1.	Which bead character is seen due to too high welding current?(a) Pilling of metal(b) Pilling of weld metal(c) Excess splatter(d) Small bead formationThe question was asked during an internship interview.Enquiry is from Arc Welding Methods in division Welding and Related Processes of Casting-Forming-Welding II
Answer» The correct answer is (c) Excess splatter To explain I would say: On provision of too low current, there is pilling of metal SEEN. When the voltage provided is very high, beads FORMED are too high. When the speed of weld is less, pilling of weld metal takes place and when welding CURRENTS are too high, excessive splatter FORMATION occurs.
