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...
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...
Are there any restrictions for welding a flush patch in a NEW API 650 tank provided 100% RT is performed. (Additional Reinforcement, Lowest course, etc.)

We have a piece of equipment we are workin on that we are trying to add a brake to. I have a clutch that will engage at 350 RPM however the driving mechanisim will only rotating at around 48 rpm. I was going to use sprockets and chain but am wondering if this is the best method.
From what I...
I have used quickcad (autodesk) for a few years and recently went to turbocad since our compnay wanted some 3d representations of what we build. Both of these products experience errors when using the database functions. The higher costing turbocad V10.2 is actually MUCH less stable then the...
I am working for a small company that custom builds floating boat docks. I am not an engineer and am looking for some guidelines on concrete reinforcing. The practice in the past has been based on "it looks strong enough" type engineering.
Could someone lead me to some recommended practices...
My employer has some cad files a prior employee made with ACAD 2000. He had been instructed to draw some isometric sketches in 2d but made them as actual 3d files. He and the program he had are gone.
We have Autodesk Quickcad and when the files are opened the z-plane is flattened but does not...
Is there a way to browse to a folder using access/vba and store that path in a field. I can currently get the filename fine but was wondering if the same can be done with a folder.
I have stripped the filename off the complete file path but that requires the user to select a file within a...
I have a database I am working on for tracking orbital welds and would like to know if all of the requirements for what data is required to be tracked is contained in the ASME spec or does it change greatly between customers and projects.
What I track now is Welder, Machine, Program, Head...
I have been working on an access dataabse for tracking orbital welds and am wondering if there are any commercially availablle programs already out there.

Are there any manufacturers recomendations for flame straightenening 2205orsimilar material. I am interested in maximum temp and optimum cooling rate.
I have seen this being performed at a shop I am doing some other work in and I am looking for some information to give them to develop a...
I am observing welding on a Duplex Alloy 2507 Heat Exchanger and observed isolated oxidation (sugaring) on the internal surface of whe root pass. This entire weld is going to be ground flush however should the areas with severe oxidation should have the weld metal background to remove some of...
Are there any codes or standards related to the inspection or design of metal bellows expansion joints for ductwork or any case histories of in service failures and their causes.

I have a friend that builds boat dock and wants to know how much a 40' 4" x 6" x .120" Wall would sag over a 40' length under its own weight. These are used to attacc a recreational boat dock to the shore. If there is a formula I could use that I could understand I would use it...
I have question about failure of welds and surrounding pipe.
If
1) a weld failed in a brittle fracture mode and
2) the piping was above the minimum design metal temp and
3) the piping was verified to meet the original mechanical specification
Would the surrounding un welded pipe many feet...
I have come across a joint with an approved design for its application but I would like to learn more about my doubts.
The joint is a mitered joint between two pieces of structural tubing. Instead of butt welding the ends together a 1/4" filler plate is placed between the two ends and a...
