The apparatus (1) for welding meander-shaped flowing pipes (12) having straight sections and curved sections onto a sheet metal plate (15), comprises a laser device (5), with which a laser light beam is guidable in an area of a contact line of the pipes and the sheet metal plate to weld the pipe onto the sheet metal plate in a point-wise manner, a pressing element (4) to press and guide the pipe onto the sheet metal plate during the movement of the welding device, a first part processable along the pipes and a second part connected to the first part, and first control element. The apparatus (1) for welding meander-shaped flowing pipes (12) having straight sections and curved sections onto a sheet metal plate (15), comprises a laser device (5), with which a laser light beam is guidable in an area of a contact line of the pipes and the sheet metal plate to weld the pipe onto the sheet metal plate in a point-wise manner, a pressing element (4) to press and guide the pipe onto the sheet metal plate during the movement of the welding device, a first part processable along the pipes and a second part connected to the first part, where the pressing element is mounted at the second part, a first control element, with which the second part is bringable relative to the first part alternatively in a fixed or in a horizontally displaceable position, a second control element, a regulating device, two vertically extending guiding elements, and a holding unit, which exerts force acting at the first part against a shear force of the first part and the second part when the holding unit is freely vertically displaceable. The first part is mounted in a vertically displaceable manner. The second part is fixed to the first part. The holding unit is a piston-cylinder unit. The control elements are piston-cylinder units. Two laser devices are provided at the second part. The guiding elements are arranged upstream to the pressing element in the movement direction and are selectively adjustable on the pipe. The regulating device triggers an adjustment of the vertically extending guiding elements when the welding device reaches to the straight section, and triggers a folding down of the vertically extending guiding elements when the welding device reaches to the curved section. The pressing element is formed as rotatable roller, which has a cross-sectional profile with an outer V-shaped groove and a central circular area, which passes in a straight area at the both sides. An independent claim is included for a method for welding meander-shaped flowing pipes having straight sections and curved sections onto a sheet metal plate. |
