ii)                   Will you please guide

a)      Which is the best consumables  brand to achieve Fe 2.5% max for top 3mm weld overlay?

b)      What is the min overlay height possible to achieve above requirement.?

c)       In case of monel clad restoration , generally we get the clad of 4mmthk

d)      What is the best welding parameter ?
