Fire Welding on an Anvil
Fire Welding is the traditional method of joining iron. The pieces to be welded are
first heated in a forge. Timing is critical, when t
he work has just started sparking and
is almost white hot, it is brought to an anvil. The pieces are then fused
with light skillfull hammering, heavy blows are not needed. The joint created is inherently
more attractive than an electric weld.
A major disdvantage of fire welding is that it is difficult to fit large and heavy work in a forge. With large projects, careful thought must be given to the order of constuction. This necessary sequencing has contributed to the appearance of traditional wrought iron gates and railings. Electrical welding doesn't suffer from this limitation and has allowed the evolution of more contemporary metalwork.
