Method of electroslag welding with a plate electrode

A method of electroslag welding with a plate electrode, including the steps of positioning component parts to be welded with a gap between the component parts;

• introducing a plate electrode into the gap;
• and melting the electrode and the edges of the component parts by the heat of electrically heated slag to establish an upwardly moving welding bath, the side portions of the surface of the welding bath being formed under movable shoulders of non-molten metal, said shoulders forming during the course of melting of the edges of the component parts, wherein the improvement comprises the component parts to be welded being brought together to form a gap between the component parts such that the area "B" of the gap relates to the area "A" of the horizontal cross-section of the electrode and to the area "C" of the projection of the surface of the welding bath to the a horizontal plane as A:B:C=1:(1.2 to 1.5):(2.5 to 4.5) to maintain an angle of deflection of the welding bath within the range of 0.degree. to 15.degree. in relation to the horizontal plane with the the movable shoulders limiting the vertical movement of the side portions of the surface of the welding bath, which side portions amounting to 40 to 75% of the area of the surface of the welding bath, and with a magnetic field of the electrode.
