摘要:
A welding torch 10 is provided for use in a Gas Metal Arc Welding (GMAW) process. The welding torch 10 includes a torch body 12, a welding tip 16 extending from the torch body 12, and a detachable nozzle 22 which substantially surrounds the welding tip 16 in use to direct gas around the welding tip 16 and onto a workpiece, the nozzle 22 having a front end which faces the workpiece in use and a rear end which attaches to the torch body 12 in use, in which a ring 24 is provided, the ring 24 being substantially axially fixed to the nozzle 22 at the rear end of the nozzle 22, and the ring 24 being rotatable with respect to the nozzle 22, the ring 24 having a screw thread and the torch body having a corresponding screw thread 26, for fixing the nozzle 22 to the torch body 12.

A welding gun is provided that includes an elongated body having a longitudinal axis, a neck assembly connectable to the elongated body, and a handle including a sleeve portion mounted around and longitudinally fixed relative to the elongated body, and a grasping portion extending lengthwise radially outwardly from the sleeve portion. The welding gun also includes a rotation mechanism including an inner structure fixedly provided along an outer periphery of the elongated body and having a number of circumferentially distributed engaging elements, and an outer structure fixedly provided along an inner periphery of the sleeve portion and having a number of circumferentially distributed engaging elements. The engaging elements of the outer structure cooperate with the engaging elements of the inner structure for releasably locking the elongated body into a plurality of discrete angular positions relative to the sleeve portion about the longitudinal axis.

Die Erfindung betrifft ein Schweißverfahren sowie eine Schweißvorrichtung zum Verbinden von überlappenden Blechen, wobei zunächst das Oberblech (1) der überlappenden Bleche mit einem Lichtbogen (6) zwischen einem fortwährend zugestellten Schweißdraht (3) und dem Oberblech (1) aufgeschmolzen und anschließend die überlappenden Bleche mittels des Schweißdrahtes (3) durchsetzt werden. Mit dem erfindungsgemäßen Verfahren wird eine form- und stoffschlüssige Punktschweißverbindung geschaffen. Die Möglichkeit, marktübliche, weit verbreitete und preisgünstige Schweißvorrichtungen zu verwenden, gewährleistet ein kosteneffektives und zeitsparendes Schweißen. Besonders vorteilhaft ist das Verfahren zum Verbinden artungleicher Werkstoffe geeignet, da die erfindungsgemäß kurzen Schweißzeiten ungünstige metallurgische Wechselwirkungen verhindern.

Automatic welding machine includes: a welding torch (52) mounted to a link actuation device (1) set on a mount (50); and a one-or-more-axes linear motion actuator (55, 56) which causes the link actuation device (1) to advance and retract relative to the mount (50). The link actuation device (1) includes: a proximal end side link hub (2) disposed on the mount (50); a distal end side link hub (3) to which the welding torch (52) is mounted; and three or more link mechanisms (4) configured to couple the distal end side link hub (3) to the proximal end side link hub (2). Each link mechanism (4) includes proximal side and distal side end link members (5, 6) and an intermediate link member (7). Two or more link mechanisms (4) are each provided with a posture changing actuator (20) which arbitrarily changes the posture of the distal end side link hub (3) relative to the proximal end side link hub (2).
摘要:
The invention relates to a hybrid MIG-TIG or MAG-TIG welding device comprising a MIG or MAG welding torch (1) which includes a consumable wire (1a) oriented in a first direction (1b) and which is associated with a TIG welding head (2) comprising a non-consumable electrode (2a) oriented in a second direction (2b), said first and second directions (1b, 2b) being substantially coplanar and forming therebetween an angle (α) of between 5 and 40°. According to the invention, the device further comprises a shoe (5) for assembling the torches (1, 2), which is designed to allow the TIG welding torch (2) to be positioned in at least two predefined positions with respect to the MIG or MAG welding head (1), said positions including: a first position in which the end (2c) of the non-consumable electrode (2a) is situated at a first distance (D) from the first direction (1b), and a second position in which the end (2c) of the non-consumable electrode (2a) is situated at a second distance (D') from the first direction (1b), the second distance (D') being greater than the first distance (D).
