Abstract
Authors surveyed the influences of three different methods (JIS, modified ISO and ISO) for the tensile test of deposited metal-in the former two, in as welded condition and in the latter, after hydrogen removing treatment, the test is carried out-upon fisheye appearances and mechanical properties of deposited metals from various types of mild steel electrodes, and further investigated some metal-lurgical properties of deposited metals.
From the experimental results, authors found that fisheye appearances revealed in ordinary strain rate at room temperature are influenced by the deoxidation degree, the diffussible hydrogen content existing in time of test, the size and number of porosities in deposited metal.
