The present disclosure includes a laser welding method in which a joint surface between a plurality of workpiece members is welded by radiating laser beam LB, and a locus of laser beam LB is controlled so as to perform wobbling scanning Sw by a combination of scanning motion Sa moving along first direction x parallel to the joint surface and swing motion Sb including first swing component Bx along first direction x and second swing component By along second direction y perpendicular to first direction x, the method including a defect determination step of determining occurrence of a welding defect; and an output control step of increasing or decreasing an output of laser beam LB when laser beam LB is radiated again toward the welding defect in a case where the welding defect occurs.

A housing component includes a flange defining a center point and having an end face formed with microstructures in a first region and a second region to increase a local friction coefficient. The microstructures have each a blade shape with a cutting line, the cutting line in the first region being arranged concentrically about a first local center point, and the cutting line in the second region being arranged concentrically about a second local center point. The first and second local center points have different radial distances from the center point of the flange.

A method for marking, at the outlet of a forming machine using a laser beam, a marking area on hot glass containers comprises determining the longitudinal and transverse positions of the marking area of each container by positioning a first optical axis of a first light sensor and a second optical axis of a second light sensor in a non-parallel manner to each other, in a detection plane parallel to the conveying plane of the containers, detecting the instant of intersection or disengagement, by a container, of the first optical axis and the instant of intersection or disengagement, by a container, of the second optical axis, and calculating said transverse and longitudinal positions from these instants and in consideration of a known or constant speed of translation of the containers. The method can determine the marking instant for each container running past the laser apparatus.

Disclosed here is a method of making a golf club head. The method comprises steps of laser ablating a second-part surface of a second part of the golf club head such that a second-part ablated surface is formed in the second part, and bonding together a first-part surface, of a first part of the golf club head, and the second-part ablated surface of the second part of the golf club head.

A hardfacing metal composition and method of restoring worn work string tubing by application of a hardfacing metal to the worn regions of the work string tubing.

In one aspect, the present invention relates to a control unit (RE) for calculating a spatially and time-resolved, combined setpoint data set (SW-DS) for open- and/or closed-loop control of a laser cutting process during laser cutting with a laser cutting machine (L), wherein a processor (P) is intended to access a process model (PM) in a first memory (SI) via a process interface (P-SS) and a machine model (MM) in a second memory (S2) via a machine interface (M-SS) in order, on the basis of an estimated status data of the laser cutting process and the movement process, to calculate the spatially and time-resolved, combined setpoint data set (SW-DS) with coordinated setpoints for the laser cutting process and setpoints for the movement process, taking into account the read-in sensor data.

That is, a battery case comprised of a container body and a container lid, wherein the container body and the container lid are each comprised of a plated steel sheet, a joint part between the container and the container lid is comprised of a plating welded part containing a main constituent component of the plating of the plated steel sheet in 60 mass% or more and a steel sheet welded part containing the main constituent component of the plating in less than 60 mass%, and the plating welded part has a length of 0.5 .Math.m or more and less than 1.0 mm in a joint longitudinal direction.

Provided is a battery assembly assembling method, which may include: acquiring a pressing displacement amount of a press; controlling a damper to clamp a battery assembly if an absolute value of a difference between the pressing displacement amount and a standard pressing displacement amount is less than or equal to a preset threshold; acquiring a first actual displacement amount and a first clamping force of the damper; and completing assembling if an absolute value of a difference between the first actual displacement amount and a first standard displacement amount is less than or equal to a first displacement threshold, and an absolute value of a difference between the first clamping force and a first standard clamping force is less than or equal to a first clamping force threshold.

The disclosure provides a wheel. The wheel includes: a rim (10), a surface of an axial end of the rim (10) forming a first connecting surface (11); a spoke (20), a part of a surface of an axial end of the spoke (20) forming a second connecting surface (21), wherein the spoke (20) is laser welded with the first connecting surface (11) by the second connecting surface (21); and a welding bead structure (100) for fixedly connecting the rim (10) and the spoke (20) is formed at a contact position between the first connecting surface (11) and the second connecting surface (21), and the welding bead structure (100) is formed by a part of the rim (10) and a part of the spoke (20) being melted and then connected.

A fixture for facilitating the serial engraving of a plurality of cylindrical objects such as glasses or mugs mounted on individual serially arranged stations along a master base plate. Each station includes a drive structure and, spaced therefrom, a passive support structure. The two structures in each station can be gang-adjusted for object length. In addition, the support structures can be height-adjusted to level the engraved surfaces of tapered objects. All of the drive structures include drive wheel pairs and all are driven by a single stepper motor via a single shaft and individual belt and pulley systems.
