How to Grind Welds with a Handheld Grinder

Video Transcript

"On behalf of Expert Village, I'm Terry. And today I'm going to show you how to use a hand held grinder. On this piece of metal, I have a weld here. If this was not cosmetic and I wasn't going to see it I wouldn't worry about it. But let's just say this was on something I'm building and I want to finish it to where you don't even know that a weld is there. And that the material is nice and pretty and sound. So what I would do is clamp it down, so it doesn't wander off. These grinders turn about 1800 rpm. Once they get to rolling, if they flick your project around the room it?s not very fun. I'll start off with this grinder. I'm going to use a thick heavy coarse stone wheel to just take the excess weld down. I don't want to take it down so far that I start moving metal around the weld. I just want to take it down to there. And then I'll use all my other attachments to finish it off. Using your grinder, on this weld right here, I took the leading edge and just used the leading edge. Notice, I got a little here into my mail, but around here it's untouched. And that's just what I wanted, because I got some finer grit sanding and grinder wheels that will take care of that. If I'm just a big piece of steel I'm wanting to knock off excess BB's or what have you. I'll lay it flat and just let it ride itself around and go smooth. But I don't want to mess up any of this other metal. So that's why I use the leading edge like that. It eats it off a lot quicker. And that's how you do that."
