Those are not usually that easy to weld, sometimes needs a preheating the heavier part or use a bushing made out of middle ground material thickness. Hardly never pretty, but nearly always functional. Last Saturday friend of mine paid a visit with his BMW that had a alloy wheel bolt stcuk. This one was special coded spline bolt....that has all the usual tricks to prevent theft of the alloys. Would not open with a 650 Nm impact gun and would cam out with breaker bar. Garage tried to open it prior and told that it would cost a lot and take few days to remove. Had to mutilate 19 AF socket with 3/4" drive, cut it on band saw and camfered in lathe. Protected the wheel and welded the socket at the face of the lock nut trough the socket 3/4" opening. I can tell that it is little tight fit to be able to manipulate the stick trough the straw. Used 1 and 1/2 2,5 mm good electrodes with bit over 100A current, because really needed enough weld bead to hold the abuse. Let it cool and asked friend to have the first try with 600 mm T-handle. Car would move, but the bolt not. I proceed to lift the handle and car lifted a little and bolt squaked open. That weld did not win any beaty contents, but relief on my friends face was great. Functional is the word. Chuck it there and treat it as a prototype. |

Matthew several things come out of your comments: A/ Excellent, you are coming over at Christmas - always good to see you ! B/ Yes I have 0.6 & 0.8 MIG but I reckon I'd burn thorough with that C/ No I can't wait 'till Christmas, you know how impatient I am :lol: |

You could try TIG brazing it Andrew, I tried it on a minor repair on a casting, and found it easier than O/A. Funny thing is with mig that I find it easier to weld thin metals with my 200 amp 3 phase mig than with the 160A Clarke single phase, smoother weld, and more stable it low amps, but I tend to join spots up ratner than continous weld if the material is realy thin.. Getting those flexy's on is not easy, I used to use them for repairs and replacements, and got the knack of migging them, but many years later someone brought one in, and I managed to completely **** it up! Luckily I had one on the shelf! Its all looking good! Phil |

It'll be fun to catch up and see your projects, agin!! B/ Yes I have 0.6 & 0.8 MIG but I reckon I'd burn thorough with that I suggested 0.6 as it is often used for car bodywork, people I know also use 0.8 for that. I remember in one of my other lives as a Comercial vehicle fitter having seen those flexible coupleings that were Mig welded, made sense!! C/ No I can't wait 'till Christmas, you know how impatient I am :lol: I'm not in the slightest bit surprised you can't wait! Looking forward to see you, cheers, Matthew --- End quote --- |
