ok so im welding 1/4 inch flates in my frame and gussts i have a lincoln 125hd runs off 110v i run .035 flux cored wire i have the voltage maxed out on E and a wire speed of almost 2 i run one bead down the seam burning the 1/4 into the thinner frame metal i grind that down and run another pass over it them just smoothe that one over so it looks good ive had people tell me my welding skills are pretty good and am taking a class right now to get cirtified my question is am i getting ample penetration with my welder to be structurly sound in my frame
Without seeing it, I can't give you a good answer. What I can say is, typically running flux core downhill is a definite no-no. It is very easy to trap flux under your weld because it can run ahead and under the molten weld puddle. So when you get done, on the surface it may look good, but you might have a bunch of flux trapped underneath with a relatively thin weld deposit on top. You might want to check one of those welds by grinding it out and seeing if it is full-thickness weld metal or if you have trapped flux.
