LAP WELDING WITH DESIGNED GAP FOR INCREASED JOINT STRENGTH

摘要

A method of welding a first piece to a second piece by laser welding is disclosed. The first piece includes a central portion between two outer portions. The method comprises the step of placing the first piece adjacent the second piece, where the central portion of the first piece is a distance from the second piece, and the outer portions of the first piece are flush with the second piece. The method also comprises the step of applying a laser beam to the central portion toward the second piece. Material from the first piece combines with material from the second piece to form a welded material. A shear section of the welded material extends between the first and second pieces. A width of the shear section is greater than a width of the welded material in the first piece.
