PURPOSE: To reduce welding work time by a large margin by outputting a control signal based on an information signal obtained with a groove detection means.
CONSTITUTION: Secondary electrons of a detecting electron beam 2 reflected from an object 3 to be welded is detected with a detecting operation for a groove 4 and information signals on the groove position and the groove width of the object 3 are obtained with a groove detection means 70. The obtained information signals are inputted to an operation circuit section 60 from which control signals calculated based on the information signals are outputted. A control device K is controlled with the control signals outputted from the operation circuit section 60. The control device K also drive-controls a welding means which irradiates an electron beam 2 for welding onto the groove 4 of the object 3 to be welded on a movement path corrected corresponding to the groove position by means of the welding means.
