tungsten inclusion meaning in Chinese

夹钨

Abstract : with the aids of computer ' s hardware , executive mechanism of weld arc length automatic controller of all - position pipe welder and additional software , an automatic system for arc striking has been developed , in which touch - starting method using tiny current is introduced . utilizing this method , the ablation ratio of tungsten electrode and tungsten inclusion ratio of welded seam is far smaller than normal touch - starting method . and the successful ratio of arc striking is high
