A metal joiner system includes a power source and a metal joiner. The metal joiner includes a cleaning header, a cutting header, a joining header, and a joint finisher, each of which are communicatively coupled to the power source. The cutting header and cleaning header are configured to direct a first laser beam to prepare a joining region, and the joining header is configured to direct a second laser beam to form a joint in the joining region. A method of joining a metal substrates includes forming a joining region in abutting metal substrates, directing the first laser beam onto the joining region in a joint preparation stage, and directing the second laser beam onto the joining region to form a weld. A product of a metal joiner, a weld, has a portion of weld metal removed at the weld start and the weld crater regions.

Provided is a method of manufacturing a molded product that can reduce problems on a reinforcing plate during pressing. In one aspect of the present disclosure, the method of manufacturing a molded product includes welding a first metal plate overlaid with a second metal plate to the second metal plate; and pressing the first metal plate and the second metal plate together. In the pressing, a base surface and a wall surface are formed on the first metal plate; the wall surface is disposed to cross the base surface. In the welding, a first welding is performed on a reinforcing portion of the second metal plate that is overlaid on an area of the first metal plate that is formed into the wall surface; and subsequently, a second welding is performed in a direction crossing a direction of the first welding.

A welding method materially cohesively bonding at least two components using at least one additive material. A welding seam is produced with a seam course between a seam start and a seam end. The process is controlled using at least one control unit, at least one external physical welding seam property of the welding seam is influenced by a control parameter of the control unit, and information is included in the control parameter. The information, during the process is stored in the welding seam between a start point and an end point in the seam course using the at least one external physical welding seam property so that the information can be read, optically and/or haptically, from a sequence of the at least one detectable external physical welding seam property along the course of the seam in the region between the start point and the end point.

The invention relates to methods for laser welding a first and a second workpiece portion with a laser beam that is guided using a laser machining head along a joining gap formed between the workpiece portions, in which method the laser beam is focused and a filler is lined up with the joining gap. At least one gap width of the joining gap of the workpiece portions to be welded is detected and evaluated along the course of the joining gap and compared with at least a first and a second gap measurement. If a detected gap width is within the first gap measurement, the feeding of the filler to the joining gap is stopped and a beam profile of the laser beam is set with a point or annular focus, and if a detected gap width is within the second gap measurement, a feeding of the filler is actuated.
