Abstract
A method of welding two metal sheets includes providing a first sheet having a first weld surface and a second sheet having a second weld surface. The first sheet has a zinc coating on the first weld surface. The method further includes arranging the first and the second weld surfaces such that the first and the second weld surfaces face each other with a gap therebetween, and irradiating the first and the second weld surfaces with a laser beam. The laser beam is moved with a wobbling motion in a feed direction along an imaginary feed line and perpendicular to the imaginary feed line. A path of the laser beam along the imaginary feed line is of a periodic shape. A width of the path perpendicular to the imaginary feed line is greater than a length of a period of the path along the imaginary feed line.
