First time damascus WIP

That's the idea; welding dry surfaces. There is no oxide build up for there is no oxygen to deal with. Kerosene is not a [cleaning agent] so does not qualify as a flux. Lets put it under welding technique, along with other welding techniques. Borax is called on to cover ever square inch of the surfaces being welded. Any surface being welded must be covered with melted Borax. Using kerosene only the exterior of the billet is being shielded. Welding with kerosene shields the surfaces from scale inclusions, along with those ugly dark spots, which are the result of the flux carrying impurities onto the surfaces being welded. Whatever name is being used to describe welding with kerosene, it is cleaner and produces better welds, more consistently than welding with Borax. The only caution is the welder must show care when pulling the billet from the forge, the solid carbon shield produced by the kerosene being consumed is a bit fragile and must be handled with care.

Happy grinding, Fred

 

I’ve been trying to build up the courage to have a go at this. Your thread pushed me over the edge. I went with the weld all the seams shut method and sprayed it down with wd40 for good measure (yes I went overkill with my flux core welder, I’m still trying to learn how to do that kind of welding too). So far I’m happy it looks like I got it to stick, and my 1084 and 15n20 seems to match up with your colors on the quick etch test. Up next is drawing this thing out with me myself and I to try restacking. Thanks for posting your journey and nudging me into finally trying.

 

I find grinding a little taper on the end of the rebar so there is a little wedge between the rebar and the billet to get the weld in helps. That said, when I was really wailing on it to draw it out the weld still failed, and I had to switch to tongs part way through. The welded on rebar was good for the initial set though because there were no tongs in the way.

 

Preheat the area you're going to weld with a plumbers torch. Will help you get better penetration with an under powered welder. 400f or so. Also grind to bare metal as you don't have the power to burn through scale. Get every amp out of your welder by grinding and grounding to bare metal as well.

 

How come your weld is so nasty. I was trying to think of another word to use but that’s all I could fine up with. Welded like that will not hold as it’s just built up on gunk. I use a small 110v mig and don’t have a problem. I grind the end of the rebar at a 45° angle all the way around so it just about pointy. I tack it in place and then weld up the entire gap around the rebar. That small welder should be fine for attaching a stick to your billet. Check your setting on the welder. When welding it should be smooth. It should not be pushing the wire into the weld and putting out the arc. I would set the welder on high and adjust the wire feedtill you get a nice burn. You should be able to hold the wire just off the steel and pull the trigger and it just welds for as long as you hold the trigger. If you feal the wire pushing your hand back away from the weld then the wire is to fast. If the wire keeps burning up to the gas sheald then the wire is to slow. Here is what a good weld on a billet should look like. And this one is not even that good but it held through the entire process of the Damascus.

 

Are you sure your using flux core wire?

 

Wire speed up for penetration and you will have a real short duty cycle with it turned up all the way, so go quick and let it cool a bit (welder) for every weld. Better welds when it is not over heated. Also heaviest wire it will take if there is a flux core option.

 

I don't know what welder you have my wire feed is a harbor freight my welds looked like that until I tried the right wire (3rd try Lincoln) also I had a one hour lesson from my knife teacher. One of my local welding suppliers gives lessons by the hour it's a handy skill for a knife maker.

 

Well , it not broke ..........it fell To broke must be weld I like what are you do so far , but please find someone to teach you how to weld ...it s easy

 

What kind of welder you use ? Did you have argon or Co2 turn on ? Looks to me like you have no gas supply ?

 

Check your polarity too. Flux core and solid wire are different, the lugs are where the spool goes. Are you sure it is flux core wire/ get some good wire.

90 amps is really light, so you will only get a small bead weld. Watch youtube on welding t joints, you could be running cold and not moving the torch enough for your small amps
