Abstract
A method and apparatus for horizontal fillet welding of steel plates, particularly coated or painted steel plates, in which two spaced apart welding wires are directed toward the line of intersection of a vertical steel plate and a horizontal steel plate to be welded together so that the centerline defined between the two wires intersects with such line of intersection. The wires are alternately fed toward the line of intersection in such a manner that one of the wires is fed to the vertical plate at a first predetermined rate and the other of the wires is fed to the horizontal plate at a second predetermined rate which is greater than the first rate.
Claims6
A method for horizontal fillet welding of a vertically oriented steel plate to a horizontally oriented steel plate which have been butted together to a T-shape, the welding being conducted along the line of intersection therebetween, the method comprising a single pass of the steps of
- directing a pair of spaced-apart welding wires in the general direction of said line of intersection, each of said wires having a predetermined diameter, said wires being disposed such that one is directed towards the vertically oriented steel plate and the second is directed toward the horizontally oriented steel plate and such that the centerline therebetween intersects with the line of intersection between said plates;
- and
- alternately feeding during the single pass said wires at predetermined time intervals towards said plates;
- and when feeding said wires, feeding said wire directed towards said vertically oriented plate at a rate equal to or less than the rate of feeding said wire directed towards said horizontally oriented plate.
