The present invention is a laser processing device wherein adhesion of fumes to a lens can be effectively avoided. The laser processing device is provided with a laser scanner provided with protective glass on a laser output opening, and a cylindrical member having a through path through which the laser output via the protective glass passes formed on the center side in the direction of the radius. A cylindrically shaped filter is disposed on an inside wall part of the cylindrical member facing the through path. The cylindrical member discharges a gas into the through path from the filter.

The seam welding apparatus welds a workpiece held by a robot while delivering the workpiece between a pair of electrode rolls. The seam welding apparatus includes a load cell mounted on the robot, for detecting a load imposed along a Y direction which is perpendicular to a pressing direction Z along which the electrode rolls press the workpiece at a weld point and a delivering direction X along which the robot delivers the workpiece at the weld point, a robot controller and an arithmetic unit, a turning mechanism for turning the electrode rolls about the pressing direction Z, and a control device for controlling the turning mechanism to operate depending on the magnitude of the load in the Y direction detected by the load cell.
