I would like to ask this question from Salvaging Techniques topic in division Salvage of Defective Castings of Casting-Forming-Welding I

Answer 1

The correct answer is (b) False

The explanation: In electric arc wire spray process, welding process is sought for casting repair or salvaging of a certain metal, the weld-ability of the casting metal should be good enough to accomplish the salvaging process. But in the case of white cast iron, it has no weld-ability that means it cannot be salvaged by having electric arc wire spray process.
