Abstract The hydrogen distribution in metals can be measured by means of laser hydrogeh detector set up in the authors' laboratory. The results show: 1. Relative hydrogen index D_H may be used to indicate relative content of hydrogen, with consfant background hydrogen in steel 2. The hydrogen content is related to the time of hydrogen penetration and the distance between the surface and the point measured; 3. The measurement of the hydrogen distribution in various welded joints shows that such distribution varies with time. Our practice proves that the hgdrogen detector set up in our laboratory can be used to measure local hydrogen distribution in metals.
