Abstract

TO IMPROVE AND FURTHER DEVELOP THE HEAT TREATMENT OF THE WELD AND THE JOINING WELD REGIONS (6, 7) BEFORE AND BEHIND THE ACTUAL WELDING BY MEANS OF A LASER, WHICH IS CARRIED OUT DURING WELDING OF STEEL SHEETS (2) TO MINIMIZE THE RISK OF CRACK FORMATION OR ALTERATION OF THE MICROSTRUCTURE IN THE REGION OF THE WELD, IT IS PROPOSED ACCORDING TO THE INVENTION THAT THE HEATING OF THE REGION OF THE WELD (6, 7) BE CARRIED OUT BY MEANS OF A MULTIPLY STEPPED LINE INDUCTOR (4, 5) WHICH CAN BE SET IN A DEFINED WAY AND HAS ZONES OF DIFFERENT POWER DENSITIES AND IS CONFIGURED WITH A MULTIPLE DIVISION OF ITS CONDUCTOR LOOP LENGTHS AND/OR WITH DIFFERENT PLATING OF THE CONDUCTOR LOOPS AND/OR WITH A PLURALITY OF SPACING STEPS FROM THE STEEL STRIP (2). HERE, A STEEPER TEMPERATURE RISE OCCURS IN THE FIRST HEATING STAGE THAN IN THE SUBSEQUENT HEATING STAGE.
