Abstract

Covers the essential welding variables for carbon steel in the thickness range of 1/8 through 1-1/2 inch, using gas metal arc welding (short circuiting transfer mode) with argon plus 25% carbon dioxide shielding for the root followed by flux cored arc welding (globular transfer mode) with argon plus 25% carbon dioxide shielding for the balance. It also cites the base metals and operating conditions necessary to make the weldment, the filler metal specifications, and the allowable joint designs for groove welds.
