(Bad) MIG overhead fillet 3pass
Hi everyone. This is my first post here. I've been learning MIG welding for three weeks, and for about a week now I can't figure out how to make a overhead weld. It should be a fillet weld, with three passes. In a week, I was able to get the weld to look like a weld, not like drops of metal flowing down. But now every time, I can't melt together (connect?) the second and third welds. I think it's a speed issue and/or torch angle issue. I've tried correct it, but I can't figure out what exactly the problem is. My instructor is pretty stingy with explanations, simply saying that the welds aren't melted together, and getting advice from him is difficult. I'd appreciate any comments. (P.S. I know the metal isn't cleaned, but this isn't my decision, it's the school's practice.)
