AI Technical Summary

Problems solved by technology

The current commercially available electrodes have excellent performance and excellent impact and wear resistance, which will greatly prolong the service life of workpieces subjected to strong impact and wear. However, in the production process of surfacing electrodes, the drying process is relatively backward, and the drying time Long, and the coating of the electrode after drying is easy to crack, resulting in an increase in the scrap rate

Abstract

The invention discloses a preparation method of a surfacing welding electrode, which comprises the following steps: (1) put the welding core into the soaking liquid and soak it for 50-70 minutes, and then take it out; (2) add sodium chlorite, hexa Sodium fluorophosphate, after mixing uniformly, the binder is prepared; (3) After the coating and the binder prepared in step (2) are mixed uniformly according to the mass ratio of 10-15:1, press-coat to On the welding core, dry the welding core in an oven at 110‑120 ° C for 1 hour to obtain a surfacing electrode. The preparation method of the overlay welding electrode provided by the invention, the prepared electrode has excellent stability of the welding arc, is easy to remove slag, and has almost no splash phenomenon, and the prepared overlay welding layer has strong impact resistance and wear resistance, especially In the preparation method provided by the invention, the drying step takes a short time, and compared with the existing drying process which takes about 3 hours, it saves about 2 hours, and the drying temperature is lower, which reduces energy consumption.

Description

technical field [0001] The invention belongs to the technical field of preparation of surfacing welding electrodes, and in particular relates to a preparation method of surfacing welding electrodes. Background technique [0002] Surfacing welding is an important branch in the field of welding. Its purpose is not to connect parts, but to obtain deposited metal with specific properties such as wear resistance, heat resistance, and corrosion resistance on the surface of parts. Therefore, it is used in metallurgy, mining, agricultural machinery, petroleum, etc. It has been widely used in the manufacture and repair of parts in chemical industry, power station, vehicle, aerospace and other industrial sectors. An important feature of surfacing welding is that it can make the base metal have good mechanical properties, such as strength and toughness, while the deposited alloy layer has excellent wear resistance, anti-adhesive wear, corrosion resistance and impact resistance. .
