JuegosStructural welding certification tests are usually either 3/8″ thick or 1″ thick. Both thicknesses use a 1/4″ thick backing strip and a 1/4″ gap.
TrabajarBut 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?.
Empleo The 1″ thick test qualifies for unlimited thickness and the 3/8″ thick welding certification plate test has a thickness limitation. Most people think the 3/8″ is a bit easier.
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.
Lets use the chopper handlebars for an example. Obviously, you cant destroy every weld you make but what if you were to weld up a mock up set of handlebars just to prove the weld settings? Wouldn’t it be worth the price of the tubing just to have confidence in the welds?.
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. you can be published without charge.
