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...
The WPS must list the applicable material to be welded on. The PQR variables used may cover a wide range variables for the WPS however those ranges listed on the WPS must coincide with the ranges to be used in production. If the WPS just lists P1Gr3, then thats all it is to be used on. A new WPS...
I attached it here. Forgot I could do that in t his forum.

Here is a powerpoint that I made regarding the subject of certification that highlights a few ideas about the subject of "certification".

This may help you some. Understand that this is my understanding and may or may not be correct.
The page can be commented on Here if there is any tremendous error that needs to be brought out.
This shows Figure 6.6 out of AWS D1.1-2000 This Case (IV) figure specifies the maximum dimensions...
If you have been in the same industry for 15 years, you can sometimes use that experience to narrow your search to organizations that may be familiar with your other skills. If your current employer has a need for a welding inspector, that is a great place to start.
As with being a "certified...
I too am a self study person for this type of subject. For other subjects , a course would be better for me. My interest in welding is more of a "hobby". So I study or read about it as an activity I enjoy.
I feel that probably all of the courses available have the ability to prepare someone to...
Yes, Almost all codes and specifications that I have dealt with "Allow" thermal cutting provided a certain amount of material is removed on side bends. The requirement to remove the thermal cut metal is referred to in D1.1 Fig 4.13, AWS B4.0 Figure 6.4, ASME Sec IX Figure QW462.22.
In actuality...
As a welder, the fast freezing characteristic is what makes the electrode most useful for open root applications. This allows for variations in fitup to be overcome by manipulation. I have previously qualified for open roots with 7018 and 3xx-16 electrodes. Without a remote amperage control...
I have both created my own and utilized c-specs Weld Office. Developing your own takes a considerable amount of time if you desire any type of code checking or search capabilities.
Cspecs support is great (biased opinion as I used to be part of their support staff). They will probably do an...
