    • PURPOSE: A welding method is provided to reliably fix first and second parts relatively to each other without adding other parts by welding both parts together with a third part like a printed circuit board. CONSTITUTION: In a welding method to weld first and second parts(10,11), energy is supplied to melt a melting area(13) of the first and second parts by laser beam(22). The first part is made from a material for absorbing weakly energy of the laser beam. The first part is made from a material for absorbing strongly the energy of the laser beam. The laser beam passes through the first part toward the second part. At least one stopper(17) for limiting a motion of the first and second parts is disposed outside the melting area. The motion of the first and second parts is restricted to each other by the stopper in welding by pressing the parts by each other after welding the parts. At least one stopper interacts with a third part(12). The third part is pressed by at least one stopper for one of the first parts after welding.
    • 目的:提供一种焊接方法,以可靠地将第一和第二部件彼此相对地固定,而不需要通过将两个部件与诸如印刷电路板的第三部件一起焊接而添加其他部件。 构成:在焊接第一和第二部分(10,11)的焊接方法中,供应能量以通过激光束(22)熔化第一和第二部分的熔化区域(13)。 第一部分由用于吸收激光束的弱能的材料制成。 第一部分由用于强烈吸收激光束的能量的材料制成。 激光束通过第一部分朝向第二部分。 用于限制第一和第二部分的运动的至少一个止动件(17)设置在熔化区域的外部。 第一部分和第二部分的运动在焊接部件之后通过彼此挤压部件而通过焊接中的止动器彼此限制。 至少一个止动件与第三部分(12)相互作用。 第三部分在焊接之后由至少一个用于第一部分的止动件压制。
