Monitoring laser-welded or -soldered seam for quality, welds series of points and takes images to assess heat dissipation from each

Verfahren und Vorrichtung zum Verbinden von mindestens zwei Werkstücken

Process for welding metal bodies

Metal sheets connecting method for e.g. door, of motor vehicle, involves bending end section of outer metal-sheet, placing inner metal sheet on bent end section of outer sheet, and positively connecting end sections with one another

Procedure for connection of joining parts by adhesion useful in auto body construction, comprises applying an adhesive on adhesive surface at a joining part, and bringing and fixing the joining parts together in a desired joining position

Materially joining sheet metal parts for motor vehicle bodies, comprises applying a liquid adhesive on contact surfaces of the sheet metal parts to be connected and in-contact-bringing the sheet metal parts over the contact surfaces

Monitoring quality of laser-welded or -soldered seam, employs camera to take images revealing thermal dissipation immediately after completing each point of seam

Process for preparing a workpiece to be worked with a laser beam, and device for carrying out the process

Method and device for welding workpieces

Method and device for joining at least two workpieces
