over the polymeric preassembly device to loosely connect the first metallic component and the second metallic component.

A welded shaped steel manufacturing device for weld-connecting a butt portion of a web member having an end butting perpendicularly against a flange member and thereafter correcting in shape the flange member subjected to thermal deformation caused by heat input during welding, the device includes: a corrective device including flange-member correcting rollers arranged for respective ends of the flange member, each configured to press each end on a web-member side of the flange member so as to correct the thermal deformation over a range of the flange member from each end thereof to the butt portion thereof against the web member, and web-member supporting rollers configured to support a web surface of the web member, wherein the flange-member correcting rollers arranged for the respective ends of the flange member apply independent pressures to the respective ends so as to correct the thermal deformation.

The jig for welding according to the present invention relates to a jig for welding, which is used in a welding process during manufacturing of a secondary battery, and includes a body part, and a protrusion that extends from a surface of the body part, has a size corresponding to an opening of the secondary battery, and is inserted into the opening of the secondary battery in the welding process, wherein a welding hole through which a laser is configured to pass is defined in each of a circumferential portion of the protrusion and a region of the body part which corresponds to a circumferential portion of the protrusion, wherein the protrusion includes a pressing portion that is provided in a peripheral part of the welding hole and presses an object to be welded in the secondary battery.

A system providing an on-site trailer axle manufacturing jig according to the present invention includes a pair of jig horizontal members, a pair of end cross members coupled between the pair of jig horizontal members about opposing ends, a set of support leg members vertically arranged to support the combination of the jig horizontal members and the end cross members, a pair of attachment wheel assemblies adjustable coupled between the jig horizontal members, and an extending shaft coupled to one of the attachment wheel assemblies for receiving a set of balancing weights to act as a counterweight when manufacturing a trailer axle. Each of the support leg members is coupled to a corresponding leveling adjustment leg, and each attachment wheel assembly has an attachment wheel, a spindle chuck, and a wheel mount spindle. A trailer axle is assembled with a spindle inserted into each spindle chuck to align with opposing ends of an axle member during welding.

A spacer assembly and method for using same to fix a first component to a second component are provided. The method includes positioning the first and second spacer segments between the first and second components, the first and second spacer segments each including an inner face, an opposite outer face, and an exterior surface extending along a longitudinal axis between the inner face and the outer face. The exterior surfaces of the first and second spacer segments are coaxially aligned and secured by a securing device such that the inner faces of the first and second spacer segments define supplementary non-perpendicular angles relative to the longitudinal axis and the outer faces of the first and second spacer segments are parallel to one another. The securing device and the first and second spacer segments are removed after the first component is mechanically coupled to the second component.

An additive manufacturing system including a two-dimensional energy patterning system for imaging a powder bed is disclosed. Improved structure formation, part creation and manipulation, use of multiple additive manufacturing systems, and high throughput manufacturing methods suitable for automated or semi-automated factories are also disclosed.

A method of welding a workpiece assembly includes positioning a flange adjacent to a web to form a workpiece assembly having an interface between a flange edge surface and a web side surface, and in which a web edge portion protrudes beyond a flange front surface on a front side of the workpiece assembly. The method additionally includes constraining the flange and the web against movement, and moving a plasma arc welding (PAW) torch, located on the front side of the workpiece assembly, along a lengthwise direction of the interface, while causing a plasma arc to pass through a flange edge portion and the web side surface, and generate molten material that joins the flange to the web.
