ADVANCE OF THE STUDY OF CRACK PREVENTION BY THE ELECTROMAGNETIC HEAT EFFECT

The crack prevention for a conductor with a crack by the heat effect of the electromagnetic field is effective, in extending its service life and improving its security and reliability. The theoretical calculations and experimental studies show that a small welded joint can be formed at a small sphere near the tip of a crack inside, the conductor by smelting as the result of heat concentration effect. The curvature of the crack front will be increased in several orders of magnitude instantly and the stres...
