Introduction When welding procedures or welding performances (welders) are qualified, test pieces are prepared using a specific combination of parent material and consumables. To reduce the number of welding procedures to be qualified for production applications,...
Flux Core Arc Welding

Flux Core Arc Welding

Information and Guidance to FCAW Flux core arc welding (FCAW) was introduced in the 1950’s as an alternative to shielded metal arc welding (SMAW). The advantage of FCAW over SMAW is that the use of the stick electrodes used in SMAW is unnecessary. This helped FCAW to...
Shielded Metal Arc Welding

Shielded Metal Arc Welding

Shielded metal arc welding (SMAW), also known as manual metal arc welding (MMA or MMAW), or regularly as stick welding is a manual arc welding process that uses a consumable electrode covered with a flux to produce the weld. An electric current, in the form of either...
