welding techniques

can anyone tell me for sure that you get more penetration pulling your weld rather than pushing? i myself prefer push just because of ease but ive always been taught that pulling gets more penetration but my instructors at wyotech keep saying that pushing give you more penetration witch im almost certain is a crock of shit.

pushing gives more peno and is taught as the only method is aust. on some flux core wires and mmaw u pull alum you definitely push otherwise you get excess mig soot from shitty sheilding.  sometime when doing out of postion tig work on alum you can pull. its not ideal but it gets the job done with a decent looking weld.

Id have to agree, from personal experience I get a deeper rooted weld by pushing, but it depends on the position. Pulling tends to make the weld sit higher.

Im a ticketed welder(both Canada and USA) and these guys are right....you get more penertation by pushing the weld....anything with slag though, you would pull....like Flux core or stick welding

personally i think its easier to push because i can see better where im moving the tip

i am a certified welder in canada and anything that is being structually welded should be pulled because you get deeper penetration. pushing your welds may also trap contaminents in your welds such as slag this is called slag inclusion mainly with smaw and fcaw ive done bend test both pulling my welds and pushing my welds with smaw, gmaw and fcaw and pulling my welding was always stronger as for the welding people do on trucks pushing your welds  is strong enough considering most people dont weld anything more than .250" and pushing your welding will penetrate just fine on such thin steel pulling is definently recommended when going to thicker steel such as .50 and thicker steal

thank you that is what i thought i just couldnt support my theory

Right off of Millers web site  "A drag or pull gun technique will give you a bit more penetration and a narrower bead. A push gun technique will give you a bit less penetration, and a wider bead." http://www.millerwelds.com/resources/tech_tips/MIG_tips/ I used to push my welds when I first started but now I pretty much pull everything. It's harder to see where your going but as long as you set up right you'll get it over time.
