Metallurgy & Welding 8-2 Commentary: Many WSMF structures designed in the last 10 years incorporated ASTM A36 steel for the beams and ASTM A572 grade 50 steel for the columns. This provided an economical way to design structures for the strong column - weak beam provisions contained in the building code. Recent studies conducted
High-strength low-alloy steels include many standard and proprietary grades designed to provide specific desirable combinations of properties such as strength, toughness, formability, weld-ability, and atmospheric corrosion resistance. These steels are not consid-ered alloy steels, even though their desired properties are achieved by the
Welding is the principal method for joining steel. But even more signifi cant, welding is vital as a practical method for fabricating steel structures and pressure vessels for modern liv ing. From thi point of view, welding is as important to a fabricator as oxygen cutting, forming, and machin ing. However, welding did not gain its
Jun 26, 2007 · Pls do not overlook preheat and interpass temperature as part of the important parameters. Remembered back to about 16 years ago, I have seen and worked when was a UT man, have rejected a lot of built up box beams for offshore module during fabrication and have scrapped at least two completed built-up box beam (for support modules) due believed to be delayed cracks.
