The weld zone of thin 13 Cr stainless steel plates (2.3∿4mm) with an ordinary amount of C content, i.e., about 0.12% has been tested for the effect of heat treatment with the following results : 1) In the welding of 13 Cr stainless steel with electrode of similar type, a substantial improvement on the ductility of weld zone can be obtained by post heating at about 700℃ for an extremely short duration after full development of Ar" transformation. If, in this case, post heating is done at about 700℃ before Ar" transformation point is reached, then there will be hardly any appreciable effect of this brief heat treatment. 2) Even in the case of welding with Austenite electrodes, the above described procedure will be effective, except that unstable Austenite electrodes which are liable to produce bead cracks in longitudinal bead bendiag test without heat treatment are less effective than stable ones. 3) It seems difficult to obtain sufficient ductility of weld zone through pre-heating alone.
