Welcome to Weld.com, I'm Bob Moffatt with Cowley College. I got to throw this out here for the young guys who are just getting started or the old guys who are just getting started.
When we start out processes here, at the college, people think I'm kind of rough on them or whatever, but I don't care what process we start out with. We need to be able to run straight lines consistently. Straight lines, same width, same height. Doesn't matter what electrode. 60-10, 60-11, 60-13, 70-14, 70-18, 70-24, it doesn't matter, okay?
And I see some people that start out and, I don't know, I give some pretty detailed instructions on how to do this, and I do some demos. I ran the first bead of this over here on the edge of the plate. The edge of the plate was straight. I now have a guide to go off of. I could have started next to this weld and the toe of the weld of this weld right here, in the middle of this joint. This is an old training coupon that we just, we're not cutting it down anymore, so that's what we save them for. Sometimes we'll cut them and we'll do fillet welds, and lap welds and stuff. So, I ran on the edge. I ran the first bead on the edge.
And now, in order to run straight lines, we want to orient the rod up here. This is a 5/32 70-18. I have it set at 160 amps and I want to orient this where I'm running, I'm going to set it down in the toe of this previous weld. I want to blend into this weld about halfway up, and I want to run a straight line. Same width, same height. If I change my travel speed and start going real slow, this bead is going to widen out. If I change my travel speed and race forward, the bead is going to narrow up a little bit. I'm not going to get the blend either. By the way, if you're looking at this on the camera and you're thinking wow, that's rough, that looks kind of stupid there, well, it probably does, 'cause it's got slag dripped over the edge, and I'll clean that up after a while. Matter of fact, I can clean it up while I'm talking to you. Boom! I'm done. Edge of that weld is kind of just barely hanging over the edge of the plate there. So, bad habits, bad habits to get into is to weld towards yourself, I think, anyway.
Later on, we will learn how to manipulate in all positions and everything, but right now, let's just concentrate on doing this, and hopefully, we'll see some slag peel out of it, too. Come on, darling, light up here. Don't be that way. Here we go. I need to explain what I'm seeing and what I'm feeling here. I have this rod leaning back probably about 40 degrees or so. I also have it pointed toward me about 10 degrees. That's how I can get that slag running behind me. The whole weld pool, and I'm barely touching the plate. I can feel the plate. Woo! There we go. Welcome to stick welding. I see what happened here. I've got a big old crack in my slag here, it just kind of fell off, so I've got an electrode that... Hmm, not good, not good, not good. Got an electrode, you need to check the flux on it. I found some here lately, I found a 60-10 the other day that had about 1/3 of the way up from the start of the rod. I'm going to leave that little dingus on there and see if I can weld over the top of it. When I re-strike this rod, I'm going to re-strike it out here, in the direction that I'm going. I want to kind of long art lift over and bring it back into the top of this pool here and take off again. Here, we're back in business. Again, I think I was just getting ready to say I'm barely dragging the rod, touching the material, barely. Last thing you want to do with one of these rods is gauge the plate. Now, here's something to pay attention to when we come out here and terminate the weld. Please, do not get into the habit of running this crater right here on the edge of the weld and blowing it up. Run the rod back in and fill that up a little bit. Please, please, do that for me. It's good craftsmanship. Not getting a slag peel, but it doesn't take that much to get this off here. Okay?
Also, what this is training you, you may not realize it yet, but this is training you to run multiple beads when you go to build up a big fillet weld. By the way, right here is our restart, where we stuck the rod. I'm good at sticking rods. Going to run one more. I said I was going to run one more bead and I'm going to run two and the reason is this plate is now getting saturated with heat. So I'm seeing a slight difference in the size of my weld pool. I'm watching the drag lines, or freeze lines, that's where the weld pool turns fro
