What's the point of the triple pass? That material doesn't look thick enough to warrant that?
well i did it for practice. in my first post it said on scrap metal.

Ok, well congratulations. Looks like a nice pile of filler. ???

Yeah, me too. I have found that if I need something welded I ask someone who knows what they are doing. When I weld it ain't purdy. It kind of looks like some sneezed on the metal when I get finished with it.

Explain how you created these welds. What techniques and such.
Depends on the temperature it was brought to. If my memory is correct-quenching steel can bring it into the martensite phase which actually makes it softer. Its better to cool it faster than the air will cool it however not so fast as to put it in the wrong phase.

Yeah This guy seems like a TOOL
If you have seen his comments on pirate.

If steel is brought to ~1500*F (give or take depending on the carbon content) and quickly quenched (in oil or water) it becomes martensite. Above that temp steel changes the cubic structure which allows more of the carbon in the steel to dissolve into the iron structure. makes the steel very very hard but also very brittle. Martensite is the hardest phase of steel and also the most brittle. In order to heat treat steel, it is first turned into martensite and then heated to a certain temp. (depending on the hardness/brittleness ratio desired) and allowed to slowly cool. Since welding occurs at above 3000*F if the piece was quenched while it was still above 1300-1600*F it would have become martensite and would be very brittle (but also very hard). Generally it is a bad idea to quench after welding.

you're a tool. stop trolling for a cookie.
wanna impress someone? then show us something you built otherwise you're a tool!
UNSTUCK
But stuck more often.
I like those guys. Hope to be one some day.
Well my first pass i did a triangle pattern. burning straight into the root right above my two paused stops which created my puddles. then instantly straight back down pausing on each side making sure i have more time on the sides then the center to keep it flat. Second and third pass are just the z weave pattern. each pass I made sure my weld only went half way past the previous weld on each side. Not sure if that is a good explanation, but the best I could do.
And I only quenched the pieces of metal to make up for the size of the material. like I was taught in school. Doing a three pass weld like that without cooling on such thin material would make it way to hot by about the second pass and make the puddle hard to control. When doing this on thicker materials like it's meant to be done on i know and understand you would not quench it. bad idea.
