Abstract

A sintering welding wire for the multi-wire high-speed autoamtic hidden arc welding contains MgO (19-28 mass%), CaF2 (12-18%), ZrO2 (8-15%), Al2O3 (18-24%), SiO2 (17-25%), CaO (7-13%), RE (0-7%), MnO (0-5%), TiO2 (0-5%), Na2O+K2O (2-5%), S (0-0.05%), and P (0-0.06%). Its advantages are stable arc, beautiful welded seam, and high welding speed (1.5-2 m/m).

Description

technical field [0001] The invention belongs to the welding technology of low-carbon micro-alloy steel materials, and mainly relates to a sintered flux for multi-wire, high-speed submerged arc automatic welding. Background technique [0002] Welding technology is an indispensable processing technology in modern industrial production. With the development of science, technology and economy, welding technology is becoming increasingly automated and high-speed. Submerged arc automatic welding is widely used in the production of large-scale welding structures such as machinery, pipelines, ships, boilers, pressure vessels, and bridge structures due to its high degree of automation, fast welding speed, and stable weld performance. With the enlargement of the product structure, the wall thickness of the welded steel plate is also increasing, and the traditional single wire welding can no longer meet the production needs. In order to improve production efficiency, multi-wire and hi...
