Controlling and Monitoring of Welding Parameters for Micro-Alloyed Steel Pipes Produced by High Frequency Electric Welding

Abstract

Manufacture of steel pipes micro-alloyed with Ti, V, Nb by high frequency electric resistance welding (HF-ERW) is a modern and efficient method, but requires a good knowledge and adjustment of various parameters influencing the welding process. This study aims to determine the influence of the main process parameters (electrical and mechanical) and establish correlations between them, in order to optimize the welding process. This was possible only by controlling and monitoring the welding parameters used and conducting experiments and tests on welded pipes in different conditions.
