Welding Videos

[Java]

I've been trying to refine my technique and have found a few useful videos for me, hopefully for anyone else here who is learning too. In welding class at Club Workshop the instructor stressed preparation heavily, and this video shows how/why:

This is how to weld thin steel to thick steel, specifically expanded sheet.

This one is about sharpening drill bits, I've found metal eats the edges pretty quickly. I've never tried sharpening them on the outside edge of the wheel before I saw this, it is 100% easier and better than the round edge. I have a standard bench grinder so I can't cut the inside like he does, but I've found that just continuing the cutting edge grind can do the same thing.

Harbor Freight 90 amp weld test, at 5:00 or so he cuts the welds open to see how they penetrated. IME Lincoln wire is great, throw the HF wire in the trash. I still mostly just tack with mine, but I'm liking it more and more as I use it. I have some scrap I want to try welding / cutting to see how it does for me.

Another trick with welding thin metal to thicker metal is direct your torch (45-60 degree angle) towards the thicker metal and pull your puddle to the thinner metal.

[greenramp]

in the above picture I agree with where the red line is in contact with the thicker material slightly inboard of the joint to be welded, HOWEVER the angle should not change leaning toward the thicker material. This will GREATLY weaken the thinner material and cause the weld to undercut. If anything a weave should be incorporated into the bead with greater time spent on the thicker material.

just my:2c:

HOWEVER the angle should not change leaning toward the thicker material. This will GREATLY weaken the thinner material and cause the weld to undercut. If you adjust your heat setting to the thinner material, this would work. What you end up with is a fillet suitable for the thinnest material.

If your equipment and/or process are "too hot" for the thinnest material, using the arc to "punch in" to the heaver material, and draw enough heat to the thinner material, you can obtain similar results. It is a simple idea, just not so easy to execute.

I'm scared. This is a vehicle! With rebar! Atleast he speaks eloquently...

Here it is, with his wife driving. Listen to the commentary, it's like he's watching a different video.

:eek::lmao::lmao::lmao::lmao::lmao: Using rebar for a buggy cage is a little more redneck than I is.

Some good ideas, especially on vertical welding.

This is probably what Brucker learned in Pre-k, but it was good basic info for me! :thumb:

Have you found any more good videos to share?:)

[Java]

no, I've stopped learning. I only have the HF 90amp flux core welder, and it does well primarily with .030 wire, 1/8-1/4 inch metal with deep beveling, about a 1/8 gap, and only works well horizontally. Everything else I try turns into grinder practice. I only use it on the high setting with the speed on 7- in a nutshell, my welder is so limited that I've learned all I can use until I upgrade.

[Java]

so my garage got robbed a couple of days ago and they stole my old HF welder. It was the old blue one, I bought it as an impulse item about 10 years ago and just accepted its flaws. I had to replace it, and after shopping around I realized I can't afford to upgrade now, and as a hobby-welder I can't justify spending too much anyway, so I bought the same thing again. I was pleasantly surprised, it is SO much better than the old one, mostly because they've redesigned the wire feed mechanism and it makes much smoother and more consistent beads than the last edition. I may not upgrade...

[Hypoid]

I hope it works out for you Paul! Better lock your "good" stuff in the house, wait for the low-life to come looking for the replacement...

[Bob]

Yikes! That go cart genius probably thinks everything is over engineered and gold plated, so he'll do it the right way! I hope whoever drives that stays at low speed on flat ground.

this came with my new welder, cool little reference

This was interesting, here's the text from the youtube description:

"Discovering a performance tweak on the Harbor Freight 90 amp welder (the replacement for the one in some of my earlier videos, as the old one fried itself after giving good service for a year or so). Running a 120v welder directly off the generator gave some great results on this to the point that what had originally been a bit of a gamble just to get the trailer back out of the woods turned into a permanent fix done on site. The next day, I still had the generator in my truck and was called out to do a welding job in a guy's garage. He had a gas shield MIG welder which had provided insufficient power on his hotrod frame, but when I pulled the generator out and ran the welder directly off the generator, it did just fine. I think it is because the power actually behaves more like a 130 amp circuit on the generator plug outlets. The welder also went a long time before overheating."

I feel as though I have watched so many youtube videos I have a basic understanding of welding. Now I just need to get my hands on a welder.

I have my hands on a welder, now I just need a 20amp circuit to my garage :(
