Until the end of the 19th century, the only welding process was forge welding, which blacksmiths had used for millennia to join iron and steel by heating and hammering. Arc welding and oxy-fuel welding were among the first processes to develop late in the century, and electric resistance welding followed soon after. Welding technology advanced ...

GTAW weld area. Manual gas tungsten arc welding is a relatively difficult welding method, due to the coordination required by the welder. Similar to torch welding, GTAW normally requires two hands, since most applications require that the welder manually feed a filler metal into the weld area with one hand while manipulating the welding torch in the other.
Oxygas welding station (keep cylinders and hoses away from the flame) Gas welding/cutting goggles and safety helmet. Oxyacetylene welding/cutting is generally considered not to be difficult, but there are a good number of subtle safety points that should be learned such as: More than 1/7 the capacity of the cylinder should not be used per hour.
