Rjmack,go get you a copy of the structual welding code aws d1.1,it says to only use a low hi welding process,,,if you wasn't welding to that code than you wouldn't need to,and don't believe that a 6010 weld would be less ductile than a 7018,less tensile strength, but not less ductile,,just looked up something along those lines in an old welding book I got,,according to it and aws A5.1 from which they got it from,the elongation standards,which is measured by a tensile test[how far it streaches before it breaks],is both 22 percent in a 2 inch area measured after section is pulled till it breaks,in other words both have to meet same standards as far as ductility.
