The 4 Types of Arc Weldng..The 4 main types are SMAW, GMAW, GTAW, FCAW

Scroll Down For videos

SMAW- Shielded Metal Arc welding aka Stick welding

GMAW - Gas Metal Arc welding aka MIG welding (GMAW-S is short circuit MIG, GMAW-P is pulse spray, GMAW-ST is spray transfer)

GTAW - Gas tungsten Arc Welding aka TIG Welding

FCAW - Flux Cored Arc Welding- both gas shielded FCAW-G and self shielded FCAW-S

these are the 4 main types of arc welding but there are also a few more like :

PAW - Plasma Arc Welding

SAW- Submerged Arc Welding

Shielded Metal Arc Welding is more commonly called "Stick welding" and even sometimes just called "Arc Welding"

Gas Metal Arc Welding has a few different variations
Short Ciruit mig GMAW-S is the most common for hobbyists and light duty fabrication

GMAW-P Pulse Spray vs GMAW-S Short Circuit MIG

FCAW-S Self Shielded Flux Core
