抄録

From various literatures, authors are informed that pretty amount of arsenic in base metal has no seriously detrimental effects on welding, but small amount of arsenic in core steel is warned. Therefore authors intended to investigate influences of arsenic in core steel on cracking tendency and mechanical properties, especially shock value, of weld metal.<BR>In this investigation, coated electrode were used. And from the experimental results, they concluded as follows:<BR>a) If non arsenical mild steel is welded with low carbon core steel containing various arsenic, there are tendencies that hardness of the weld metal increases, whereas, shock value of the same weld metal decreases with increase of arsenic in core steel. And if fillet weld are made on condition of high restriction, cracks occur in the weld metal obtained with core steel containing 0.86% arsenic.<BR>b) If non arsenical Cr-Mo steel is welded with Cr-Mo core steel containing various arsenic content (<about 0.6% arsenic), there are tendencies that hardness of the weld metal decreases, whereas, shock value of the same weld metal increases with increase of arsenic in core steel. And no difference is recognized on weld metal crack. It is supposed that rather cracking tendency of the weld metal decreases with increase of arsenic in core steel.<BR>Accordingly, authors consider as follows on welding of mild steel. Deterioration of weld metal properties are so remarkable that when we have to use arsenical core steel in the future, it will be necessary to adopt any suitable methods to avoid such deterioration of properties.<BR>At the 2nd report, authors wish to describe on a important device Which is available for prevention such deterioration of properties.
