Re: Welding Discussion

So in fact you qualify as an "Experienced welder" ...:)
Only if 4 years of formal welding school and 41 years in the industry qualifies you as being EXPERIENCED?
;)
I started welding at age of 13. At age 16 I placed 2[SUP]nd[/SUP] in the State and 3[SUP]rd[/SUP] in a national competition the following year. I passed my first 3 and 4G combo plate certification to qualify to weld at the Bethlehem ship yard at the age of 17. At age 18, I took the job of welding foreman for American Tank Corp. building municipal water towers and oil and chemical storage tanks.There I passed my 6G Pipe certification for nuclear and power plant work before I was 19.

Several years later I went to work as a welder for a instrument manufacturer. There I welded everything from small instrument probes that you needed a magnifier in your helmet to see to large on-line stuff that weighed 10-15 tons.

Welded a lot of exotics on that job. Aluminum, Stainless, Inconel, monel, hastelloy, titanium, magnesium, nickel, silver, etc. Welded a lot of lead making radiation containment enclosures. I ran
the shop for 7 years before moving into Engineering then on to Sales where I am today.

Welding is a hobby for me anymore. Mostly repairing equipment here around the farm or welding up stuff for the neighbors. I've done some repairs and restoration of iron artifacts for the historical society and I do some ornamental iron work for the local park service from time to time.

Re: Welding Discussion

Hard to imagine being able to do aluminum welding very well with a MIG set up. I do TIG and its hard enough doing it with that and AC!

Re: Welding Discussion

Actually Bruce58 aluminum MIG welding with the right equipment is very easy in the flat or horizontal position. My weapon of choice is the Miller Aluma Pro for such welding.

Dingbat you are right on......My welding experience of over forty years is very similar to your experience. Welding cannot be explained in a "nut shell", as there are so many variables in material, process, and procedure. I just wanted to clear up that 7014 is not classified as a hillbilly rod. It is considered a "farmer" rod. True hillbilly rod consists of using a wire hanger with the TIG process.......I also want to mention that professional welders carry insurance. A person should not piece together a trailer with a bird dropping....globular transfer method, to only have the trailer break and go careening across the highway into a oncoming school bus.

And yes.....wear your PPE.

Ayuh,.... Due to the fact, that I don't own a tig, I mig aluminum quite often...
Harley motor cases, to dumptruck bodies...

The semi-rigid bimini I post pics of on occasion is also completely welded usin' a mig...
While the bimini was welded up with an old Century/ Snap-on 24v battery powered rig,...
I've since moved up to a Lincoln Magnum spool-on gun set up, powered off an ole Lincoln SP-200...

Weldin' aluminum successfully hinges on the cleanliness of the base metals...
Wirebrushin' with a SSteel brush, Just before weldin' is how I get there...

I agree that there is the fine line in MIG welding aluminum and having a pool of molten aluminum splatter on the ground. with that stated, I have a complete teflon lined whip that I use for welding aluminum with my Lincoln MIG. It works well, however does take a bit of practice. the key is usually a bit of pre-heat. I use an industrial heat gun for that to keep the surface clean.

if I want really nice looking dime rolls, I then head over to a friends house with a water cooled TIG and proceed from there.

Back to the other thread on welding. having been in the welding industry for a while, and using nearly every form of welding for projects at work from gas (2-cycle custom exhausts) to arc (in its various forms from resistance to MIG to TIG to stick) to friction (both vibratory and spin welding). I just sat back reading the banter and ate my popcorn

Re: Welding Discussion

Hopefully kidding right?

MMMMMM, Bacon!!!

Yes and no, I never took any formal training, so when I picked up a mig (wire feed) to patch up truck/utility bodies I hung out at the local fab shop my buddy owns and he walked me through the basics.

His words to me that stuck is once you get the heat and the wire speed just right it should sound like bacon frying, and the other big point he made is you can't weld rust.

So thats what I learned in my one day wonder course.

(so now if I could learn "how not to" get the slag building up inside the tip I would be a happy camper)

Cofe, "I just wanted to clear up that 7014 is not classified as a hillbilly rod. It is considered a "farmer" rod. True hillbilly rod consists of using a wire hanger with the TIG process."

Thanks for the post, I stand corrected again. :facepalm:

I grew-up in farm county so the farmers called 7014 Hillbilly rod and the hillbillies called it farmer. LOL

The truck's battery, jumper cables, and a coat hanger. Yea, I've done that. Does that at least get me hillbilly status?

Ayuh,... You can either buy a anti-splatter spray, or dip, or use "Pam" cookin' spray to coat the inside areas of the nozzle...
With that done, it's a matter of knockin' or wiping it clean...

Re: Welding Discussion

I have heard many people describe when your welding it should sound like frying bacon. I dint think I have ever heard a weld that sounded like that and I work with a crew that does that all day long every day. That would be one hot pan.

I thought about commenting on welding but there is just so much to know. Anything from different rods/wire/gasses to do different jobs to using different products to do the same same job. Some jobs/equipment you push the puddle others you drag the puddle.

Just to much to generalize the trade.

Re: Welding Discussion

Getting the wirespeed/voltage combo right(bacon sound) is just one aspect. Selecting what will get you proper weld penetration is another. You could run beads all day long that may look ok but unless you get enough penetration into your work piece the weld will fail.

If your getting slag build up inside the tip, you must be using self shielding wire which doesn't require gas. You won't get the bacon sound using that wire and the slag build up comes with the territory with that type of wire. That wire is great for working outdoors but if I am working indoors, I prefer to use plain wire and a shielding gas.

Re: Welding Discussion

Also, no welding thread would be complete without "DO NOT EVER USE BRAKE PARTS CLEANER" to clean parts before welding..... unless you have a death wish
