The main types of welding for metal maintenance are:
Shielded Metal Arc Welding (SMAW).
Gas Metal Arc Welding (also known as GMAW or MIG).
Gas Tungsten Arc Welding (also known as GTAW or TIG).
Flux Cored Arc Welding (FCAW).
At Mobile Welding London, our welders use Stick Welding (SMAW), which is considered to provide the most durable weld results and is suitable for welding outdoors.
