Investigating the Effects of Subsequent Weld Passes on Surface Residual Stresses in Steel Weldments by Magnetic Barkhausen Noise Technique
Publication: Publication Date: 1 March 2016Testing Method:
Variations of surface residual stresses with subsequent
weld passes were investigated in API 5L X70
steel plates by the magnetic barkhausen noise
(MBN) technique. The plates were welded by
applying a number of different passes under fully
clamped conditions. After each weld pass, the
MBN signal and hardness distributions on the front
and back surfaces of the plates were measured. A
specific calibration procedure and setup were used
for conversion of the MBN signals into elastic
stress values. The results were analyzed by considering
microstructure investigations and hardness
measurements, and then the results were
compared with the results of X-ray diffraction
measurements. MBN measurement after appropriate
calibration seems to be a good candidate for
rapid nondestructive monitoring of the variation of
surface residual stresses in welded components.
Moreover, it might provide critical data for
computer simulation and weld process design,
leading to a higher performance and longer life in
service by controlling the residual stress state.
