6010 welding rod. In this case that is 60 so the maximum tensile strength of the 6011 and 6013 electrode is 60000 psi. It mostly comes down to personal choice but if you dont want to spend too much time and effort chipping off slag then perhaps the 6011 shouldnt be at the top of your list. Moreover a real welder should never be without these two rods. In this video i am using lincoln 5p rods which are designed for open butt root pass welds.
More of a drag rod the 7018 is also referred to as a low hydrogen or low high rod in the field. Penetration is the distance below the surface that metal is fused together from the heat created from the electrical arc between the electrode and the base metal. For example welding horizontally a 3175mm diameter rod requires 90 to 140 amps while welding 316 47625mm diameter rod would require 160 to 195 amps. So that is why some welding schools are starting off padding beads using 6010 rods instead of 6013.
60106011 rods ive always used for root passes usually on pipe. A 316 electrode for example would require 160 to 180 amps on vertical welding position and 140 to 180 amps when in overhead welding position. They are ideal for use if you intend to achieve full penetration and they should be your primary choice if you want full penetration through the gauge metal. The flux contains almost no hydrogen and the rod produces smooth strong welds that are very ductile.
A plain jain 6010 or even a 6011 rod would. Im going go to give my answer and then i copied and pasted an excellent in depth answer if you want to know more. These two rods easily strike and leave very few slags. The 7018 is the backbone of structural welding.
Experts in welding generally agree that both the 6010 and the 6011 are really good electrodes. This welding rod does produce a small amount of slag but its slightly more difficult to remove than slag from other welding rods including the 6010. Moreover the welding position also dictates another increase in amperage. 6010 open butt pipe welding is definitely one path to a high paying welding job.
