Yup, its another "critique my weld" thread

admin

Allright...finally figured Id give some Flux Core wire a try.Ive got to be honest, I like it. I didnt get nearly the spatter I thought Id get. I got much better penetration compared to solid wire welding in the same material.It took a couple passes to realize while watching the weld puddle what I was seeing was the slag on top of the puddle. After a few passes I realized I needed to go wider on my weld then the puddle was showing me. If that makes sense. Also needed to go much slower while running the bead.Im hooked. No gas. Just plug in and go.Using a Lincoln 175 with NP-211 innershield wire in .035. Heat set on E and wire speed between 3 and 3.5. Material is 1/4" angle and heavy 4" C channel. I didnt prep anything. No removal of scale. No removal of rust. Basically just stuck them together. ( I usually do clean up my metal, but since these are just practice runs, I wasnt worried.)Let the flaming begin. Id really like to strictly use Flux Core from here on out. Except on smaller material. Attached Images
Reply:Oh yeah...the last pic is a vertical down. I couldnt get my wire brush in the joint to clean it up.
Reply:Best example of split personality welding I've seen since thursday nights tig class!  (In the second picture.) I like the left half, the right side is uneven and looks too cold. Whatever you did on the left side, practice doing that!!Third pic is vertical down?... Try that uphill...City of L.A.

Reply:Its a good start and you have the idea.  Vertical UP is the way to go unless its thin sheet, much harder, but  once you master it...... Keep burning the wire.  I use NR-211 too.  I like it when I need self shielded.DavidReal world weldin.  When I grow up I want to be a tig weldor.

Reply:Once you get the technique of vertical up, you will have it no matter what you use.  It took me for ever.Vertical down is acceptable on thin stuff and its easier.  I weld exhaust pipes down. (With bare wire)NR-211 MP  is a multi pass multi position E71T-11 self shielding wire.  Good stuff.  You may like the .045, except welding the smaller stuff MAY be a litter harder.  Just keep burning it up.  I used some Esab -11 wire once and never used Hobart.  I should be running some 1/16 on Tuesday, I 'll take pics.Its all out of position stuff.DavidLast edited by David R; 11-11-2007 at 07:06 PM.Real world weldin.  When I grow up I want to be a tig weldor.
