抄録

As already described in the report 6, if the dried gases are supplied and the dried conduits are used with the rustless filler wire, a weld containing a very small content of hydrogen is obtained by the C.S. arc welding process.<BR>And it was recognized in the previous research on welding of mild steels that this precess gives the weld showing a higher ductility and strength. Accordingly, it is deduced that this process will be suitable for welding a high tensile steel.<BR>In this report, the authors clarified experimentally the composition of the filler wire, which gives the weld with the same or a more excellent mechanical properties as the base metal of a high tensile steel, Welten 55.<BR>That is, from the results of the mechanical tests of the joints and all weld metals obtained by this welding process, it was deduced that a filler wire possessing the carbon equivalent of 0.65-0.7% is necessary for a square butt welding of a high tensile steel plate, 9 mm in thickness, and one possessing a much more a carbon equivalent is necessary for the multi-pass welding of the steel plates with the thickness of 22 mm. The addition of titanium in the filler wire seems to be effective also for the increase of strength of weld metal.
