Thanks. I have found the research papers much more valuable for sure. I used to have access to almost all research libraries when I was a full time teacher. Now as part time, not so much. Thanks
I have seen the ability to inspect referenced in project documents before. Until the welds overlap, Visual of each joint is possible. RT and offset could definitely be an issue.
I would think that if each joint is welded individually, preheat of each joint is correct. I understand thermal...
A welder must follow a WPS when taking a test for performance qualification.
The WPS used must properly cover the ranges used during the test
The ranges on the WPS used during the test have no bearing on the range of qualification for the welder.
A welder does not qualify to "use" WPS's. They...
The question here is related to a discussion I have had and observed many times over the years.
I'm not interested in what codes/specifications say or do not say, I'm interested in research that shows the results of the "Welds too close" topic that has been addressed here, on jobs, and other...
Here are my opinions/thoughts. These are by no means the truth...just thoughts.
1) Only contract requirements apply, without them, nothing can be inspected, reviewed, or verified.
2) If there were no contract requirements...then what else would the contractor do besides try to "get done".
3)...
The diameter ranges qualified based upon diameter tested are listed in table 10.9 of AWS D1.1.
Hope this helps...have a great day!

As already indicated, consult the code of construction for specific restrictions on Procedure Qualification. ASME Sec. IX by itself is a very "liberal" code to qualify a WPS with when compared to some others.
Joint Details in general are non-essential variables for procedure qualification for...
The WPS a welder uses during qualification has absolutely no bearing on the qualification range of that welder. The WPS used during testing MUST be suitable for the test. The welder performs the weld, and is qualified to perform any production weld within the range of qualification achieved...
I used a demo of some software at http://smartweldingmanager.com/ that seemed promising.
I have always just created my own Access Database application however that method doesn't lend itself to shared data over the internet. I have created applications for Pharm. and Power that were shared...
Yes, If the required elongation is provided. the specimens are acceptable. This is a previous interpretation issue and can be viewed here.

I am late on this conversation and tried to read through most of the posts so may be duplicating something already said.
I am sure all of the code requirements related to who can do what, when where and why have been addressed. One point I wanted to make is this.
There is NO NEED for the...
There are no rules of thumb as the variables change considerably per joint. Process, Joint Design, Access, backing, preheat, filler metal class, and other factor all contribute to how MUCH weld can be deposited in a period of time.
Some formulas and concepts that may be of great help can be...
There is nothing that controls the ratio. However if your concern is distortion, you can look in the AWS Welding Handbook, Volume 1, 9th edition, you will find a formula related to the question you ask. Chapter 7 is the location I think.
There are other variables to consider besides the depth...
I have recently taking some work for a testing lab as a contract employee. I have been performing visual inspections of welds and doing so for years. This however has been my first venture into IBC 2012 related inspections.
At 1st, I was just told to "go do a visual" on completed welds. Well...
As already mentioned, certification of some type is often required and in my opinion, always a good idea.
A company can develop their own "Written Practice" using the guidelines as contained in ASNT TC1 which establishes training, OJT, and certification requirements. That written practice...
