There are various structural welding tests involved and each one of them has their own things to be considered. They are usually 3/8 thick or 1 thick. Both these thicknesses use a thick backing strip and 1/4 gap. The 1 thick test is qualified for the unlimited thickness and 3/8 has a thickness limitation.

Not everyone can be a genius and there are some basic tests everyone has to go through. These tests are in both the situations i.e. vertical position and horizontal position. The one in the vertical position is known as 3G position and the other one in the overhead position is known as 4G position. When you are qualified for both the tests, you are eligible to perform all other welding tests like tensile test and all others. If you are lucky enough, you are all ready for the Fab shop.

Tips always work and there are some of the tips you can follow in acquiring these welding certification tests as well. The gap is usually 1/4, you need to use it. You need not close the gap recalling the fact that bevels are 22.5 degrees. It is essential that you get the gap for the insertion of the 1/8 rod in there. Secondly, you must clean the metal throughout. Both the backing strip and the plates should be cleaned properly. It might not clean everything but you must try to do it all.

Last but not the least; you must keep all the arc strikes within the bevel where they will be consumed with the weld only. These tips do matter when you are all indulged in the welding activity. If you do abide by all the tips mentioned above, there are very few chances that you will lose your determination.

There are other things which can put you in the dilemma which include some of the conventional things. Before there is an option for all these things, you must ask the supervisor beforehand as to how much grinding is allowed. What size rod is permitted on the root pass? Does the supervisor want to see the fit up? All these things matter and will matter till the end.

All your practice is shown in the final welding procedure which decides if you have passed the welder certification test or not. Give your best effort and you are all in the safe side when you are welding.

Nervousness is your biggest enemy and first of all, you need to overcome the fear of nervousness and then you are all ahead of everyone.
