Both mechanical properties and technological properties of metals are important in metal fabrication.
The most popular welding processes used in metal fabrication include: gas metal arc welding(GMAW) , flux cored arc welding (FCAW), shielded metal arc welding (SMAW), gas tungsten arc welding (GTAW), oxyacetylene welding (OAW), and torch or oxyfuel brazing (TB).
Metal fabrication involves many tools, processes, and skilled professionals.
