摘要： The friction stir welding head (10) presented herein includes a head housing (100) and an axle (202). The head housing (100) extends from a top end (102) to an open bottom end (104) and defines a bore (106) extending between the top end and the open bottom end. The axle (202) is coaxial with and rotatable within the bore (106). The axle (202) is also laterally secured within the head housing (100) and axially movable with respect to the head housing. Still further, the axle (202) includes an engagement end (204) that extends beyond the open bottom end (104) of the head housing (100). The engagement end (204) supports a friction stir welding tool (280) that is configured to rotate with the axle (202) to effectuate friction stir welding operations. The friction stir welding head (10) may also include a load cell (250) configured to generate load signals in response to axial movement of the axle (202).

摘要： The present application relates to an electric arc welding method to be used with an arc welding arrangement (1) comprising a first power source, a first electrode (2) connected to said first power source, and a second electrode (7), said first electrode (2) being adapted to generate a weld pool (28) via a first electric arc present within a first arc region (31) and said second electrode (7) being adapted to generate said weld pool via a second electric arc present within a second arc region. The first electrode (2) is operated at welding parameters adapted to maintain said first arc ignited. The second electrode (7) is operated at welding parameters adapted to ensure that excess energy from at least said first electrode (2) is required to maintain said second arc ignited. The method comprises the step of feeding said second electrode (7) so that it is allowed to consume excess energy from said first electrode (2) to maintain said second arc ignited. The invention also relates to an arc welding arrangement (1) for carrying out the method.

摘要： A welding device and a method for automatic multiple-bead welding, wherein a line illumination member is arranged to illuminate the joint by scanning a light beam across the joint line. A camera is arranged for the registration of line images of the joint when it is illuminated with the scanned light beam. The locations of the edges of the joint are determined by means of triangulation based on the registered line image. The welding device can include a stereo image member arranged to register photometric stereo images of the joint substantially simultaneously with the registration of the line images. The welding device is arranged to, during welding of a weld joint with a plurality of weld beads, control the welding head in dependence on both stereo images and line images.
