摘要： A method comprising an arc ignition phase (IP), an arc-stabilizing phase (AP) and a stable arc phase (SP). The arc stabilizing phase comprises an initial sub-phase (IS) comprising the step of feeding at least one hot wire (4, 12) at constant feed speed and a main sub-phase (MS) comprising the steps of feeding said hot wire at constant feed speed and feeding at least one cold wire (22) at constant feed speed. The stable arc phase comprises the steps of continuously adjusting the feed speed of the hot wire and continuously adjusting the feed speed of the cold wire. The invention also relates to a welding apparatus (1) for carrying out the method. The welding apparatus comprises a hot wire feeding means (150), a contact means (2), a cold wire feeding means (35) and a control unit (31). The control unit is adapted to control said hot wire feeding means to feed the hot wire at a constant feed speed during the initial sub-phase, feed the hot wire at a constant feed speed during the main sub-phase and to continuously during the stable arc phase adjust the feed speed of the hot wire. The control unit is adapted to control said cold wire feeding means to feed the cold wire at a constant feed speed during the main sub-phase and continuously during the stable arc phase adjust the cold wire feed speed.

摘要： The invention relates to a method for submerged arc welding comprising the steps of guiding a first hot wire (4; 4a, 4b) towards a work piece and guiding a cold wire (22; 22a, 22b) at a variable feed speed. The method further comprises the steps of continuously measuring, during a welding phase, at least a first active welding parameter related to at least said first hot wire (4; 4a, 4b) adjusting the cold wire (22; 22a, 22b) feed speed in dependence on at least first active welding parameter variations, to maintain high welding stability and high weld quality. The invention also relates to a system (9) for carrying out the method. The system (9) comprises hot wire feeding means (150) for feeding a first hot wire (4; 4a, 4b) towards a work piece and cold wire feeding means (35) for feeding a cold wire (22; 22a, 22b) at a variable cold wire (22; 22a, 22b) feed speed and a control unit (31) for controlling the second wire feeding means (35). The system (9) also comprises measuring means (27) adapted to continuously measure at least a first active welding parameter related to said first hot wire (4; 4a, 4b). The control unit (31) determines target values for the cold wire (22; 22a, 22b) feed speed, each target value corresponding to a first active welding parameter value and controls said second wire feeding means (35) to adjust said cold wire (22; 22a, 22b) feed speed to said target values.

摘要： A contact tip (1) for gas metal-arc welding comprising: - A body (3) of a metal material with a tubular base portion (4) and two or more fingers (5a, 5b) extending in the axial direction from a front end of the base portion; - At least one wire-feed conduit (7) extending axially through the body, in which a welding wire is to be received and fed; - slots (10a, 10b) arranged between the fingers in order to space these apart, and - A spring means (11) surrounding the fingers and exerting a radially acting spring force on the fingers of such strength that the fingers, when cool, are kept spaced apart, such that no pressure will be exerted on the casing surface of a welding wire introduced in the wire-feed conduit, and when heated to a temperature above the softening temperature of the metal material, are compressed by the spring force radially inward in order to exert pressure on the casing surface of a welding wire received in the wire-feed conduit.
