Razor blades

admin

As they say practice makes perfect...Here are some photos of razor blades welded together.  How do these look?  Tips, thoughts, advice?Front sideBack side
Reply:I'm no pro, but it looks like you have a consistent stack of dime which gets a little funky at the end but you have good penetration through the metal. Did you try to bend the blades and see if they popped at the weld? I am assuming you did this with TIG. I like your target test material, thats pretty good thinking there.
Reply:I would have never thought of that as test material. Nice/cheap choice.
Reply:It looks pretty good to me, but I'm no expert at tig I just started learning it not to long ago, I'm picking it up pretty good but still have a lot to learn. I have wanted to try welding razor blades for awhile or coke cans but I don't have my own tig yet I'm looking in to getting a hard rig for my sa200.Lincoln 225 RangerSa200            01 dodge  3500 welding rig
Reply:A mate of mine is doing a welding course and the instructor told him that the 'stack of dimes' look is nothing to aspire to and is frowned upon by manufacturers.He said instead that a nice smooth fluid weld is desirable from an appearance perspective.I myself have absolutely no idea but I have to take what he said as gospel, the instructor is pretty experienced.

Reply:Thanks Llundberg.I think my stack is a bit too loose "CCCCC" is not as strong as "((((((((".  Next time around I will try to stack a bit tighter.-MarkLast edited by febikes; 09-16-2011 at 01:17 PM.Reason: clean up
Reply:You way want to try a smaller diameter filler to get that effect.  Smaller wire makes smaller drops, and smaller "dimes".  For something like this, it's usually recommended to use MIG wire as TIG filler.
Reply:Nice, now try on these Semper FiJesus may have been a Carpenter, but his dad was a Millwright" A grinder and a can of paint, will make a welder what he aint' "I've done so much, with so little, for so long, that now I can do anything with nothing!
Reply:Hey febikes,There's nothing wrong with that sample, aesthetics put aside, & that indicates you are putting your efforts into learning heat control & filler insertion. The even, "stack" spacing will come in time. You seem to have good control of tung. stickout, distance to work, gas flow, & movement...... keep practicing. I'd give you an "A" on that one as most beginners can't do that on 1/8"-1/4" sample pieces.DennyComplete Welding/Machine/Fab.

Reply:just a note...too much heat and filler.The warpring is indicative of the heat. I welded 25 or so sets to hand out with business cards. I didn't use any pulse and started in the middle and welded out both directions. It kept the blades absolutely flat with no sign of warpage. Give it a whirl and see what ya think. Also if you can get some 308L filler in .035 or .030 it will help as it flows better than 70S filler and the smaller filler rod requires less heat
Reply:Thanks, I was using 70S in .035 rod.I will be doing some more since it seems like good practice and I have a big box of blades.Last edited by febikes; 09-16-2011 at 10:22 PM.Reason: add rod alloy
Reply:Razor blades no filler..http://weldingweb.com/vbb/showthread.php...ighlight=razorTry that.....zap!I am not completely insane..Some parts are missing Professional Driver on a closed course....Do not attempt.Just because I'm a  dumbass don't mean that you can be too.So DON'T try any of this **** l do at home.
Reply:I've welded them that way in the past but I still think that fusing them along the edge is harder to do especially if you're trying to keep the weld as tiny as possible.This is one I did using 5 amps, no pulse on my Kemppi inverter. The camera is just a point and shoot Panasonic and the macro isn't the best unfortunately.Note how tiny the bead is in comparison to the bevel on the razor.I find my eyesight to be the limiting factor as even with my reading glasses it's still a bit of guess work if it's fusing properly.Regards Andrew.
Reply:The real test is to weld a bead along the razor edge and add filler. Imagine they wanted to re-sharpen the blade back to original. Also the utility blades are a lot thicker than the other kind.
Reply:Originally Posted by rlitmanAnd the instructor is correct, BUT he's talking about GMAW, and this weld is GTAW. You're comparing apples and bananas.
Reply:I used SI bronze on a couple of blades (end to end).  The SI bronze filler is really brazing rather then welding and is much easier to do without warping the part.  But not nearly as strong as actual welding.The blades were almost flat after brazing.
Reply:I took my first shot at welding some blades together today. Used my weldernator. This thing has quite a bit more finesse than I ever thought it would. Now if the user was just a little better. Blades are 0.021" thick.I had them clamped onto a large piece of aluminum backer, using it as a heatsink. I struck up the arc on the aluminum then moved over to the blades to make it a little easier to get started.This isn't a traditional welder but my settings were as follows.Max amps: Minimum setting. (I don't have an ammeter to know how many amps it really is.)Pedal: 1/2 - 2/3 Pulsing it.Tungsten: 3/32" 2% LanthanatedArgon: ~12-15CFHFiller: 0.035" ER70-S6 (All I had on hand.)Brad GeorgeCurrent Equipment:AIRCO Heliwelder IV 300Amp Model - Total Awesomeness!Old 120v Hobart Handler MIGVarious grinders, cutting tools, hammers, clamps, ect..."I'm an amateur welder with lots left to learn..."
Reply:back in my day we used to weld razor blades with 1/4" 7018 at 300 amps......... haha looks good cheif
Reply:Wow. Those razor blades must have been 2" thick. Haha. Thanks man. I'm trying to learn more and practice my TIG skills. I think I'm making progress having only the internet and myself as a teacher.
