Mr.Siegbert thank you for your reply but I want to use SMAW and SAW
process as I have welders qualified in SMAW and SAW welders also I do
not have FCAW machines.
Thanking You.

It seems you need a usual welding material like E71T-1M/E71T-1

Be explicit about your question
Open-ended questions tend to be perceived as open-ended time sinks.
Those people most likely to be able to give you a useful answer are
also the busiest people.
You are more likely to get a useful response if you are explicit about
what you want respondents to do (provide pointers, send info,
whatever). This will focus their effort and implicitly put an upper
bound on the time and energy a respondent must allocate to helping
you. This is good.
To understand the world the experts live in, think of expertise as an
abundant resource and time to respond as a scarce one. The less of a
time commitment you implicitly ask for, the more likely you are to get
an answer from someone really good and really busy.
