SUBMERGED ARC WELDING(SAW) The weld arc is shielded by a granular flux which acts as a thermal insulator,promoting deep penetration of heat into the w/p. Then flux is fed into the weld zone by gravity flow through a nozzle. It is used to weld carbon,alloy steel and stainless steel sheet or plate.People also askWhat is flux cored arc welding?What is flux cored arc welding?Flux cored arc welding is typically used when there is a lot of welding to do and it is out doors.FCAW is used in industrial shutdowns for welding of boilers and pretty much any industrial construction projects that need high quality welds fast.How to Pass the AWS D1.1 FCAW 3G (Vertical Up) Welding Repair and Maintenance Welding HandbookPlate Steel Low Tool Chromium Chromium Stainless Manganese thick- alloy steel steel steel steel steel ness C eq <0.3 C eq 0.30.6 C eq 0.60.8 512% Cr >12% Cr 18/8 Cr/Ni 14%Mn mm < 180 HB 200300 HB 300400 HB 300500 HB 200300 HB ~200 HB 250500 HB °C °C °C °C °C °C °C Lowalloy 20 100 150 150 100
