"Overall, I expect welding growth will keep pace with growth in the GNP.
Some specialized segments, such as aluminum, will grow faster than others,
while the continuing developments in nonmetallic materials will slow some
segments."
The feeling that growth will be in specialized areas was repeated often.
Areas that were mentioned included welding automation, GTA welding
because of the increasing need for accuracy and precision in welding new
metals; GMA welding with mixed gas shielding; sheet metal industry;
construction industry; infrastructure repair; transportation industry; marine
structures; aerospace; and automotive, especially its use of aluminum alloys.
Some feel the growth will primarily be in countries with emerging
economies, while the growth in the United States will be relatively stagnant.
Terry O'Connell, V.P. sales and marketing, Genesis Systems Group,
commented, "The U.S. welding market is flat to declining. Growth is
expected in Mexico and other developing countries. Labor shortages in the
U.S. will contribute to a steady growth in the robotic welding market." Joe
Scott, president, Devasco International, Inc., echoed the sentiment, "Less in
the U.S. with expectations of a slight decline in the economy, as well as the
continuing transition to a service/information economy. Outside the U.S.,
growth is expected as economic stability returns to troubled regions and their
need for infrastructure grows."
The perspective of some, though, is that welding will be used less in
the future. Chris Anderson, product manager, Motoman, Inc., opined, "There
will be less welding in the next decade. The number of welded products will
remain the same, but designs will be more efficient to minimize the amount
of welding."
- Which welding process (es) will see an increase in use and which will
see a decrease in use during the next decade?
There was much speculation as to which processes would see more use
in the future, but almost unanimously the process chosen for decline was
shielded metal arc welding (SMAW). A very few speculated a decline in the
use of gas metal arc (GMAW) and gas tungsten arc welding (GTAW).
A significant group felt the continuous wire processes (FCAW,
GMAW) would experience the most use. The GTAW process was the next
most mentioned. One of the reasons stated for its increase was "the need for
high-quality work on thin materials."
Don Connell, welding engineer, Detroit Edison, stated, "Any process
that can be automated will increase." Landon also had the same perspective,
"GMAW will increase along with automation." But he also speculated,
"Low-fume generating processes will increase." The concept of increased use
