Thanks for the help people.....sounds like im going to be trained as the main welder...no one else has the hrs of welding expérience as I have on nights..they are giving me a bunch of scrap and go to town...and now they want me to learn TIG too...

I'm pretty experienced with mig welding carbon steel and spool gun aluminum, I've just started a new job at a food processing plant as industrial mechanic. They will start training me to stick weld stainless steel, just wondering how different it is to weld in this process? Any info would be great..

Thanks for the advice...but after talking with the plant manager and our engineer....we got a crane in to remove the steel mold, and will remove the drive shaft and mounting plate and send them out to get done by a outside company..crane operator weighed tank in at just over 10,000lbs..I trust my we...

I'm an Industrial mechanic at a plastics and fiberglass plant...my welding skills are good..had training an near by collage and just on the site training..lol Anyways we make fiberglass septic tanks, and our biggest mold is a 8 ftr(diameter)..and 30 ft long made of steel...engineer at work estimated...

Here's some better pics...got part taken off today and cleaned and beveled the cracks..it worse then I though..
Thanks for the advice.

Material is just reg. Carbon steel I believe. This winding machine is very old..I will get better pics tomorrow once I have it apart.

I'm an Industrial mechanic at a plastics and fiberglass plant...lots of older machines and equipment. Well during one of my machine inspections today I found a badly cracked shaft...it's been repaired once. Not sure our miller 250 mig is the right welder for the repair? When I repaired it last fall ...

I'm looking at repairing a stainless steel dryer drum that has cracked at one of the welds inside. Dryer is an older model, and the drum is no long stocked. I have a lincoln 180..I have it set up for flux core..but also have argon gas and the spool gun for aluminium. If I get the right wire can i do...

Using 4043...yes i now realize its not the right filler..but it came with the gun. And im still learning this aluminum welding thing. Crap...way différent then reg steel mig or fluxcore..

I still have our original owners guide, said hull was made with .100 gauge aluminum..boat is a 1997 Legend 16.5 ft boat. Thats my best info to go on...boat was given to me be by my dad.

I had to look up 100 gauge, and the source I found said the equivalent is 0.001". Can that be right? That's 1/10th as thick as aluminum foil.

Sorry, my mistake...i missed the decimal point. .100 gauge..that looks better. Lol

I'm also starting to think i might need to fill in from the other side to? Any thoughts on that? Would mean pulling the floor out...but i want this done right..

Well I started on it today..grinded out the crack area and cleaned it up nice. But after closer inspection I found that the crack started because of the aluminum is woren down there from beaching the boat over the years..so the it's very thin there. I had to be very careful as I kept burning holes i...

Just looking to see if anyone here has expérience in welding aluminum boat hulls..I have a 16.5 ft fishing boat with 2 small cracks at the bottom from at the bow. Leaking water bad whwn I had it in the water..I have a lincoln 180 with a 100 spool gun. IVe done a fare bit of aluminum welding at work ...

Its an 1/8 of an inch, cracks are at the back brackets that bolt on the trailer bunks..lots of stress there. I'm also worried because i just upgraded to a bigger 40hp motor that is about 100lbs heavier then the old motor...

Doing my spring maintanance on our boat and trailer, and found some cracks on the galvanized trailer frame. Can i just remove the galvanized coating and weld the breaks? Also I'm using a flux core welder, I'm aware that the gases from heated galvanized coating arent good for your health..so any tips...

That makes total sense, I've adjusted my flux core technique with way better results.

I'm pushing, it a techniec I was taught by the millwight I trained under about 4 years ago when I started welding..but then I was mig welding..not using flux core.

Well over the weekend I was at our local hardware store, some of use might know the store. Canadian tire.....I thought for now I could get away with going cheap...got a 14" adrasive cutting saw. Burnt out the motor after about 8 cuts. Took it back and got my money back...told my fiancee"se...

Yeah, well the ones I've been looking at come with the 14" cutting wheel that looks like a big cutting wheel for an angle grinder..so your saying these bigger cutting wheels flex when cutting? Ummm, i may have to re think this...

Well as I'm getting more into metal work in my garage, I'm needing better cuts. I'm getting tired of using the Zip Cutter. My budget just can't allow a liquid cooled metal band saw, plus my garage getting well below freezing when I'm not working in there. So I'm looking into these Chop saws..Price i...

I should have relized this would happen, where I work as a millwright we have many ventilation and air make up units. I work in a plastics and fiberglass plant. I see first hand what can happen when you draw out to much "dirty air" and dont replace it..we have old make up units..not near b...

Yeah I was a little worried about this one...as soon as I turned on that blower. I could feel the garage temp dropping fast, it like -20 Celcius here today...Im not sure exacly how im going to tackle this new problem..just know with the amount of money ive already put into this garage...my fiancee w...

I'm in the prosses of setting up a shop/welding area in my attached garage. So ive got an exhaust blower fan up and mounted on the wall, and got the hole cute..I'm planning on running 6 inch ducting from it to an exhaust hood that will hang over my future welding table. My qeustion is i started it u...
