Tips to Help You Pass – Structural Welding Certification Tests
Even though there are some pretty big differences between structural welding and pipe welding certification tests, there are also some common denominators. Here are a few tips that apply to both pipe welding tests as well as structural plate tests.
It is never a bad idea to call the test supervisor before your test date to get all the details possible.
But what about the thousands of hobbyist welders out there who buy a 115 volt flux core mig welding machine from Lowes, Home Depot, Tractor supply or even Craiglist?.
keep all the arc strikes in the weld so that they will be covered by the weld. No welding codes allow arc strikes outside the weld.
keep grinding marks and chipping hammer marks confined to the beveled groove area . leaving chipping hammer pecks all over the place is like tattooing the word “Hack” on your forehead.
Either way, there are a few things you can do that will improve your odds:
The gap is usually 1/4″, use it. Don’t try to close the gap, remember that the bevels are only 22.5 degrees. You need that 1/4″ gap to get a 1/8″ rod in there.
Clean the metal. That means the backing strip and both plates. Get all the mill scale off. Sure the stick will burn right through and sure you will not clean everything that well in the field but this is a test.
Either chip and brush on every tie in or light right back up while things are still hot…one or the other.
Keep all arc strikes within the bevel where they will be consumed with weld.
Ask the test shop supervisor what kind of things will fail you before the welding certification test begins. For example, how much grinding is allowed? What size rod is permitted on the root pass? Does he want to see the fit-up? It goes without saying that you need to have practiced before you even showed up. If it is allowed, get a piece of scrap metal and weld a little while to shake off the rust. Not off the metal, but off of you.
