    Wheel welding question

    I would never do wheels unless the tire was off the wheel but haven't run into this before. Man working on my 2 mile long driveway broke a wheel off a Cat skid loader. Half the studs broke and half pulled through the wheel. He has a weldor/mechanic coming out that is supposed to put new studs in and is going to weld in the pulled through holes. I told him it was extremely dangerous but he said the tires are foam filled. What do you guys think? Dangerous or OK?

    Just have him stand beside you and ask question.
    I would never weld with tire on.
    One mistake and you a hear loud bang if lucky and the hospital will good pain pills.
    Then start counting on fingers and toes see make it to 20.

    Welding in the center of the wheel with foam filled tires shouldn't be a problem. Still I would monitor the heat input. With the foam in there pressure build up shouldn't be an issue

    Re: Wheel welding question

    This came up several years ago. Several videos. As I recall it was not heat build up from the source. It was the heat causing a chemical reaction in the rubber and producing more heat and pressure. The reaction could continue for several hours after the heat source was removed. Thus explosion could be well delayed after repair

    That's the way I remember it?

    I remember that too. I agree working cautiously on the center might be ok.

    That makes three of us who remember those videos....I wouldn't be standing anywhere near that operation when he welds, foam or not.

    If does welding I hopping for video of the chemical reaction.
    PS I hope he does try this one and he watch a video on internet .
    I listened to old welders and never try this one.
    I can still count to 20 on my hands and toes.

    Yeah... But what's in that foam? and more than likely only a 16" wheel, not much room to dissipate much heat.

    Re: Wheel welding question

    It's a reaction that happens due to the rubber being heated.

    Bridgestone video about heating rims:



    Strongly advise against it and stand back.

    He's filling in some oblong wheel stud holes, how much heat can you put in it before it blows out? I would think about the same as if you cut off a lug nut. If I was doing that repair I would use a carbon rod centered in the hole and weld around it. A wet rag placed on the rim side would suck up any heat radiating towards the rim.

    Very true M J D, but I have learned to always assume the worst from people.

    Give people a chance, they'll surprise you in miraculous and ingenious ways lol

    I hear that. If you keep your expectations low enough you won't be disappointed.

    Supposed to fix it next week, I don't plan on being close by. I'll let you know if ambulance is called.
