Abstract
A fusion welding method includes the steps of: generating a hybrid laser beam obtained by mixing a low-intensity laser beam with a first high-intensity laser beam and a second high-intensity laser beam; moving the hybrid laser beam along a gap between a first member and a second member; and melting the first member and the second member in the periphery of the gap with the hybrid laser beam, and filling the gap with the melt of the first member and the melt of the second member to weld the first member and the second member, wherein the first high-intensity laser beam is applied to the area of the first member to which the low-intensity laser beam is applied, and the second high-intensity laser beam is applied to the area of the second member to which the low-intensity laser beam is applied.
