Ed, A few documents you should consider adding to your welding library are:• AWS D14.1- Specification for Welding Industrial & Mill Cranes & Other Material Handling Equipment,
• AWS D14.3- Specification for Welding Earthmoving, Construction & Agricultural Equipment -and-
• AWS D14.4- Specification for Welded Joints in Machinery & Equipment
These welding specifications are a little more applicable to the industry <
You asked which welds are required to be visually inspected and I had to snicker… There was a time in my life when on one side of my Hard Hat was printed “AWS D1.1 Sec 6.9” I would get this question, smile, point to my Hard Hat and say, “Look it up!”
AWS D1.1 keeps it simple, Clause 6.9 – Visual Inspection, “All welds shall be visually inspected…” Section 10.6 of D14.1 is similar, “All welds shall be visually examined.” That doesn’t leave a lot of “wiggle room”. A qualified inspector needs to visually inspect all welds.
As to who the qualified inspector is, I told you over the phone that a Certified Welding Inspector (CWI) isn’t required. Welding codes and standards typically accept the qualifications of a CWI but they don’t require certification. AWS D1.1 and D14.1 require inspectors to be qualified and that the bases for qualification are documented. In addition, D1.1 requires a regular eye exam.
As long as <A great document to use as a guide for developing your Weld Inspector Qualification Procedure is AWS B5.1 – Specification for the Qualification of Welding Inspectors (http://files.aws.org/certification/docs/b5.1-2003-errata.pdf). This is a free download made available by the American Welding Society at www.aws.org
As for what I had printed on the other side of my Hard Hat… “AWS D1.1 Sec 3.1, 2nd Sentence”. Look it up! But that’s a whole other column.

Don't forget D1.1 clauses 6.5.1, 6.5.2 and 6.5.3!
