Ironic metallurgist, the spec additionally says that short arc GMAW might only be used for root pass.
Weldstan, you are right. The spec is a bit old (prepared in 1995 and revised in 2005).
Thanks everyone for your inputs. Still have no idea why there is 9.5 mm (3/8'') thickness limitation.
Hi guys, I've been through some welding spec for piping/pressure vessels and was curious about one requirement:
GMAW may be used for fill passes provided the transfer mode is globular or spray arc and the completed thickness is of the weld is no greater than 9.5 mm.
Does anybody know what can...
