I wonder if I should do some welding youtube video's to share with all of you.

I wonder if I should do some welding youtube video's to share with all of you.

Absolutely!

I haven’t looked at a lot of YouTube welding videos yet but what I have seen is a lot of demo on angle iron. It would be nice to see some with 18 gauge like our cars. Lap weld, butt, etc.

Also, it’s hard to see what the motion is when they are welding. It looks like a slight side to side movement as they move down the weld. If that’s the case, It would be great to see what you are doing just using a pencil and paper.

I need basic instruction but I’d really just like to learn the right way to do it from someone I trust that knows what they are doing rather than trying to figure it out from the self proclaimed internet pros.

I use a slight back and forth with a wrist twist or for larger patterns a small circular swirl while progressing down your path. Practice this on your test material with the heat all the way up and enough feed to keep the material fill going. Once you get it with full power, then you can back off to adjust for the thickness of your intended work. Ideally it should sound like frying bacon without the smell... hmmm.... maybe my next invention.... (IMG:style_emoticons/default/idea.gif)

Interestingly enough in production/industrial robot's there typically is straight line welds with no weaving or techniques used. Just proper voltage (potential amperage) and wire speed (actual amperage).


On that note it is extremely important that people under stand that Amperage = heat in the welding world. In GMAW /MIG that is wire speed.

My analogy is pretty simple. In a car with manual transmission each gear gives you potential speed from low to high but what makes it go is the gas pedal. So if you consider each gear a potential range then understand that voltage is = a gear range and wire speed is = amperage within that potential range. They have to work together.

Also note that voltage does not = heat.. That is the biggest misunderstanding when it comes to MIG and often weld failures come from that misunderstanding.

So when you weld on your car, do you weld in a straight line or squiggle back and forth.

For sheet metal for a car like ours no reason to weave or do any pattern. What I do is my own version of a pulse weld. You on the trigger then off then on then off and what that does it creates a series of over lapping tack welds that allow for higher heat settings but allows to cool down thus less warpage .. This is common place in the avation world as well. Takes a little practice to get right. You will see the glow from the weld when on trigger as soon as you let off you will see the glow disapate and then its time to hit the trigger again..

Picture its short 1/8" welds overlapping like a stair case if you will..
