A galvanized reinforcement beam is continuously formed by uncoiling a roll of galvanized sheet stock in a generally horizontal plane. Protrusions are formed at an upper surface of the sheet stock, which is then roll formed to form a tubular shape with the protrusions abutting a surface of the sheet stock to form venting gaps. The sheet stock is laser welded at the protrusions to continuously form a weld joint, where zinc oxide gas generated from the welding is permitted to escape an interior of the tubular shape through the venting gaps.

A method for producing a sealing ring comprises cutting a sheet-metal strip to a length of a ring circumference using laser cutting; forming the sheet-metal strip into a ring shape having first and second mutually contacting edge surfaces; and joining the first and second mutually contacting edges using laser welding so as to form a substance-to-substance bond.

Disclosed is a manufacturing method of a welded pipe, which includes: bending a stainless steel strip while conveying the stainless steel strip in one direction to thereby form a pipe; and welding a butting part of the formed pipe.

There is provided a method of manufacturing a washer capable of suppressing reduction in a sliding area, which includes: a preparing step of preparing a panel-shaped member N; a cutting step of cutting the panel-shaped member N with a laser L2 to thereby obtain a longitudinal member N1; and a forming step of obtaining an arc-shaped washer by using the longitudinal member N1. The panel-shaped member N has an equal width to a longitudinal width of the longitudinal member N1. The cutting step is a step of cutting the panel-shaped member N from one end to the other end in a width direction to thereby obtain the longitudinal member N1 and the forming step is a step of deforming the longitudinal member N1 into an arc shape so that cut faces of the longitudinal member N1 form an outer peripheral face and an inner peripheral face.

A multi-tubular beam for a vehicle, such as a vehicle structure or a bumper reinforcement, includes an elongated beam formed with a metal sheet. The metal sheet has a central section and outer sections extending along a length of the metal sheet. The outer sections are disposed in opposing directions from the outer edges of the central section to provide adjacent first and second tubular portions. The central section forms a common center wall between the adjacent first and second tubular portions. A first edge portion of the metal sheet is disposed along and in parallel alignment with the center wall. The first edge portion is attached to the center wall at a first weld joint to form the first tubular portion. The first weld joint includes a weld material that extends through a thickness of the center wall and into a thickness of the first edge portion.

A single-use beverage barrel for one-time use, produced from a primarily cylindrical casing part, deep-drawn bottom and lid parts, having an opening in the center of the lid part, which is sealed by a plastic fitting and wherein the casing part is produced from stainless steel and has a wall thickness of 0.8 mm or less and the bottom part and the lid part are also produced from stainless steel and have a wall thickness of 0.8 mm or less.

A process is provided for the continuous production of thin-walled, radially closed hollow profiles composed of nonferrous metals and having a small cross section comprises supply of a flat strip of the metal to a forming apparatus at a first supply speed, the thickness of the strip corresponding to the wall thickness of the hollow profile. The forming apparatus continuous forms the flat strip into a shape corresponding to the hollow profile. After forming, two opposite edges of the flat strip rest flush against one another in a contact region and are continuously welded by means of a laser which emits light having a wavelength of less than 600 nm. The laser heats an area in a welding region having a diameter of less than 20% of the cross-sectional dimension of the hollow profile. The welded hollow profile is taken off from the welding region and taken up in an uptake device.
