I have taken this test several times. If you can give a little more info, we can help you alot. I would strongly suggest if they let you, run a hot pass with the 6010. Then I would grind out at least the sides as the wagon tracks you leave might not burn out completly with the 7018 and could lead to perosity. If you run it hot enough, you will not have any high spots. Are you running plate, pipe, what postitions, what is the thickness? All of these are variables that can and do affect how you set up your coupons. Please give us more to work with, and we will gladly see if we can help you.
