Analysis of different welding speeds and the micro structure on the welded joints of silicon steel pipe

Abstract

Abstract This research “the analysis of different welding speeds, the micro structure on the welded joints of silicon steel pipe” has been carried out on precise and accurate measurements of parameters. The effects of different laser powers on the weld material have critically been studied and analyzed. Welding speeds have great effect on the micro-structure and morphology of the weld material. The determination of the basic components of the active agent is the key of the preparation. The active materials selected in this experiment are the commonly used oxides (SiO2, TiO2, and Cr2O3) and fluoride (NaF) reagents. However, the comprehensive experiment contains a large number of the level of combination; the workload is huge, due to the experimental site, experimental materials, funding, and time constraints lead to low efficiency. In the laser welding of silicon steel sheet, coating active agent can increase the penetration depth and affect the weld formation, and the influence of active agent NaF and SiO2 on weld penetration of silicon steel sheet is significant. The formula G is the most effective in increasing the penetration depth, including 25% SiO2, 25% TiO2, 12.5%Cr2O3 and 37.5% NaF.
