The SAW (submerged arc welding) process uses a continuously fed consumable electrode (or electrodes) in the form of a wire or strip (for weld overlays)…
FCAW (flux cored arc welding) is a variation of the GMAW process which uses flux-cored wire instead of solid bare wire. Among other things, the…
GMAW (gas metal arc welding), commonly referred to as “MIG” welding, utilizes an automatically fed consumable electrode in the form of wire from a spool…
GTAW (gas tungsten arc welding), commonly referred to as “TIG” welding, utilizes a nonconsumable tungsten electrode and separate filler metal in the form of wire…
SMAW (shielded metal arc welding), commonly referred to as “stick” welding, is strictly a manual process that uses a consumable flux-coated metal electrode to provide…
Note PWHT is a very important factor that can have a significant effect on the integrity and reliability of the vessel. Omitted or improperly performed…
Attaching a support skirt to a pressure vessel does not involve a pressure containing weld. Nevertheless, the skirt attachment weld must be made properly to…
ASME Code, Section VIII, Division 1, has recently changed the requirements for NDE to permit spot RT of girth welds (Category B welds) when full…
