I've been using the "cursive E" style technique for just about everything but in what situations can you just simply pull in a straight line for flat butt/corner/lap joints? Am I doing extra work for no reason or does going in a straight line end up in a crummy weld? When I tried it on a piece of scrap it seemed like it made a narrow high crown weld but maybe I wasn't doing it right.I've also seen videos of going in a straight line but kind of pushing back into the pool with every move forward. Anyone use this method?Last edited by BrooklynBravest; 12-26-2013 at 02:14 PM.
Reply:My mig gun movement is more about what I'm welding together, it's thickness, joint type and position.In this thread, my welds are straight:http://weldingweb.com/vbb/showthread.php...ect&highlight=I also weave, make the cursive e, forward and back, etc.Dave J.Beware of false knowledge; it is more dangerous than ignorance. ~George Bernard Shaw~ Syncro 350Invertec v250-sThermal Arc 161 and 300MM210DialarcTried being normal once, didn't take....I think it was a Tuesday.
Reply:Pull ( drag) or push? I think what you are describing is more a straight stringer with no motions or oscillations vs just "pull".Pull/push vs using some sort of motion is a different question. I frequently do a demo for students where I start off doing a cursive e or circles, then 1/3rd the way thru transition to a "c" or "z" motion and then transition in the last 1/3rd to a straight stringer with no motion at all. When done you really can't tell where I changed my motion. It's not about what motion I make, it's about reading the puddle and manipulating it to get the results I want.Push vs pull is a bit different. When I drag or pull, typically it will tend to make a taller deposit then when I push using the motion and travel speed. That's because the bead tends to pile up on top of the weld that's already been laid down. When you push you tend to get a flatter weld with a bit less penetration with everything else being equal. Again I can change the way I manipulate the puddle frequently to alter the bead look so drag/push often look fairly similar.When you do circles you are spending more time in the same location as well as working on spreading out the puddle compared to just running a bead with no motions. You have to adjust your settings possibly as well as your travel speed to get similar results.Sounds like you haven't gotten to the point yet where you can read the puddle. Right now you are just doing timing patterns. You won't really start to improve until you get enough practice in and things start to click and start to make sense..No government ever voluntarily reduces itself in size.

Reply:When I mig i do a drag and push the puddle about an 1/8th back onto the weld I just made and repeat. Makes a nice dime stack but thats what im going for.when I first started years and years ago I used to do a weave while pushing but have since changed my technique mostly for appearance. Im not a pro welder just a hobbyist. But anymore I just tig havent touched a mig unless im at work and theres a small welding projec5 lime fixing a crack on a trailer we have or building a bracket to support a filter pot ....when I mig I try to replicate the mig like tig....ztfab.

Reply:@ BrooklynBravest - Push. Pull. Small "e"s. Little "c"s. and "Z"s. MIG like MIG. MIG like TIG. They all work and are, IMO, an operator preference based on what works for YOU. Have seen a few pros, in person, push a line without the small "e"s and it looked like Optimus Prime laid the beads with a laser. So. Try EVERYTHING and see what clicks for you. Actually prefer a straight line for PULL, and a little "c" line for PUSH. Read that puddle, wet and wash in the toes, and burn some!

Reply:How many CNC MIG'z have you seen that make little circle twerks ?Miley Inert Gas doesn't exist !Yeah. If you're gluing 1/4" bottoms to 1/4" wall 4 inch columns while using a 140-"ish"MIG. Dance boy dance ! You better attempt the appearance of proper penetration. You aint gonna get it but you can cheat.....just like the the trailer buider dorks !If your settings are right and your machine is capable, save the wiggling for the neighbors wife.Last edited by Burpee; 12-26-2013 at 07:38 PM.Bubble gumTooth pixDuct tapeBlack glueGBMF hammerScrew gun --bad battery (see above)

Reply:I always move everything a little bit, up & down, side to side. Maybe it's just nervous energy. 99.9% of the time with Mig I push, 100% of the time with any flux core I drag.

Reply:@ CEP - your "NR212" Red Face sample looks photoshopped. Highly consistent and precise. Ha! You, and many:many others output the work of robots. Nice work bro!"Discovery is to see what everybody else has seen, and to think what nobody else has thought" - Albert Szent-Gyorgyi

Reply:As long as it's slow enough to get a solid penetrated weld there's nothing wrong with a straight line. It's easy to go too fast with mig when not using some kind of pattern.For me it's got a lot to do with whether I'm gonna' be grinding the weld down for a smooth looking finished job. On an outside corner for example if I want to make it look like there isn't a welded joint I'd try to slow down and make the weld leave as smooth a surface as I can.MM210TA186TA95sLincoln AC/DC Tombstonegood old Smith torch setup 24v Readywelder mig w/spoolgunSB H 10 latheBridgeport mill6x12 K.O.Lee surface grinderK.O.Lee tool/cutter grinder |
