Re: [MW:26618] WQT- Electrode

If thickness is less no problem using 7010 because it has got more H2 than 7018. It may be lead to HICC

LPG bottle are welding using  SAW or MAG process now a days.Both are good
processes and helps to get higher productivity.

MAG with 1.20 mm size ER 70S-6 filler wire along with Argon + CO2 ( 20 % )
is very popular and much in use now a days. SMAW process is a slow process
and not used of late.

7018 or 7010 Should be defined by WPS and validated by PQR.

Dear experts,

At one particular LPG bottling plant contractor proposed  WQT approval root run as E6010 and fill as E7010.  I have doubt that E7018 is suppose use for fill up only. 

Project: Pipeline. Pipe specification PSL2( API)-  Oil & Gas. Ref. standards: API 1104, ASME B 31.4/8.

Please suggest accordingly.

Thanks in Advance.
