Nice looking welds. :thumbs:

...try doing a butt joint and try the break the weld...

I agree. This will show you alot. Try playing with the machine, Increase/Decrease amperage, speed, wire feed. This will help you learn the machine. Anything over 1/4", or if you can get to it, weld both sides.

 

No professional here, everytime I have a nice lookiing weld, there is little penetration. So I always just 'burn it in' and let the grinder smooth it out.(I need more practice) Only have had a few welds break(less than 5 in 20+ years), most of the time(99.9%) it breaks at a factory weld, so I don't feel bad about my welds. Good luck and keep practicing.

welding 1/4" or thicker material you can bevel your steel  to help get at good weld

get a couple good books on welding - they will help explain a lot or how to weld different thickness of steel

 

once you have learn how to get a good flat weld try welding pipe

it is a little harder - more grinding to get to piece to fit together

Your coming along fine, as you get going you have a good looking weld. You need to dwell a bit mor at the start so you get heat into the parts. Once you get your puddle started , then continue. Same thing at the end, you stop for a second then back up a tiny bit. This helps to stop craters and cracking from cooling.

So i welded up this little stick figure, just to try out welding pieces together. What do you think? ImageUploadedByTapatalk1403038627.611764.jpg

I have to wire wheel it or something to make it look nicer lol.

I believe all the white stuff is from the flux but looks good. Try a wire brush to clean up something that delicate.. Try welding a but joint on flat pieces to check for penetration. Making sure you get enough heat to discolor the back.

Does anybody know if i can put a metal cutting blade on this dewalt chop saw? ImageUploadedByTapatalk1403139066.279622.jpg ImageUploadedByTapatalk1403139086.329374.jpg
Im going to need to cut 1" square tube for a bike rack my mom wants me to build. Just wondering if i can use the chop saw to get a cut that more square than an angle grinder.

So my aunt maria's birthday is this weekend. And we are going over there to visit and celebrate. So i figured, i'll weld something up. I was browsing the internet for ideas. And i found a flower for a garden made from washers, flat steel, and a steel rod. So here is a pic of what i was aiming for ImageUploadedByTapatalk1403226014.896963.jpg
And this is what i made... ImageUploadedByTapatalk1403226041.446517.jpg
I kinda over built it, as i do with anything i build. This is the back of it...ImageUploadedByTapatalk1403226090.647915.jpg
Im just going to clear coat it, to prevent rust. I like the blue heat tint from the welds. by the way, it is completely welded from the back, no welds on the front of it. What do you think? Close to what i was looking at? Better? Worse? Give me your opinions. 😃

It came out very looking good :dancingbanana: , in a flower garden it would stand out but at the same time blend in with the blue heat tint like a silver petal blue core flower.

 

It is welded up so good i'll bet you could use it as a hammer :thumbs:

I think it flat out suxs so bad you should never weld ever again !!!




Kidding, kidding, i know, im a jerk, anyways, it came out very looking good :dancingbanana: , in a flower garden it would stand out but at the same time blend in with the blue heat tint like a silver petal blue core flower.

It is welded up so good i'll bet you could use it as a hammer :thumbs:

Lol thanks, i know the beads aren't the best, but it will hold. I gotta practice on my beads more. But for just starting to weld a few days ago i think it looks pretty good.

Naw, it is not the looks of the bead that matters but the quality, try swirling the pool instead of zig zag.

 

On a V or step between the metals (god my discriptions suxs) use a stepped C pattern.

I was doing swirls, maybe not enough of the swirl motion. Ive got the day off from school tomorrow. So ive got some more time to practice.
Im going to make another one for my chemistry teacher who is retiring after 30 years. So i have to get some more washers tomorrow.
