Dan_the_DJ Posted June 16, 2021 Share Posted June 16, 2021 Hello everyone, After reading for quite a while and learning that better preparedness is key, Im going to try forge welding for a second time very soon. Now armed with coal instead of charcoal, which makes managing heat higher and for longer easier, for me, I think Ill have better success than last time... I have just one question regarding the whole thing: Lets say I succeed to forge weld a 1075 bit to mild steel axe body, but what then? As far as I understand, the grain will be very large and otherwise unsuitable for an edge, so should I just do regular normalizing cycles and proceed with HT as usual or are there some more steps in between Im not aware of? Sorry if this is a stupid question to ask, but I couldnt find any information regarding my particular concern. Im just trying to better understand the process and maximize my chances of success. Thank you all for you help, cheers. Quote Link to comment Share on other sites More sharing options...
Goods Posted June 16, 2021 Share Posted June 16, 2021 The grain growth that you get in forge welding an axe bit in is not typically a problem. In most cases after welding the bit in you will still be forging out the final shape you are distorting the grain again. If my understanding is correct, grain growth is mainly a problem when you are heating/over heating areas that won’t go through more forging.

Dan_the_DJ Posted June 16, 2021 Author Share Posted June 16, 2021 So basically, forge weld successfully > forge some more and grind to final shape > normalize and HT as you would any other axe ? Quote Link to comment Share on other sites More sharing options...
JHCC Posted June 16, 2021 Share Posted June 16, 2021 Normalizing is a kind of heat treatment, but yes, that's basically it. It's the "successfully" that can be the tricky part! Quote Link to comment Share on other sites More sharing options...
anvil Posted June 16, 2021 Share Posted June 16, 2021 Actually normalizing is one of the steps in heat treating. Check out this for some help: "heat treaters guide companion". It is a free APK on Android and I believe ipod as well. It will give you the specs on how to heat treat nearly any steel you may come upon.the basic steps are Forge, normalize, anneal, cold work, harden, temper, final cold work.

ThomasPowers Posted June 16, 2021 Share Posted June 16, 2021 Just remember that not all alloys use all the steps! (You don't normalize S1 for instance---according to my ASM handbook). Quote Link to comment Share on other sites More sharing options...
Dan_the_DJ Posted June 17, 2021 Author Share Posted June 17, 2021 I only have 1075, so nothing fancy there... I was only curious what would happen to it after welding temps Thanks yall. Quote Link to comment Share on other sites More sharing options...
