American Welding Society Forum
I have search some past posts here but didn't find any suitable reference, hope someone can assist.
When a visual inspection report of a completed welding task is requested, what should normally be the contents in the report.
Maybe a sample format if available would help.
See AISC 360, Construction Manual, I believe Annex M. It is the Quality Control section. There are Tables describing the responsibilities for inspections before, during, and after welding.
Thanks Scott, that's actually what I meant. Hit the wrong key on the computer.
I guess I'm slow, but I was going to ask what it is that is being inspected. Maybe he is inspecting structural steel and I missed the clue.
Best regards - Al
Leave it to Al to want ALL the facts.
Am I allowed to ask the question or are the answers received what the poster was looking for?
You are most certainly allowed to ask the question and it is a very appropriate one at that, IMHO. If we already answered his question then I would presume the structural assumption on the part of myself and Scott was correct though quite a lucky guess. In which case the OP may, or may not, respond further.
We will have to wait and see since I don't have a clue.
Happy Memorial Day.
I am looking for an answer to a VT question.
No where can I find a specification that speaks to an allowable width value past the beveled edge of a groove weld.
Is there a code that calls this out specifically? If not, what are the guidelines to determine acceptability?
AWS D1.1 and D1.5 only specify weld height/face reinforcement maximum.
API I know has specifications on allowable weld width of a groove weld. I believe 1/8" wider than the groove is the maximum there.

I didn't find anything in D1.1 or ASME either.
I don't an 1104 code book but will hunt one down.
Keep in mind that API 1104 is a standard not a code. And the 1/8" limitation for bead width is an approximation not an absolute limit (also is actually worded as a 'should').
There is nothing in ASME.
A good shop practice is to include the HAZ and or soaking pre-heat distances in your inspections. Granted, HAZ cracking is immediately adjacent to the initial weld bead, so you will be looking there anyway but let's say you are working on thick material and the pre-heat procedure calls for measuring the temperature at a distance of 6" from the weld. I interpret that 6" on both sides of the weld joint as part of welding "operation", so I look for things like handling or alignment scars as well as grinding scars and arc strikes. Likewise if I happen to notice anything visual in an area I'm not specifically focusing my work in I'll at least mark it and notify my customer verbally. Once while inspecting attachment clips on a pressure vessel I noticed a thread-o-let that was was missing the threads. Both the welder and the layout guy missed it, and likely it would have not been noticed until it moved into hydro-test bay.
D1.1 Clause 3 Prequalified WPS Requirements Table 3.6 D1.1:2015
Specifies Maximum Single Pass Layer Width - that's it for D1.1.

API 1104 specifies "The face of the completed weld shall be nor more than 1/8 inch wider than the width of the original groove."
No. It says 'should', not shall.
API 1104 20th Edition
"The face of the completed weld should be approximately1/8" wider than the width of the original groove".
Notice the language does not say bead. If the original groove is an 1 1/2" the bead can then be an 1 3/4" wide.
This language was also reaffirmed in the 21st Edition. And for good reason. It says EXACTLY what they intend.
That table in D1.1 only specifies weld width in regards to Pre-Quals and WPSs. There really is nothing else in D1.1 or D1.5 that specify a maximum groove weld width over the groove opening width.
And yes, API 1104 only recommends that the weld be an 1/8" wider than the groove opening width. Which D1.1 does in a fashion (though not a specific measurement), in that the cross section cannot be larger than the weld face.
