A method for butt welding of flat metal blanks in a welding machine, where two metal blanks are placed on a conveyor unit by feed devices and secured by holding means. Two edges of two metal blanks to be welded together are placed together to form a butt joint with the smallest possible gap and then welded together using a welding laser. The gap width is measured and controlled by means of the measured values from the welding process. The gap width is measured by means of the reflected-light method and the true gap width by means of the transmitted light method in such a way that the missing area and the missing volume in the gap can be estimated accurately.

A laser irradiation apparatus (1) according to one embodiment irradiates a workpiece (16) with a laser beam (15) while conveying the workpiece (16) caused to float with the use of a flotation unit (10). The flotation unit (10) includes precision float regions (11a, 11b) and rough float regions (13a to 13j). The precision float regions (11a, 11b) are configured to cause the workpiece (16) to float by utilizing ejection and suction of a gas, and the rough float regions are configured to cause the workpiece (16) to float by utilizing ejection of a gas without suction of a gas.

A method for butt-welding of sheet metal, especially bodywork in the motor vehicle industry, where at least two flat workpieces with any desired contours are fed to a machining process. In a first sub-process, the workpieces are positioned in relation to one another forming a minimal gap and secured in place with holding means. In another sub-process, the position and width of the gap are measured continuously immediately before welding together and the measurements are used to control a laser welding head. The laser welding head is fit with a rotatable twin-spot lens, where the relative alignment of a main spot to an auxiliary spot is controlled depending on the absolute position of the gap and the gap width during the welding process while the processing lens of the laser welding head is rotated around the laser beam axis with the angle of rotation alpha.

Provided is a welding apparatus having a fume elimination function. The welding apparatus efficiently eliminates fume generated while a welding object is being welded using a laser.

A joining apparatus includes a pressor that cause the first joint target portion and the second joint target portion to butt against each other, a workpiece moving organizer that moves the first workpiece and the second workpiece along an extending direction of the first joint target portion and the second target portion, a separator that temporarily separates the first joint target portion and the second joint target portion from each other by deforming a part of a butting site between the first joint target portion and the second joint target portion; and a laser irradiator that irradiates a site at which the first joint target portion and the second joint target portion separated from each other approach each other again, with laser light on a downstream side of the separator in a moving direction of the first workpiece and the second workpiece.

A method for manufacturing a container product is disclosed. The method includes filling a container with contents; forming information on the container, the information including a number, a letter, and an image, the information being formed by a first pattern, the first pattern being made up of a collection of second patterns; and heating or cooling the container before or after the forming of the information on the container.

Provided is an electrode sheet manufacturing apparatus that forms an electrode sheet by cutting a sheet stack including an electrode composite material layer and a separator provided on the electrode composite material layer. The electrode sheet manufacturing apparatus includes a laser irradiation device that irradiates the sheet stack with a first laser beam having a wavelength to be absorbed by the separator and a second laser beam having a wavelength to be absorbed by the electrode composite material layer, and a controller that controls driving of the laser irradiation device. The controller moves an irradiation position of the first laser beam relative to the sheet stack and moves an irradiation position of the second laser beam so as to follow a track of the irradiation position of the first laser beam.
