Embodiment 1

[0026] Example 1. The present invention provides a high-efficiency submerged arc welding welding pad 11 used for high-efficiency submerged arc automatic welding and semi-automatic single-sided welding for double-sided forming. The high-efficiency submerged arc welding welding pad 11 is composed of several ceramic welding pad blocks 1 connected end to end, the bottom of the welding pad is wrapped in a strip-shaped reinforcement shell 2, and a layer of glass fiber tape 3 matching the size of the welding pad is provided on the upper surface of the welding pad.

[0027] A centering line 4 is provided on the glass fiber tape. In this embodiment, a red fiber line is embedded on the center axis of the glass fiber tape as the center line.

[0028] The glass fiber tape 3 is an alkali-free glass fiber tape 3 .

[0029] The glass fiber tape 3 has a thickness of 0.8-1.2 mm.

[0030] The glass fiber tape 3 is a rectangle, the length of the rectangle matches the length of the pad 11 , an...

Abstract

The invention provides an efficient submerged-arc welding gasket which comprises a plurality of ceramic welding gaskets connected end to end. The bottom of the welding gasket is packaged in a strip strengthening casing, and a glass fiber tape with the size being matched with that of the welding gasket is arranged on the upper surface of the welding gasket. The invention further provides a manufacture method and an application method of the efficient submerged-arc welding gasket. As the submerged-arc welding gasket is connected and mounted into the strengthening casing, the submerged-arc welding gasket has certain extrusion resistance capability, when small plate edge difference exists in a welding connector, the gasket can not be damaged during the process of applying external force to correct the plate edge difference. During the process of one side welding, welding slag formed by burning the gasket through a welding arc can be molten into the slag of a same slag system with the welding slag of welding wires, iron powder and welding fluid, and back weld can be guaranteed to achieve required mechanical property and chemical elements. The efficient submerged-arc welding gasket accelerates the welding speed, saves welding material and guarantees the weld quality.

Description

technical field [0001] The invention belongs to the field of welding, in particular to the field of arc welding materials for steel. [0002] Background technique [0003] With the rapid development of my country's industry, the shipbuilding industry is advancing by leaps and bounds, and high-rise and super high-rise steel structure buildings are emerging. The larger the tonnage of the ship and the taller the building, the thicker the steel used. The production efficiency of the current submerged arc single-sided welding can no longer meet the needs of the development of welding production. The welding production efficiency of high-efficiency submerged arc automatic single-sided welding is twice that of submerged arc automatic welding; it is CO 2 The welding production efficiency of flux-cored wire semi-automatic single-sided welding is 10 to 15 times higher. In order to improve the production efficiency of large-thickness steel butt joints, the technology of high-effici...
