The influence of Lanthanum, Cerium, Yttrium, Praseodymium and Neodymium on weld hotcracking susceptibility of the pure nickel electrode used for cold welding of cast iron was studied.
Increase external restraint will reduce to some degree the effect of preventing hotcracking by trailing intense cooling.
加大外部拘束会在一定程度上削弱随焊激冷防止热裂纹的效果。
