Removing a Broken Stud for MIG Welding

Video Transcript

"Hi I'm Mike Rogers and on the uses of a mig welder. One little trick that I like to show you today is when you are in a position where a stud or a bolt has accidentally sheer off inside a engine block or any other metal component the mig weld could be a useful tool to remove the shield item. What I have done I have prepared this it is a piece of bolt simply sewing off on a nut. To show you how to do it. Now what we are going to do is if you imagine you have been trying undo this and it has broken the bolt off leaving the piece inside the threaded metal. How do we get that out to put a new bolt in? Let me show you. We are going to use a old nut and quiet simply lay this nut over the shield bolt and put the weld through the nut to put the two together. This has two effects firstly it joins the nut to the thread piece of bolt to give us something to get a hold of to unscrew it and secondly the heat of the welding would help to release that seized part of the thread from there. Okay lets try again. Ready, cover your eyes. As you could see it got the whole thing nice and cherry red so lets try a splatter on the nut. There we have a piece of broken bolt or stud safely removed and the threaded area ready for use again."
