Abstract

The invention discloses a tool for arc striking and quenching during submerged arc welding. The tool comprises a connecting piece and a ceramic backing, wherein the connecting piece comprises at leasttwo plate bodies which abut against and splice each other; and one end face of the ceramic backing is used for abutting against the end face of base metal to be welded, and the other end face of theceramic backing is used for abutting against the end face of the connecting piece. When the connecting piece of the tool is manufactured, no groove abutting against a weld groove needs to be formed bythe processes of turning and milling, only an abutting end face needs to be machined, and the manufacture process is simplified. The rapid construction of an automatic production line for fillet weldsubmerged arc of the base metal to be welded can be normalized, so that the trouble of frequent assembly and welding is reduced, the quality defects caused by cutting arc striking and quenching plates on the two sides are reduced, management and operation normalization is perfected, meanwhile the working efficiency is greatly improved, and further the equipment productivity is increased.

Description

technical field [0001] The invention relates to the technical field of welding tooling, in particular to a tooling for submerged arc welding and arc extinguishing. Background technique [0002] Submerged arc welding (including submerged arc surfacing and electroslag surfacing, etc.) is a method in which the arc burns under the flux layer for welding. Its inherent advantages such as stable welding quality, high welding productivity, no arc light and little smoke make it the main welding method in the manufacture of important steel structures such as pressure vessels, pipe section manufacturing, and box-shaped beams and columns. [0003] Due to the submerged arc automatic welding, its advantages such as high welding efficiency and beautiful appearance have been widely used in the steel structure manufacturing process. But it also has the limitations of the process, that is, the line energy is relatively large compared with other processes, so it is easy to produce defects whe...
