I had three 8-32 screws sheared off flush. I made a washer out of hex stock with a .110 hole. I countersunked one side. I then clamped it over one screw and gave it a one sec shot approximately with the mig.It came right out with a wrench. The other two came out with no problems. You can see the washer in the picture. I first tried the tig but was getting the washer to hot. Attached Images

Reply:The majority of my welding is getting out broken off bolts and studs. I originally bought my TIG machine just so I wouldn't have to bother the Fab guy across the street with my little projects.
Reply:I use my O/A about as much for removing frozen bolts and studs as I ever did for welding. On heavy sections, castings, etc., sometime propane-air and even mapp-air just won't heat fast enough around a damaged and frozen fastener to help break it free. Fast heat is essential so that the surrounding material heats and expands before heat conducts to the fastener. First time I did this was to get frozen brake bleeder screws out of brake calipers for a Pinto (Ford's answer to the Molotov Cocktail). Brake fluid gets nasty and causes corrosion. With O/A, the screws came out squealing all the way, but they came out. Wished I could have found the idiot Ford engineer that failed to spec anti-seize compound in final assembly. |
