Here is a pic of my first work that I've done. I figured I would post up some pics of my progress in the class. To give you an idea how new I am to this, we were practicing lighting and adjusting the torches yesterday... Anyways on with the pic of Day 1.

Details: Oxy/Ace - no filler, just practicing pushing puddles, # 2 tip, 1/8th inch mild steel. I started at the top, did ok, then got worse. lol I think i started to do circles, but now i know you should only do C's Anyways feel free to comment or give advice.

 

thats pretty cool. i welded for a while in my autobody class but haven't done to much with it. Just a little bit of exhaust work. I started the same way and you will get good pretty quick. good work so far.

 

Good job taking a class...It's nice to have an instructor that can stand there and watch you weld and give you feedback right away.

 

i'm surprised they didn't give you any filler to use. You'll like it a lot more with filler.. The silicone in the filler will help clean the metal and it won't crack.. Have fun with it

 

Your work piece probably got pretty hot which is why the bottom got worse, as u said.

 

we didn't use filler on the first day cause the teacher wanted us to get used to melting the metal. We
are practicing filler in the next class. I think it got too hot cause I might not have had the torch at enough of an angle. Cause I dipped it in water after each pass.

 

actually looks better than my first day with oxy welding. your instructor has a good idea with having your class just practice melting the metal and pushing the puddle, adding the filler to the equation right away can be overwhelming for some students.

dipping mild steel in water while still extremely hot speeds the cooling process and causes a crystalline structure in the metal called martensite (sp?) to form, which is not what you want if you're going for strength. on test plates like what you're doing it's fine to dip it in water, and i'm sure you'll learn a lot more about steel's crystalline structures and how heat input, preheating, and post heating affect those structures in your class.

whatever you do, don't ever dip a weld in water that you are going to have stress tested for class. put it on a concrete floor and let it cool naturally.

 

Ya we touched on that in my material tech class.. isnt it called quenching or something? The only thing im going to have to get used to is, I like to look pretty close to what im working on... so the heat given off from the metal felt like I was getting a sun tan. Tommorrow we are practicing filler, so ill post some pics of that when im finished.

Quenching is just dipping metal into the water in the quench tank.

Over time, you'll get more and more comfortable welding without getting real close. I did that too when I first learned oxy/ace welding. You want to break that habit especially if you're going to be welding in the overhead position.

Oxy/Ace welding is fun

 

Day 2

Details are the same as Day 1, no filler yet.

 

turn ur amps down 10 your way to hot from the get go i did the welding calsses all threw high school and collage and i build tanks ant refinery's but other than that its not to bad.. better then some most people ive worked with

He's using a torch.

 

oh i c then thats my bad lol.. i looked like really hot 7018 ok your doing good just try to keep it cooler and youll do fine

I'm sorry to say but if you thought this was stick welding... you are obviously not a welder...

 

like i said my bad i wasnt paying and attention to what he said he was welding with.... but like i said last time it looks good just keep thing more on the cool side

 

If it was stick welding and it was that flat, the bead would look really jagged because there would be so much heat and your travel speed would be really fast.
I think the point of using no filler is to get your speed down and to find a good distance away from the work piece. Looks good.

 

wierd, the first thing we did in class is stick weld. doing some oxy cutting tomorrow but we dont weld with it at all.
