Fabriion-welding : SMAW & FCAW

Jun 18, 2014· Shielded Metal Arc Welding (SMAW) or Stick welding is a process which melts and joins metals by heating them with an arc between a coated metal electrode and the work piece. The electrode outer coating, called flux, assists in creating the arc and provides the shielding gas and slag covering to protect the weld from contamination.

FCAW-S Basics: Fast, No Gas Cylinders Required

When welding a groove or fillet out-of-position with NR-203, use a weave technique. Point the wire at the toes of the weld bead and pause slightly – to obtain good penetration and give time for the slag to rise out of the toes – then move quickly across the weld face before pausing momentarily again at the opposite toe. Dwell too long in
