Abstract
For the successive welding of the joints of consecutive links forming a link chain, the chain is advanced in a chain welding machine to bring a link to be welded directly below a welding position; the two links flanking the link to be welded are aligned in a common plane of alignment while a tensioning force is applied to the chain parallel to the direction of chain advance. Thereafter, the link to be welded is raised into a welding position in a plane disposed at 90.degree. to the plane of alignment. Subsequently, the link is immobilized in the welding position and its joint is welded. Upon completion of the welding step, the just-welded link is lowered from the welding position.
Claims4
A method for the successive welding of the joints of consecutive links forming a link chain, comprising the following steps:
- a. advancing the chain for bringing a link to be welded directly below a welding position;
- b. applying a tensioning force to said chain parallel to the direction of chain advance;
- c. during step (b), guiding the two links flanking the link to be welded into a common plane of alignment for effecting a setting of said link to be welded, by the tensioning force, into a plane disposed at 90.degree. to said plane of alignment;
- d. raising said link to be welded into a welding position in a plane disposed at 90.degree. to said plane of alignment;
- e. firmly maintaining in the welding position the link to be welded;
- f. welding the link in the welding position;
- and
- g. subsequent to step (f), lowering the just-welded link from the welding position.
