6010 v groove root passes
i know some people, like myself, use the standard 1/8 gap and landing with generally a 30 dg bevel. but i have found that certain 1/8 6010 rods have a heavier flux making them just a little to big to get the rod in and penetrate. so look for a 6010 with a slightly smaller flux coating, it helps to get the rod in better. my welding instructor told me that when there is barely any sparks coming out of the groove on your side, generally, it is a good sign of penetration.if anyone has anything to add please feel free, NOBODY IS A PERFECT WELDER so we all need help, including myself. thanks and God bless.
