Questions & AnswersHi I'm Mike Rogers and we are making this video for expertvillage.com on the uses of a mig welder. The next step that we are going to show you is a very useful technique creating tack welds. Why do we need tack welds? Well when you are setting up to create something were joining tip is steeled together you don't necessarily get it right the first time so the tack weld becomes very important. All we need to do is decide a way that we are going to place something to joint these two items together and we carefully measure the position and decide were it wants to be. We place on a ...clamp and we apply a tack weld. Close your eyes. Okay we have tacked our two pieces together. Now this is just a small weld we will hold it there quiet strongly so the two wont fall apart but, lets say oh dear and that is wrong I made a mistake what we could easily do is break this weld. Separate the two pieces and start again. So oh yes that is better. It should have been there. Again tack weld and we could have another look lets see oh yes that is fine that is so nicely lined up we can go ahead and weld those two items together.
