Hey awspartb!
What are you doing in NY state? ;) ;) ;)
There is no plate test for NYSDOT which stipulates that the plate must be positioned at a 45 degree angle!!! There are two positions required for you to take in order to (hopefully if you pass) become certified, and they are the vertical and overhead positions in order to qualify in the Flat, Horizontal,Vertical and Overhead positions for both groove and fillet welds as well! There is also a thickness limitation which depends on the test plate thickness used on the test and what yuo're qualifying for as well as two classifications of welder, such as a shop or field welder (refer to the bottom of page 106 in the attached .pdf file)... Who ever is feeding you this bunk is either pulling your leg, or does NOT know what they are talking about!!! LOL :) :) :)
Here's the .pdf file which will explain everything to you:
https://www.nysdot.gov/divisions/engineering/structures/manuals/scm/repository/scm08_section8.pdfhttps://www.nysdot.gov/divisions/engineering/structures/manuals/scm/repository/scm08_section7.pdfThis last .pdf is something you should look over because it clearly spells out the type of quality in workmanship standard expected of the welder whether they be a shop welder or a field welder, and I think it should be a requirement for you to understand that this test which you will take according to what is inside the firsr .pdf file also must meets the standards written in this last .pdf file as well!!!
So, I hope this will clarify the test for you! ;)
Respectfully,
Henry
