I went from Mathcad 14 to Mathcad Prime 4.0
I am trying to move several of my work sheets from Mathcad 14 to Mathcad Prime 4.0 and am not finding where in the text field I can show a text of the variables I am using with a sub script.
I have just tried to draft the language in WORD and past it...
We have been asked to provide structural steel that is shop painted using a verity of shop coatings.
In places where the field will be placing welds we have been asked to coat the weld hold back area with a weld-able primer.
I have always been concerned that there cannot be anything in the weld...
I am on a project where the contractor has changed the requirement for bending a stud from the 30 deg that is in the D1.1 to holding us to only bend the stud to 15 deg to satisfy the Clause 7.6. We had several studs that are bend at 30 deg and are being told to bend them back to 15 deg. I am not...
I have a conflict between a CWI and myself regarding when the VT must be done on a weld that will be UT tested.
My point is that section 6.11 (this is to the D1.1:2000 because it is on a nuclear project) says that the "Welds subject to nondestructive testing shall have been found acceptable by...
I am trying to find a clause in AWS D1.1 that provides the minimum length of a fillet weld. I looked in Clause 2 and found the requirement about minimum in design space but I need the reference to that I think should be in Clause 5 that tells me that a fillet weld can only be made so long...
I am working on a job where the design engineer has called for a Flare-bevel-gorve weld with a specific effective throat (a PJP weld).
I cannot find in the D1.1 how to measure the weld once it has been placed. This project is subjected to a great deal of inspection.
These are HSS 8x8x5/8 members.
I have two separate contracts where the owner / owner’s engineer is requiring us to plug a misslocated hole. We have a repair procedure written based on information we pull from the AWS D1.1. One of the customers is now asking us for the PQR for the work done to make the repair to the base...
I have a project that requires a great deal of MT testing of the fillet welds. We have an inspector that is telling me that you have to MT before you blast clean the material. The comment is that the blasting will affect the profile of the weld. It seem logical that if the weld is blast cleaned...
I have been asked to approve the use of the age old J bolts for the crane system in our shop. I don't like the J bolts since I keep finding them on the ground in the shop.
Does any one have any references I can look at about the pros and cons of J bolts.
I have the most current CMAA doucment...
I am looking for some information about the affect of painting the bottom of a baseplate if you are counting on the contact between the steel and either grout or concrete for shear strenght. I am not going to be able to use any kind of shear key or welded washer to transfere the horzintal force...
I have been dealing with the issue of how a fillet weld should be terminated for some time. As a fabricator years and years ago I was tought that a fillet weld should be stopped a weld size back from the end of the parts being joined. In the 2005 AISC spec there is a user note that say this is...
I am trying to find something in an AWS spec that gives me more information about welding stainless to carbon steel. I know I need a 309 electrod but I need something in AWS to reference for the customer I have.
I looked in D1.6 and could not find stainless to carbon.
Any help would be great.
I have a project that requires approval of my welder qualifications. I have several welders that we qualified against the D1.5. When I submitted the qualification report to the EPC firm they rejected it because the project is a building (D1.1). My welding super tells me that the qualification...
I am doing an nuclear "NQA-1" project and need to buy some hillside washers to be used with a girt system. The hillside washers are for the sag rods.
I need to know the ASTM a hillside washer is made to so I can get the material qualified for use on the project.
Any help would be great.
In Table 1 of ASTM A6-08 there are five (5) notes. Note 4 reads "For thicnkesses measured at any location other than that specified in Note 3, the permitted variations over specified thickness shall be 1 3/4 times the amount in theis table, rounded to the nearest 0.01 in." I read this as...
