Abstract
A method for soldering or welding components in a series production wherein: a fixing seam which connects the components (1, 2) is produced by melting a connecting material (3), which is supplied as an additional material or is formed by a base material of the components (1, 2), along a joint formed by the components (1, 2); and a volume-forming layer of connecting material is deposited onto the fixing seam by melting, or the fixing seam produced by means of the connecting material supplied as an additional material is re-melted.
Claims15
A method for soldering or welding metal body sheets in a series production of vehicle body parts comprising:
- a) producing a fixing seam which connects the components by melting a connecting material, which is supplied as an additional material or is formed by a base material of the components, along a joint formed by the components;
- and
- b) forming a finished connecting seam by melting a volume-forming layer of additional connecting material onto the fixing seam, or re-melting at least a portion of the fixing seam produced by means of the connecting material supplied as an additional material,
- c) wherein the fixing seam and the finished connecting seam are each progressively produced in the longitudinal direction of the joint at a respective production speed, wherein
- d) the production speed of the fixing seam is greater than the production speed of the finished connecting seam, and
- e) wherein the fixing seam is produced in a first joining station and the finished connecting seam is produced in a separate second joining station.
A production line for joining components, the production line comprising:
- a) a conveying line for the components;
- b) a geometry station which is arranged in the conveying line and comprises a tensing means by means of which a group of the components can be tensed relative to each other in a joining position, and a first actuator which is freely movable spatially and comprises a first tool head;
- c) which, for energy-beam soldering or energy-beam welding the components situated in the joining position, comprises a first energy emitter for melting a supplied soldering or welding material or for melting only a base material of the components to be connected to each other;
- d) and a second actuator which is arranged on the conveying line downstream of the geometry station in the conveying direction in a separate station, is freely movable spatially, and comprises a second tool head which, for energy-beam soldering or energy-beam welding, comprises a second energy emitter for melting the same or another soldering or welding material;
- e) wherein at least one of the tool heads comprises a wire guide via which a wire of the soldering or welding material is conveyed in the longitudinal direction of the wire through an outlet of the tool head, and the energy emitter of the at least one of the tool heads is directed towards a tip of the wire.
