Abstract

This paper presents the results of Non-Destructive Testing on Magnetically Impelled Arc Butt (MIAB) welded mild steel tubes of 27mm OD and 1.5mm thickness. The tests covered as part of this work are Radiography, liquid penetrant, and magnetic particle test.  The testing results indicate that porosity, penetration levels and the defects found are within acceptable limits as per the standard. Parameters selection for this experimental work was based on trial and error adopted in preliminary trials. The irregularities found in the non-destructive testing samples have enabled the fine tuning of process parameters. The optimum values of hydraulic pressure, weld time and the weld current are assessed to be 30-35bar, 5.5s and 150A, 270 A respectively for this dimension of tubes. This work reports the experimental observations of MIAB welding and Non-destructive testing results for MS tubes of the selected dimension, which have not been reported in the existing literature. The data generated forms the data base for parametric study of this process. The optimum parametric ranges obtained from the results can be extrapolated to be used for the joining of tubes of different dimensions and can also form the inputs for arriving at parameter and response dependency equations.
