were made up of A36 steel plate with thicknesses up to 6172 in. (16.5 cm).
The long fillet welds at the web-to-flange contact faces were made using the
submerged arc process, while the box consumed in shop fabrication for this
building, while 165,000 lb (74,250 kg) of weld metal was consumed during
field erection. Weld metal consumption in shop fabrication for the U.S. Steel
Building in Pittsburgh, Pa., reached 609,000 lb (274,050 kg).
During this same period, Kaiser Steel Corp. had used the consumable
guide version of electroslag welding to deposit 24,000 welds in the Bank of
America world headquarters building in San Francisco. At the time, this
building was regarded as the tallest earthquake-proof structure ever erected
on the West Coast. In terms of welding, one of the most intensive structures
built during this period was NASA's Vertical Assembly Building on Merritt
Island, Fla. Shop-welded sections for this giant structure consumed 830,000
lb (373,500 kg) of weld metal.
For the World Trade Center, Leslie E. Robertson, a partner in charge of
the New York office of Skilling, Helle, Christiansen, Robertson, said a
computer was used to produce the drawing lists, beam schedules, column
details and all schedules for exterior wall panels. Millions of IBM cards were
then sent to every fabricator. These cards gave fabricators the width, length,
thickness and grade of steel of every plate and section in all of the columns
and panels. "In addition," he said, "the fabricators are given all of the
requirements of every weld needed to make up the columns and panels.
Many of these cards are used as equable to the production of drawings. They
are sent directly from the designer to the fabricators. Draftsmen never
become involved."
Elsewhere in New York City, Leo Plofker, a partner in one of the city's
leading design engineering firms, extensively used welding in design. Among
Plofker's achievements are the Pan-Am Building and the all-welded, 52-story
office building known as 140 Broadway. "Our decision to make extensive
use of welding is strictly based on economics," he said. "Welded design
results in savings in steel. Field welding can cause some problems, but they
are not too serious as long as you maintain control over the welders and you
insist that qualified personnel be employed to perform nondestructive
testing of the welds."
