    A lot of welds are ground and polished but this isn't the case, something is wrong here.

    Hard to tell with them ground like that. But from my experience when someone grinds a weld half way down it's because they are trying to hide an ugly bead.

    If you grind your welds you are a grinder not a weldor. That's all I have to say about that.

    about grinding welds, i always grind my welds, always, for a paying job, rarely for myself. some gravy, flat work usually can skip the grinding, but if i am building a complex frame where people will be using it, hands on, i like to clean up the welds, removing any spatter or sharpies, that does not make me a grinder, it does make me a smart business owner,if i put a finished product out the oor with some spatter on it and some one gets cut, i can get sued, this is america,

    There's a difference between removing spatter and grinding half the bead down.

    Default good or bad welds

    well I didn't see any porosity that is a plus but that is a fine example of mechanical undercut and a bit of L.O.T

    Hey Kevin
    Always clean spatter and any sharp edges that's just doing a job right. Unless specified don't grind your welds.
