Abstract:
Method for joining a first and a second steel blanks, at least one of the blanks comprising aluminium. The method comprises providing a support being made of a magnetic material for each blank, the supports being arranged distanced apart by a central space; providing a coil winding around one support, arranging the first blank on one support and the second blank on the other support, such that a butt end of the first blank that is facing the second blank is brought into contact with a butt end of the second blank that is facing the first blank defining a contacting area that closes a path for magnetic flux. The method further comprises applying a laser beam onto the contacting area, while applying an alternating current to the coil winding, wherein an alternating magnetic field is created across the contacting area in a direction substantially in-line with the blanks.
