Abstract
Disclosed therein is a multi-axis laser welding head for a spacer grid, which is one of essential components of a nuclear fuel assembly. More particularly, the multi-axis laser welding head for the spacer grid can be operated more smoothly and variously during the welding of the spacer grid to thereby weld the spacer grid more exactly and precisely. For this, the multi-axis laser welding head includes a welding head having a movement within a predetermined angle like the back and forth swing of the pendulum, and can irradiate a laser beam in various directions by having additional axis in comparison with the prior art.
