Right back on that Iron Horse
Remember this?
Well The Mad Welder is back.
I’m back arc welding again. Man, I much prefer arc welding.
Tomorrow, some pics of my progress. Getting close to the end now.

These are the pieces that I made today. The were my mock pieces for the test. During the test I’ll be making pieces just like those. Wish me luck, I finish up on Friday week.
There’s a surprise between now and then, stay tuned.

I know this looks like things you can make with a “My first welder” kit, but these are examples of the three basic things that are done with gas welding.
On the left is a box section which is made by welding together four pieces of steel at the corners.
The middle is a butt weld, which I’ve talked about before.
On the right there is a T joint, which I talked about in the last post.
Everyone should try to learn one new skill every year. At least one per year.
Specialization is for insects.

The T-joint. So called, because it looks like a T.
Weld both sides, and make it look good.
I love acquiring new skills.

The latest thing is seamless welds. You have to achieve full penetration of molten steel right to the bottom of the joint. You can do a visual check for this, but to really be sure you have to cut the piece in half and inspect the weld.
I think that’s a pass.

Sadly, the last beard update. Click through for the results.

Check it out. I welded a piece of pipe to a piece of plate, and the weld is water tight. It’s water tight, which generally means it’s gas-tight. And that’s what we’re looking for.
Tune in for more progress.

You know…. sometimes it’s just not going your way and you can’t seem to get it together.
So occasionally you make your own fun.

Here is the progression that I’ve been making since I started ths course.
The joint on the left is a lap joint: connection two offset pieces by welding the edge of one to the middle of the other while both are parallel.
The middle joint is a fillet weld: two pieces connected at the edges at a 90 degree angle, or whichever angle is necessary.
The right joint is a T-joint: the edge of one piece connected to the face of another at a 90 degree angle, welded on both sides. This is by far the trickiest to date because once you’ve welded one joint the nature of welding the second joint changes. There is extra metal on the other side of the joint, thus the torch has to work harder to heat the metal to make it liquid.
I shall continue to post when I make further progress. Or I may post every day, I’m not sure.

Today the subject is butt welding. Yeah, laugh it up.
Two pieces are place side by side and tack welded into place. A gap of at least 2mm needs to be left otherwise the weld won’t penetrate between the pieces, it’ll just stick on top.
It’s easy enough to do when you know how.
