[MW:2813] Re: LTCS Welding

MDMT for Ammonia service is normally below -30 degree centigrade , as you are using A333GR6 Materials which are normally certified for -46Degree centigrade , you use GTAW using ER70S2 Filler wire with impact tested propoerities -46degree centigrade  and rest welding using E 7018-1

Best Regards,

Dear Friends,



I like to know whether we can use the combination of E6010 in root and E7018-1 as filler in LTCS (A333Gr6) welding, particularly in Ammonia service (flash point is minus 33 deg C)?



The working temp is less than minus 33 deg C. At what temp should I impact test it?
