Anyone whose project involves the joining
of metal knows that welding is crucial
to a smooth manufacturing process.
More than that, the professionals whose
products and services are reviewed here
think of the welded joint as the essential
link in a structure. Their welding culture
of soundness and dependability has been
evolving ever since it was discovered that
two pieces of metal can be made – in the
right hands, and with the right technique –
into a third thing of greater utility
and value.
But every point of that development
is only a way-station. As materials are
formulated for greater strength, corrosion
resistance, and other performance
factors, welding can only become more
challenging. Ever-closer monitoring of
the auxiliaries of the welding operation
– the base metal, filler metals, gases
– will be required. Welding will have
to be performed under water and in
other liquids, with no adverse effect
on the weldment. Pre- and post-weld
heat treatment and other techniques
will enhance weldability; but for broad
acceptance their costs must be brought
well down.
Welding is a mature process. But given
the greater demands made of a welded
joint all the time, very possibly the glory
days of welding lie ahead of it.
