In addition the company undertakes a significant amount of weld overlay utilizing sub-arc, strip welding and electroslag processes.

Electroslag welding is used mainly to join low carbon steel plates and/or sections that are very thick.

Between the late 1960s and late 1980s, it is estimated that in California alone over a million stiffeners were welded with the electroslag welding process.

Electroslag welding, a single pass welding process.

Electroslag welding easily lends itself to mechanization, thus reducing the requirement for skilled manual welders.

The electrode is guided into the weld area by either a consumable electrode guide tube, like the one used in electroslag welding, or a moving head.

Electroslag Welding (ESW)

Many welding processes require more than one pass for welding thick workpieces, but often a single pass is sufficient for electroslag welding.

Not one failure or one crack propagation was initiated in any of the hundreds-of-thousands of welds made on continuity plates welded with the Electroslag welding process.

Other arc welding processes include atomic hydrogen welding, electroslag welding, electrogas welding, and stud arc welding.

A major difference between EGW and its cousin electroslag welding is that the arc in EGW is not extinguished, instead remains struck throughout the welding process.

Electroslag welding (ESW) is a highly productive, single pass welding process for thick (greater than 25 mm up to about 300 mm) materials in a vertical or close to vertical position.

Two of the tallest buildings in California were welded, using the electroslag welding process - The Bank of America building in San Francisco, and the twin tower Security Pacific buildings in Los Angeles.

However the Federal Highway Administration (FHWA) monitored the new process and found that electroslag welding, because of the very large amounts of confined heat used, produced a coarse-grained and brittle weld and in 1977 banned the use of the process for many applications.
