Welding Techniques - Pic in post #28.

***UPDATE***

Was up at a buddies garage today and tried my hand at welding. He has an 80amp 110v off brand walmart special and of course its gasless Flux Core. What a way to learn welding, lol.

Here are my lessons learned;

1) Auto dark helmet - he didnt have one, point and shoot sux, I missed my mark many many times. He would ask me if I got it, Id say, nope missed by a mile and just keep plugging away.

2) I had first time welder jitters, you know what that is, when you first strike the arc, hear that sound (like being electricuted) and then you jump and then stop. lol. I probably started and stopped a million times till I got use to it.

3) I learned all about wire speed. On a scale of 1-10. My buddy would weld at a 5 with heat on Low. I had to drop the wire speed down to 3, I couldnt keep up with it at 5. Lesson learned.

4) We were welding in the worst possible position. Inside rocker panels under the truck. I learned that angles sux and position of gun is important and not being able to see didnt help.

5) Learned not to lay directly under what im welding. Now I get to turn in a pair of work pants for welding holes, lol. Slag sux

6) I need more practice for sure, this was my first time. lol.

7) I think I can have a nack for this with the proper equipment. The auto dark helmet wouldve made this go alot smoother and I couldve done much better.

8) I had fun and learned alot. We mainly did "stitch" welding because it being a panel as such. So I didnt get to really practice any fancy V or C techniques. I basically spot welded the whole thing.


Pics tomorrow, although Ive already painted everything, so we'll see how they turn out. lol.

Thanks everyone. Once I get better ill post more. :)
 
Right on...

Pick yourself up a little machine and start ta burnin'... It'll start to click... Just takes time... Some pick it up fast others take longer...

And yeah, using your opposite hand to rest your trigger hand on helps keep it steady...

Once you learn how to see your puddle and manipulate it, it will change the way you look at metal...:D
 
Seems everybody has covered all the best tips.

Only thing I can think of is keeping the bead even on both parent metals. Cold lap welds are not so good.

Weld bead only needs to be as wide as the parent metal is thick.

Biggest one is to pick up a welder and start welding. You can go to all the classes you like and they can help but nothing will trump experience. Not even a certification trumps experience which I recently had reinforced.

I don't think you ever stop pickin' up little techniques that work for you. 28 years welding here and still find something from time to time.
 
Look at the metal!

Seriously for a long time I only looked at my exact weld but look around it, especially while practicing when your weld quality is not so important. It helps you understand the weld, you can fix things as you weld I have been able to prevent porosity due to looking around my weld.

So my advice is when you are practicing look around, not just right at the puddle

Well said, kinda what I was getting at with looking at the metal in a whole different way... It's hard to explain what to look for, that's why most everybody says practice, practice, practice...

It's like knowing what's wrong with an engine by listening to it... Even when you point out the sound, some people will never hear what an experienced motorhead hears...
 
yea it was fun. I agree with looking at the metal. On the practice piece, the first thing I did was turn it over to see if I had A: Burn thru and B: that it was hot enough and penetrated all the way thru the metal without burning it up. :D
 
Ok, here is a quick snapshot of my work. I had plan to take more pic when I got home, but my truck wasnt running so I just threw some paint on the bare metal and went to diagnose my truck issue. lol

Remember, this was the first time I ever touched a welder. lol

This was the inside section of the rockers.

Yeah,and sniffing the fumes that comes off galvanized metal is a GREAT cure for constipation!.:doah:."Zinc Chills"...been there & done that more than once after using galvanized steel ductwork for floor patches in my trucks ...had the squirts and cramps for days after inhaling a dose of those fumes,even with a fan and welding it outdoors it still got me!...

Also its worth mentioning here that you should NEVER use Brake Cleaner to clean metal that your going to weld--the fumes will KILL in short order!...read lots of horror stories online about the effects that stuff has on you,its not something to take lightly..


Isn't the Brake Cleaner or choke cleaner danger from Chlorinated mixes only.
I have had no problem with NON-Chlorinated types.
 
I learned the same way most people do trial and error.A few things Ive learned and prefer are take good care of your welder.Keep it clean and use only clean rust free wire.A pre lube/cleaner for the wire before it enters the liner keeps it working smooth and Ive found a .023 or .024 wire works best for what I do which is anything from body panels to 1/4 in steel.A nozzle dip or spray will keep the slag from building up on the tip also.Also be careful when grinding down the welds to make them look good especially with the lap type weld you have pictured.You grind off too much and it weakens it dramatically.If you have any exterior panel replacement to do Id rec getting a panel flanger because the lap welds create more work and require more filler to finish the body work and weld in short bursts just a spot at a time keeping the welds far apart to minimize warpage.
