Title:
WELDED PORTION INSPECTION DEVICE AND INSPECTION METHOD
Document Type and Number:
Japanese Patent JP2014195822
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a welded portion inspection device and a welded portion inspection method capable of accurately inspecting a welded sate of a welded portion of a workpiece in remote welding for welding a workpiece with, for example, the workpiece being distant from a laser torch.SOLUTION: In the welded portion inspection device, welding laser beam L1 is emitted along welding trajectories C11 and C12 set to workpieces W1 and W2, respectively or inspection laser beam L5 is emitted along scan trajectories C51 and C52 set to a molten weld pool Y1 of the workpieces W1 and W2 welded by the welding laser beam L1. The welded portion inspection device receives return light L2 containing reflected light by the molten weld pool Y1 of the workpieces, steam emitted light generated by molten steam of the workpieces, and heat radiation light radiated from the molten weld pool Y1 of the workpieces, and inspects a welded state of a welded portion of each of the workpieces on the basis of a change in an intensity of the received return light L2.
