Abstract: A consumable welding electrode, a method of electoslag welding using such an electrode, and an electroslag weld deposit produced by the use of the welding electrode and welding method of the invention. The welding electrode, while not restricted thereto, has particular utility for use in the electroslag welding of high tensile strength members formed of low alloy steels of the family of steels which includes American Society of Testing Materials designation ASTM A516-76. The welding electrode has a chemical composition in which the carbon content and contaminants have been reduced to the very minimum possible, resulting in greater impact strength of the electroslag weld deposit. The welding electrode includes constituents of manganese, silicon, nickel and iron.

Abstract: A method of electroslag welding for use in the electroslag welding of high tensile strength members formed of low alloy steels of the family of steels which includes American Society of Testing Materials designation ASTM A516-76. The welding electrode used in the method has a chemical composition in which the carbon content and contaminants have been reduced to the very minimum possible, resulting in greater impact strength of the electroslag weld deposit. The welding electrode includes constituents of manganese, silicon, nickel and iron. The nickel and manganese content of the electrode are so proportioned as to compensate for loss of tensile strength in the electroslag weld deposit which would otherwise be caused by the minimal carbon content of the welding electrode, this proportioning of the nickel and manganese content of the welding electrode also maximizing impact strength and ductility of the weld deposit.

Abstract: A nozzle structure of electroslag welding machines for use in welding planks having heavier thicknesses compared to previously electroslag welded planks, and having as much as 800 mm thicknesses, in which the nozzle structure is formed of a plurality of bent pipes rigidly connected with each other to form a fan-shaped nozzle structure. A plurality of wires are continuously fed through each of the bent pipes into a weld gap formed by faces of planks to be welded.

Abstract: A method for electroslag welding of metals whose density is less than that f welding fluxes, is provided. The method is based on floating-up of drops of molten metal of the edges being welded and of the electrode in a slag whose density exceeds that of the metal. The floating-up metal drops form a metal bath on the surface of the slag bath, and crystallization of the metal bath produces a weld. In the course of welding, the electrode metal is fed into the slag bath in the upward direction, while the electrode metal melts and the weld is built up in the downward direction.

Abstract: A method for regulating the parameters of thermal cycles in electroslag welding in which the entire area of the zone affected by heating is cooled. The area is limited by isotherms of maximum heating temperatures within an interval from temperatures close to the melting temperature point up to a temperature A.sub.1. The cooling is effected so that the cooling rate would increase in the direction of movement away from the area heated up to the melting point towards the area heated up to the temperature A.sub.1. The device for realizing the method of regulating the parameters of thermal cycles has jets secured on the side and bottom faces of the slide block, with outlet spraying nozzles for the jets located such that the cooling medium flowing out from those nozzles would cool the entire surface of the metal of the seam and the zone subject to heating effect the surface is limited by the isotherms of maximum heating temperatures within an interval from the melting point up to the temperature A.sub.1.

Abstract: The present disclosure relates to an overhead submerged arc welding process wherein a flux for the submerged arc welding is supplied from the underside of the welding line while at the same time a consumable electrode is supplied from the underside of the welding line, the process being characterized by maintaining the interrelationship between a flux supply cylinder and the plates to be welded such that the length from the under surfaces of the plates to be welded to the upper end of the open flux supply cylinder and the diameter D of the opening at the end of the flux supply cylinder is represented by the formula 2.ltoreq.D/I.ltoreq.15.

By providing one or, depending on the thickness of the sheet steel panels, more than one pair of closely spaced wire electrodes in the weld gap with the simultaneous introduction of additional filler metal carrying no current, preferably in the form of a metal powder, disadvantages associated with known methods may be avoided.

Abstract: In pipes and the like of relatively heavy section, a boss is formed on the side of the pipe or section by drilling a hole in the pipe, forming a mold around the hole with the hole in relatively vertical position and depositing in the mold and against the walls of the pipe, thereby joining to those walls, electroslag metal which forms a boss on the pipe.

Abstract: A consumable assembly consituting the source of metal for welding by the electroslag process, comprising a stainless steel guide sleeve, a tube of copper inside the guide sleeve, and a weld wire inside the copper tube.

Abstract: The present invention relates to a method of vertically upward arc welding for vertical and inclined joints. More particularly, the invention relates to a vertically upward arc welding method which includes the step of feeding a strip electrode in a direction at which the plane including the width direction of the strip electrode crosses the weld line, generating an arc from the strip electrode to a molten pool and/or an upper base metal disposed above the surface of the molten pool, melting the upper base metal disposed above a sliding backing shoe on the front surface side of the groove, and performing welding by expanding the groove and simultaneously dropping the molten metal onto the lower molten pool and depositing the same therein.

Abstract: Sections of cast manganese steel, or manganese steel to be interfaced to another steel, are joined by electroslag welding. Metallurgical limitations, operating parameters and physical attributes of the guide tube are imposed to retard embrittlement of the base metal and weld metal as well, to prevent tearing, to assure satisfactory ductility, and to preserve the integrity of the austenitic manganese steel in the weld metal.

Abstract: A welding method for forming a fillet welded joint including the steps of placing an abutting edge of a first metal member onto a surface of a second metal member at generally right angles thereto, the abutting edge having a series of alternating lands and slots extending through the entire thickness of the first member, and arc welding employing a consumable electrode to form a fully penetrated fillet weld from one side only of the joint with the weld filling the slots and melting the lands.

Abstract: A weld bead is disposed between two workpieces to be welded together by feeding the weld metal to a pool which is advancing relative to the workpieces while supporting the pool of weldment from below with a member which simultaneously serves to maintain the spacing of the workpieces and is preferably composed of tungsten. The support member can be constituted as an electrode. The pool-support member and the burner form a unit which is displaced along the welding gap between the workpieces.
