  • Patent number: 6861611
    Abstract: A weld checking apparatus for a laser welding machine having a welding head triggering laser beam to a welding object includes an auxiliary flash intercepting plate removably mounted on a flexible arm installed on the welding head to intercept a flash generated during a laser welding process, a weld-checking/eye-protecting glass assembly disposed on a center portion of the auxiliary flash intercepting plate to display a weld portion in an enlarged scale during the welding process while intercepting the flash by being opened and closed in synchronization with a laser beam trigger speed of the welding head, and an open/close control part for generating a trigger pulse and an open/close pulse synchronized with the trigger pulse and for providing the open/close pulse to the weld-checking/eye-protecting glass through the electric cable 50 to open and close the weld-checking/eye-protecting glass assembly.
