beast Posted July 26, 2009 Share Posted July 26, 2009 (edited) all right this is agravating*** ******!!! i'm trying to forge weld, im getting a good heat i beleive, clean with wire brush then flux and beat and they just seperate every time what am i screwing up now Edited July 30, 2009 by mod07 Quote Link to comment Share on other sites More sharing options...
David Einhorn Posted July 26, 2009 Share Posted July 26, 2009 Get it hot enough that it disappears in the fire. Don't hit it too hard because the pieces will bounce apart instead of sticking together. Quote Link to comment Share on other sites More sharing options...
beast Posted July 26, 2009 Author Share Posted July 26, 2009 thats what im thinking im doing wrong i lift rock for a living and a light hit for me is probably a heavy hit for many Quote Link to comment Share on other sites More sharing options...
Finnr Posted July 26, 2009 Share Posted July 26, 2009 Heat, flux , bring to welding heat, TAP gently. As well as bounce a hard hit will blow the molten metal out of your joint. Finnr Quote Link to comment Share on other sites More sharing options...
David Einhorn Posted July 26, 2009 Share Posted July 26, 2009 It is a matter of getting two or more pieces of iron/steel with liquid surfaces to merge their liquid surfaces. Hitting to hard makes the pieces bounce apart. Ideally you are squeezing the liquid surfaces together. Quote Link to comment Share on other sites More sharing options...
welder19 Posted July 27, 2009 Share Posted July 27, 2009 Are you fluxing before or after you heat? The way you worded it above it sounds like your fluxing after you bring the metal out of the fire, you should put the flux on & then bring it to welding temp. welder19 Quote Link to comment Share on other sites More sharing options...
CurlyGeorge Posted July 30, 2009 Share Posted July 30, 2009 Use a very small hammer. That's what I had to do to stop hitting too hard. Like these guys said, just tap it together. It should bond. After it's welded together, then worry about finishing it up. Quote Link to comment Share on other sites More sharing options...
781 Posted July 30, 2009 Share Posted July 30, 2009 This advise is more for a gas forge fire but will work in coal also heat the piece to weld, near the end of the heat, heat up a piece of 3/16 round that has been tappeared to a point. When both are the same color and still in the fire touch the 3/16 to the other piece. If at the right heat you should feel them try to stick to each other. If it does not stick in the fire it will not stick on the anvil. A friend told me the old guy who taught him said to bring you mteals to heat, turn off the blower, go to the door to see if any customers are comong in the door and then go back and make the weld. This was telling him to let the steel get an even heat. Other demonstrators I watched said welding used to be so easy before everyone told him how hard it was and Bob Patrick said welding was like Olympic skating you cand do it once a month and expect to win. Soo keep trying once you get it figured out and keep practicing welding will be no problem GOOD LUCK Quote Link to comment Share on other sites More sharing options...
Nakedanvil - Grant Sarver Posted July 30, 2009 Share Posted July 30, 2009 (edited) Seeing as how one of our missions is to eliminate misconceptions, I feel I have to say something about the "liquid surfaces" idea. When we're welding, the liquid we see on the surface is either scale, flux or a combination. Think about a billet or "faggot" weld. How could those inner surfaces be liquid without the whole thing turning to liquid? And many have seen people weld at far less than what we would consider "welding heat". If the surfaces were liquid, why would you have to hammer on them? In technical circles it's known as "solid-state welding" to distinguish it from "fusion welding". "Fusion" means turning to liquid although we often use it to mean join. I do agree that the best thing is practice, practice, practice. I differ with the Olympic skater analogy, I think it's more like riding a bike, seems impossible until you do it and then you never forget how - but you still fall down now and then.
