Hi,
been experimenting with different rods 6011 and 7014 at diffrent diam. on some heavy gauge mild steel.
I've read up on the basic concept and penetration of each rod in the manual of the welding machine , and I am aware that the 60 11 has deep penetration and more spatter, while the 7014 has medium penetration, less spatter. I ruled out 6013 because it is listed as low penetration.
My question:
1; 6011 has a nice deep arc and can see molten puddle clearly, how ever when the weld cools off there is very little slag remains on the top of the weld , where did all the flux go ? the weld looks clean, not porus, so I don't think it is infused.2; 7014 great looking weld very uniform, how ever during the weld I can't see the molten puddle because of flux float on the top, once it cools , huge tall slag on top, it chips off very easily, nearly falls off by it self, nice clean bead.
please tell me why one rod would be better than the other, for mild steel.
i would rarely use my stick welder , but when I do Ilike to use the right rod with it.
so many rods , so many questions.
