    Look at the inside of the tubes to see if you have good penetration then grind away. The tube is also radius-ed, so the OP has a partially prepped weld already anyway.

    Comparing unqualified heart surgery to someone welding a garden fence at home? come on. Where did tho OP say he's welding cars and putting them on the road?
    There's a huge difference between smoothing a weld for cosmetic looks and having to grind off lumps of slag and having a weld that is full of inclusions.
    If you are happy with substandard bird shite to be called a weld, I'll leave you to it.

    Somehow a piece of slag that had not been chipped off, got flung by the grinder. I felt a lot of fragments hit my face at one stage, and some made it behind my glasses. Only a bit later did I feel that a piece was left behind in my eye. Thought it was loose and would wash out later, but it remains in there and scratching for three days now. This evening I dragged a earbud across my eye, and dragged it around behind the eyelid. So far, the scratching is gone, I think I got it.

    One of the reasons I grind off excess, is to see if the weld has filled up properly. I admit to be a crappy welder, and my welds are far from even height across the top. If I find any gap, or fine crack in the weld after grinding down, I grind it out to clean metal, and run another bead or three. Believe me, I have found welds that look half good till you grind it down, and find a slag pocket that opens up, basically leaving no "adhesion" between the surfaces. So its kind of a double check for myself as well. But I must admit, that I do sometimes let things slide a bit. On my piece I posted above, I have a small slag pit in the middle of my weld. As that is a 3 bead pass with 3.2mm at 120 amp on 10mm flat bar, I am not going to worry about a small little pit like that on the top bead. I will show you much worse MIG welds on my car from the Nissan factory.

    This has got nothing to do with your original comments - you had a go at someone for commenting about grinding a weld smooth to neaten it up - and said it affects the strength. Now you're saying smoothing a weld for cosmetic looks is ok??
    And if you don't grind off or chip out slag - how will you even know if you've managed to actually achieve a weld?
    A weld doesn't necessarily have to look good to achieve required strength - and even welds that look fantastic could have defects.

    If you can't take someone calling you on the bullsht you're spewing out then you shouldn't be mouthing-off on a forum.

    I think it was henk that said you get welders and you get grinders, or something like that. I think most of us hobbyists are more grinders than welders!

    I think welding is a cool skill. Don't know why I like it, but it is quite fun making stuff and fixing things. Everyone in my complex thinks I am a complete nutter as I love any excuse to drag out the grinders and fix things that have broken around the place. I will say that as much as I admit to being a crap amateur, I have been fixing things like our complex gates, and my welds are a lot better than the ones we have paid a "professional" money for.

    Obviously the "professional" was a gate guy, that probably found a guy outside builders that said he was a welder. One of the cool things with being an amateur, is that I don't really care if I use a lot of rods, or a bit more argon, and if i need to grind down and cut v's to join pieces then I am okay with that. The "professionals" just want to get it looking okay and get out as quickly and cheaply as possible. (I am obviously not referring to proper coded welders here that know what they are doing.)

    The biggest problem with welding in a complex is that grinding is inevitable and if you are doing tig, then you need to clean a lot before welding, and if you are like me, doing stick you also need to clean after the weld. So noise is definitely an issue! Less so if you are fixing things about the complex and if you occasionally help a neighbour with stuff you earn extra brownie points.

    I bought a decent welder, and although it is way more capable than me, I am still glad I have it. It tends to flatter me and it is also like the difference between cycling on a makro bike and a 100k+ Italian made master piece. Both will get you from A-B, but the better one, lets you enjoy the journey a lot more.

    Wow I seem to have poked you with a hot electrode.
    There is a big difference between smoothing a structurally sound weld for any reason and having to grind off lumps of slag and spatter so that another layer of slag and splatter can be applied over the top of the workpiece.
    I'm not a professional or coded welder but did take the time and trouble to do a accredited welding course many years ago. Since then like with most things I haven't stopped learning about the subject. I do realise the limitations my ability and equipment have so when it comes to the intricate or critical structural welds I make use of a professional coded welder.
    I'll now leave you in peace so my posts don't continue to give you arc-eye's.
