Hi all its been quite a while since I checked in. I noted some time ago that I had med and vision issues that really have taken me out of the welding shop. I created some TIG welding exercises to deal with a double vision issue. Ive already been to three eye doctors snd its not correctable by optical means. I tried TIG welding quite a while ago as well as mig welding but the vision just did not work imagin seeing two of things and trying to manipulate wire gun or TIG torch snd electrode. It just did not work I realy was devastated as much of my TIG was fine detail and mig was not aluminum and steel . Well I finally sat down and decided to see if I could do some kind or retraining so I started with a quad rules note book and tried using a pen or pencil to weld the lines together and create some patterns that represented TIG welding or mig welding. Ive reached to level of getting something reasonable for each . Ill try and get pictures the next time I get to be I out in the shop the doc says Im not supposed to be in . My skill is nowhere near what it was but I can at least get things stuck together with both methods. Fortunately there are grinders and saws to make repairs. Anyway I have a model project Im working on and before I spend a lot of funds on parts I have to ask a question. I have not done a lot of brazing and silver soldering for a long time I can still braze carbide to tool shanks if Im careful.But the parts in question are or will be 12l 14 leaded steel not very big not thick Id like to silver solder if possible rather than machine out of one piece the material is chosen for ease of machining. I know it does not TIG weld very good but silver solder or braze would be acceptable as its not heavily loaded parts about 5/8 thick on to .090 thick picture one half a double split shaft collar onto a .09 washer The point being is 12l 14 a suitable material or should I just go with mild steel normally Id probably tig tack parts together made from aluminum Let me know thoughtsThanksByron
Reply:Wow, you have some challenges to work through, I wish you well.Slightest bit of lead melting out of the steel alloy will ruin a silver solder joint, ask me how I know. It's possible to do if you keep the heat down and use a low melting point solder, probably high silver.
Reply:I have welded a lot with 12L14 bar stock. 12L14 needs per heat above 400°F to get good weld. I found E71T-1 w/CO2 or if you weld good with E7018 it works too. Dave
