All the welding that I normally do is "saving the day" for someone. I don't build or make anything. I just repair cracked and broken stuff. Here is a high dollar intake manifold. It's for an Olds, so it's already a pricey item and its's been ported.

Somehow the pics showed in reverse order. Just start at the bottom.

Just the usual...

Nice work on the manifold and the bike frame. I have welded a bit of both of those in my day as well. We had a customer who used to either buy kits, or design his own, including a recumbent bike that was really funky looking, in a lawn furniture sort of way.

Spent 16 hours repairing someone else's previous "repairs".

Never seen anyone destroy the base metal attemping a reair weld, but such was the case in several places...

Here's what the base metal for one repair looked like with dye penetrant:

Hey,

What caused that?

Hello im a hobby welder these are some bits I welded for my racebike one is a seat subframe one is a Ti exhaust header I modified and one is a flange. I raced the bike at the manx gp at the isle of man. Nothing broke

Hey,

What caused that?

The manifold was 6061-T6, and an unqualified welder attempted to TIG it, using 2% Thoriated, apparently on a transformer machine, too small a diameter, and too much heat. Aluminum should NOT throw sparks as you grind it...

The base metal was full of tungsten spray.

The easiest solution turned out to be, cutting out the entire affected region (in three places), and adding doublers.

My assumption is there was too litle heat to perform the weld, over too long a time, destoying the properties of the T6, and the tungsten spray. This "repair" was doomed from the start.

Fun times. Yet another one to add to the list of "what where these people thinking?"

Nice job on the repair

Funny you should mention tungsten spray. Never heard it called that.

I just did it on a piece of scrap this weekend. I was checking to see what a 3/32" 2% lanthanated would tolerate on my transformer machine. At 230 amps balanced AC it basically sprayed the end off. Back to 1/8" tungsten! Lol

Just sharing a little job ! I did for a mate im no expert remember. Cracked cylinder head. first time I welded it ground it out a bit preheated it and welded it with helium mix and 4047 rod. Cracked right thru weld ! Ground it right out second time and preheated again welded it everything looked ok cracked again on the toe of the weld. welded it a 3rd time this time took the chill of it rather than preheated it welded it and no cracks. Had it pressure tested and might as well welded it with a tea bag leaked every where. Neveragain !! loads of time and gas and rods. But all good fun I guess and valuable experience.
Pictures are wrong way round

Nice looking stuff!

I know nothing about that race, but from the monoshock with the external reservior, I'm assuming there's some "terrain" involved? When you need a shock like that, and you don't break anything, you done good.

Hello Steve s
Basically it's the same coarse as the Isle of Man Tt. The Tt is for professionals and the Manx gp is for amateurs. It's 38 miles a lap on public roads and you do 4 laps. The Tt is at the end of May and Manx end of August. It's definitely a test of man and machine. That bike was a kawasaki er 650. I also ran a triumph 675.

Not my work but my friends where I work after hours.

Into this.

Still a long way to go but it's well on the way.

Oh, what a ripper project.

My project needs a coat of paint and some new wheels.

Big Fat Cup in BFCH by GreinTime3592, on Flickr

This is the cupholder that Braehill (my father) and myself made. It's a mix of aluminum. The strap around the cup is 6061-T6, but other than that, who knows! It was a spur of the moment thing, because I was pi$$ed that I had to try and walk with my walker down the hallway, or around the house. I haven't welded since probably September, as I lost my left lower leg due to a firearms accident at the beginning of October. This was the first time I had welded since, so some of them are a little shaky.
I didn't realize how much I used my left leg while welding until I welded some steel (and burnt through my helmet), and almost fell off of the stool about 30 times because I had no way to stabilize after I had moved my walker. It was especially difficult when doing a cover pass on 2" Sch. 80 in 6G. I had to cheat and turn the pipe in the little fixture that I was holding it in :/ You don't think about how much that would throw you off until you don't have one to use!

[Otto Nobedder]

Welcome, GreinTime,

Your dad told me some of what happened to you. While I can't pretend to know how this affects you, I can tell you from my experience with workers of all kinds in all crafts, you will improvise, adapt, and overcome.

i'm glad to hear you're up and around after your accident!! nice cup holder.

Got to do a little gravy tig brazing last night. Had 700 of these frames to do last night. Nothing fancy just 18 ga cold rolled steel and a 2 inch seam corner to corner.

My job today was to fabricate a refrigeration bypass regulator assembly around an existing motorised expansion valve. The existing pipe is 1-1/2" sched 40 and the bypass to be from 1/2" sched 40. I need to pump out the existing line and make safe prior to tie in. (full of 250psi ammonia).

This is the concept.

Assembly tied in to main 1-1/2" line and in service. Sorry for wierd angle but it was a tight t squeeze to get it all in the shot. I used a CK Flexlok torch to help me get around to tie ins gecause of access restrictions.

Very easy little aluminum chasis on friday. .062 5052 al the only thing that is critical us all the welds must be fully penetrated because they get ground, used 1/16 5356 filler for color matching and strength. Have 700 to do welld about 200 per day so should be done on wednesday.
