摘要： Die Erfindung betrifft ein Verfahren und eine Vorrichtung (1) zum Schweißen eines Werkstücks (2), wobei mit Hilfe eines gepulsten Schweißstroms ( I S ) ein Lichtbogen (LB) erzeugt wird, und der Lichtbogen (LB) mit Hilfe eines Magnetfelds, das durch eine von einem Strom (I A ) durchflossenen Spule (3) erzeugt wird, abgelenkt wird. Erfindungsgemäß wird der Strom (I A ) durch die Spule (3) zur Erzeugung des Magnetfels zur Ablenkung des Lichtbogens (LB) synchron und gegengleich zum Schweißstrom (I S ) angesteuert.

摘要： The purpose of the present invention is, in gas shielded arc welding using an active gas and flux-cored wire with primer-coated steel plates as a base material, to suppress occurrences of poor appearance in welded parts caused by pores originating in the primer. A welding method for a welded article positions a first steel plate and a second steel plate formed from primer-coated steel plates in a T shape and welds each of corner parts formed in two locations. Using flux-cored wire (100), which is formed by filling the inside of a steel outside skin with flux, and a shielding gas (carbon dioxide gas), a welding pool (400) is formed in the corner part by supplying a welding current to the corner part via an arc from the flux-cored wire (100) by means of the shielding gas; additionally, an alternating magnetic field is applied to the welding pool, and the welding current and the alternating magnetic field are set such that the welding current (A) and the magnetic flux density (mT) for the alternating magnetic field have a relationship of 20000 ‰¤ welding current × magnetic flux density ‰¤ 30000.

摘要： The present invention relates to a method of welding at least one work piece in at least one location, using at least one arc generating element (12), such as a cathode, the method comprising: • - welding the work piece at the location of the arc generating element (12); • - moving the arc generating element (12) along a path of welding and therewith the location of welding; and • - during welding, decreasing magnetic fields in the work piece or between work pieces, by locally suppressing magnetic fields at least partially at or near the location of the arc generating element. The present invention further also relates to a corresponding welding device. The welding device (9) comprises a carriage (10) adapted to move along a path of welding relative to the work piece and therewith a location of welding, and having a holder (11) accommodating at least in use an arc generating element (12); and a device (6) on the carriage, which device is adapted to locally decrease magnetic fields in the work piece or between work pieces, by locally suppressing magnetic fields at least partially at the location of the arc generating element.
