    How to talk to someone when looking for a job

    I imagine some of you have seen my other posts and know my situation, but short of it is that I am looking for a job. I am in the aerospace/mechanical field with management experience. I would like to get in for interviews with the local divisions of some of the big companies (Raytheon...

I have a big project, major part of which are 2 weldments, one steel (primarily galvanized), one aluminum. All welding to be done to AWS D17.1, non-flight...

    I am program manager on on rather large ($23 million) program that is just getting off the ground. We are building first article right now, getting a little bit behind schedule. There are a number of reasons for that, some ours, some out of our control. My customer is overseeing many other...

    I have found a problem in our shop that we haven't been able to get around. We have some parts, 7050 aluminum, with 2 legs, 8 inches long, 3/4 inch thick, 2 inches tall, 1.5 inch separation. We are using a tooling tab in the middle, bench it out after machining. The cutting is taking place in...

    F111 parts

    Here's a fun little project. I work at an aerospace machine and engineering company. One of our new jobs is to build a replacement part for an F111. The kicker is that there is no documentation that we can find, we are thinking we will have to reverse engineer the part, do drawings, and build...

    Weld all around

    I am working in Unigraphics NX, trying to add weld symbols to a drawing. I think I have it all figured out, except I can not figure out how to add the all around symbol. There is an option to put the field weld symbol, but not the all around, which goes in the same place. Can anybody help?

    Push or pull puddle

    Here is an interesting question. I was having a discussion with my welder, we were talking about pushing vs pulling a weld puddle. We were talking in reference to TIG, but I am interested in MIG as well. What is everyone's thoughts and/or experience? What difference is there in penetration...

    Allowable weld symbol?

    I have a quick and probably simple question, but I haven't found in AWS2.4 where this is specifically addressed. I have a build to print project with first article requirements. One weld symbol shows a stitch weld, 20mm on 100mm spacing, all around. My first impression was, you can't do...

    Metric material tolerance

    I am looking for some help with metric tolerance allowable on some aluminum and steel. As an example, I need 1.5 mm sheet (.059 inch) and have been offered .061/.062 sheet. My gut feeling is that this is acceptable, per the rules of the contract on this program, if it is within tolerance I can...

    Large sheet metal roll?

    As part of my project I have a large (16.2 foot length) sheet metal (t=2.5 mm) tube I need rolled to an 895 mm diameter. Surely there is capability out there to do this (it is currently being done overseas) in the United States, but I have drawn a blank everywhere I have looked. There are...

    A283 status

    I recently talked to someone who said that A283 grade C steel is no longer available, it has been replaced by ASTM 1011. Is this true? How is it worded, that ASTM 1011 is equivalent to A283C? Or similar? Thanks for any info.
