Abstract
The present invention relates to a joining method, and more specifically relates to a method for joining different kinds of plates that joins at least two plate members of which materials thereof are different from each other through laser welding. For this, a method for joining different kinds of plates according to an exemplary embodiment of the present invention may include disposing a first plate and a second plate, materials of which are different from each other, such that they are overlapped with each other, and joining the first plate and the second plate by irradiating a laser beam at a predetermined inclination angle and in a regular pattern onto the overlapped portion of the two plates.
Claims13
A method for joining different kinds of plates, comprising:
- disposing a first plate and a second plate, materials thereof being different from each other, such that they are overlapped with each other;
- and
- joining the first plate and second plate by irradiating a laser beam at a predetermine inclination angle and in a regular pattern onto the overlapped portion of the two plates.
A method for joining different kinds of plates, comprising:
- disposing a second plate on a first plate of which a melting point thereof is lower than that of the second plate such that at least parts of them are overlapped with each other;
- regularly irradiating a pulse-type laser beam on the overlapped portion of the first plate and the second plate from an upper portion thereof at a predetermined inclination angle;
- and
- joining the first plate and the second plate through the laser beam irradiation.
