A trigger unit (60) converts the reflected light into a second electrical signal and outputs a trigger signal if the level of the second electrical signal is at least a prescribed threshold value. Upon receiving an input of the trigger signal, a laser welding monitor (80) initiates, on the basis of the first electrical signal, a determination of whether laser welding of the material to be welded is being performed normally.

Abstract: This sponge titanium sheet material, which can adequately contact another member, and through which a liquid or gas can satisfactorily flow and diffuse, comprises a titanium or titanium alloy sintered compact, and forms a three-dimensional network structure having through holes which are open in the surface thereof and which are communicated with internal pores, the porosity thereof being in the range of 70-95%, and the average pore diameter being in the range of 50-600 µm, and the sponge titanium sheet material has a flatness F= w/t calculated from the average thickness t and the curvature amount w.
