An electroslag welding welding guide fixture and its manufacturing method

Abstract

The invention relates to a tooling device for electroslag welding, in particular to an electroslag welding guide clamp and a manufacturing method thereof. The electroslag welding guide clamp comprises a first convex face, a second convex face, a third convex face and a fourth convex face. The electroslag welding guide clamp is characterized in that a junction of the first convex face and the third convex face forms a first concave face, a junction of the second convex face and the third convex face forms a second concave face, a junction of the third convex face and the fourth convex face forms a third concave face, a junction of the fourth convex face and the first concave face forms a fourth concave face, and junctions of the first convex face, the second convex face, the third convex face and the fourth convex face form welding electrode holes. The electroslag welding guide clamp has the advantages that by applying the electroslag welding guide clamp, the technical defect that center of a wire guide pipe aligns at that of a welding bead is overcome, welding accuracy is improved, and welding efficiency is improved.

Description

technical field [0001] The invention relates to a tooling device for electroslag welding, in particular to a guiding fixture device for electroslag welding. Background technique [0002] In the field of building steel structure welding, wire non-melting nozzle electroslag welding machines are generally used to weld box beams, column partitions and panels to ensure full penetration. Due to the high bead height of this type of welding, a longer guide wire tube must be used, but because the weld bead is too deep and the internal light is dark, it is impossible to manually adjust the position of the guide wire tube by visual inspection, and the straightness of the guide wire tube Generally, it cannot be guaranteed. At the same time, there is a problem of irregular deformation of the wire guide tube after being heated in the weld bead, so that the center of the guide wire tube cannot be aligned with the center of the weld bead during the welding process, and the weld seam is not...
