just another "critique the weld" post

well, finally done with painting the house, so i had some time to practice my welds.

whats wrong with the end of my weld here? going too fast?



backside of the same plate

If it's Mig too, fast of travel speed. If you are a beginner a good book to get is The MIG Welding Handbook by ESAB. Your local welding supply store should have it or be able to get it. Great reference for speeds/feeds, Torch angles, Puddle circulation, ect.


And listen to what ALLEN has to say.

yep, taht was Millermatic 175 with flux core wire

Sorry,

I've been deathly sick.....

Still am to some extent.....it's so sad. I've lost my voice and I can not really talk about e right now.....

Stop running beads on flat steel. You'll go nowhere fast.

Make some "T" joints. Weld both sides. Weld them to each other.

Weld until you're sick of welding.

Once you've masted a basic fillet weld, you can progress from there, and the rest will be easier.

Position the nozzle at 45*/45*. Drag it on the steel if you have to. That's allowed.

Relax. Do not tense up. Most people do without realizing it.

What shade lens are you using?

Post more pics as you progress.

Pic number 3, weld number 2.....looks good. The others look so so, and I don't see any major defects that would scare me. But, it does look like you're running just a bit cold. Lower your wire speed or raise the voltage a tad.

(Did you use the same setting on both the front and back sides?)

Also, please crater fill at the ends of your welds. Weld travel stops, but welding continues for a second or so to "fill the crater" in. Otherwise, that's where the crack will start.

Get well soon.

I do need to gather up some scrap metal and just practice and practice. But with baby coming in two weeks I might not have that much time.

I have to look it up. I bought a cheapo helmet with my welder.

Used the same setting everywhere. I will try lowering the speed and raising the voltage.

OK, I haven't been doing that.

What settings would you use when welding thin metal to thick? Like unibody steel to 1/4 plate?

What settings for body sheetmetal to body sheetmetal?

Thanks,
Denis

Baby in 2 weeks?

Mine'll be here in 5 weeks.

Check the welder for the proper settings. Should have a chart in the owners manual or inside the cover where you change wire. Set it for the thinner metal.....

Thanks for the advice guys (Allen too!)

Denis, any news about the baby yet??? Or did I miss that too?
