METHOD OF WELDING TIG WITH NUCLEAR FUSION WORKING

摘要

The invention overall in comparison with the conventional welding method relates to a TIG welding method for making a fusion as to have the characteristics of an excellent effect rising , ; the process of improvement to be 3 ~ 6 angle of groove weld steel plate (10) for a nuclear fusion ; ; tungsten rod (40) only vertically expression weld bead shape in the first pass of the first bead is inserted into the welding condition and so that the bottom surface of the large diameter of the ceramic bracket Grzegorz nozzle 20 which can shield sufficiently to open the upper surface of the weld groove (50) is characterized in that the process of welding such that .
