5 ton,sureley you was joking


You mean to tell me that you are using a 2 bolt configuration on a 40ton hook You must have a **** good insurance guy I didn't know that commercial inspections would even pass a 2 bolt hitch, its all 4 or 6 bolt up here. Even then, I don't build them, only repairs, because designing something and having it go faulty is a very good way to end up in the washing machine, unless you have a design and engineering liability policy and the credentials to back it if it goes to court Maybe its because you guys have nice smooth roads down there

I remember who you are now! Here I was thinking you were the sewer guy who had the run in with Lowes over a 200.00 $ payment!

mud board

That's what I thought too, back when there was that whole thing about the hitch.



I carry plywood partial sheets on my truck for that reason, they work pretty good, unless its real soft stuff, then a couple rocks or logs underneath work well. A pallet would be ideal, but I never had the extra room, and never think about packing something like that with me, until I get to the jobsite, that's why I just keep the plywood on the truck I often thought a little 2.5'x5' aluminum fold out table, that only has 6" legs would work well.

Coal grab a piece of extention ladder about 3-4ft. long and bolt a piece of plywood or plastic to it . very light and easy to store .I'll post some pics of mine later. Jef

Welding on this high pressure gas line was not just another day for me.

Years ago I was working in the San Joaquin valley. Everyday I drove by a pipeline project. I was amazed at how ruff they treated the pipe when installing it in the ditch! The sidebooms had huge Tommy Moore blocks on them. Must have been 4 or 5 sidebooms all working with different boom angles, and they would just travel along side the pipe all in unison. The first sideboom picked the pipe off the dunnage, and all the other sidebooms were spaced so many feet apart and with different boom angles, the last sideboom laid the pipe in the ditch. Pretty slick system!

120.00 pile,and still no payment.work done around thanksgiving.

this hitch

[Sberry]

My bud is an auto mechanic and when he works on some junk he makes them pay in cash, no receipt. I had some broad a while back want me to weld a hitch mod on this junky pickup with a working brake on one wheel, she gonna hook on a big azz horse trailer. Ha, I told her, if I ever see a trailer hooked to this truck I am going to call the state troopers. She got a big whining sob story, well, if she can feed a bunch of damm horses she can drive better than that. I weld all kinds of stuff on, even if they try to sue me they have to prove something cause I wont settle, I make them take me to court. Back on track, it looks like if I keep my 200 long enough I can sell it and retire. At one point they wernt worth much, now it looks different.

Reading all this talk of the Lincoln SA 200, 250s , the Classics engine driven welders. It makes me wonder how their "superior arc quality" in comparison to other engine driven units compares to say a non engine driven welder like an inverter or any old power supply, like a dialarc, or DC 400?

Ive been running a sweet little Maxstar 200STR and really love the arc, and can really notice the difference between it's arc and say an older dialarc. Now can the Lincoln Engine driven units that Ive mentioned above really have a superior arc? if this is so id really like to try one out and see for myself.

now back to your ?.i have welded with a 71 model sa 200 gas and a round bout late 80s 250 diesel,and they do weld nice.i have owned 3 bobcats,and a new trailblazer and prefer the trailblazer arc,big difference imo.i also have a 89 model dialarc 250,arc is similar to lincolns and trailblazer imo.i believe when you get into these top grade commerical grade machines you will not see a huge difference in any of them.to me kinda a personal preference thing.i welded with a lincoln 305 this weekend,and to be honest i feel it is so close to trailblazer,flip a coin.or do what i did and buy the machine you prefer or offers the best deal and service and support.



im gonna open a can of worms here,but the biggest difference in these machines are hands.those things holding that electrode holder.just find what you like and feelcomfortable using,and try to stay away from buying just cause so and so has one,or says his welds better,i see that a lot on this board.that machine dont change the outcome(when comparing the top of the line ones).

[Sberry]

I have to think about 95% of the argument is psychological. Blind taste tests prove it all the time.

Isn't Weldingrod the same guy or am I losing my memory already

Weldingrod, no need to get defensive, well not with me at least, I never re-opened that thread or said unsubstanitated things of your workmanship, like your welds were of poor quality. I've been minding my Ps and Qs, hopefully you do too

That's a fantastic idea, wish I had thought of that Thanks.

Pretty slick system!

It may look ruff, but our world the pipe is sacred and treated as such. The lowering in tractors have cradles with plastic wheels that travel along the pipe without damaging the pipe. The pipe is jeeped, that is a jeep is run along the length as the pipe is lowered in. Any holidays (places where the coating is damaged, they are found by the jeep, which tries to pass a current thru the line pipe, and only succedes where the coating is comprimised) are repaired before lowering in. There are one or more coating inspectors on hand for the lowering in process, as well as the ditch inspectors. The archeology inspectors are also on hand for anything related to excavation.
Welding inspectors swarm over pipeline jobs, sometimes one inspector per welder. they number joints of pipe, number welds, put station numbers on the pipe, lay out any cathodic protection as to where it goes, make sure the procedure is followed, make visual inspection of all welds, build weld maps, ect., ect.
Grinding marks or arc marks are almost always a cutout.
Line pipe of course comes coated, usually with an epoxy or poly type coating. The ends are bare for a few inches to allow welding. After the welds are made the area is sandblasted and gets several coats of a hand applied coating (dope).
All of the welds will see several layers of inspection from visual to x-ray to the pressure test.
All of this because the pipeline is going to be expected to perform for well over 40-50 years underground.

Line pipe usually isn't even allowed to come in contact with the skids (the wood used to crib) instead a pad has to be under every point of contact.

When you make your living welding downhill line pipe, under harsh inspection and in a very fast paced high pressure enviroment, all day, burning a 50 lbs. can of 70+ threes in a day, you will very quickly be able to notice the very great differences in how different machines perform that task.
And like most sensible human beings you will gravitate to the tools and equipment that make your day as smooth, easy and pleasant as possible.
In a world where repairs mean you are run off (and this results in a great loss of income), often after driving a thousand miles or more, people use what works the best and makes for the most comfortable, pleasant day possible.
To the neighborhood shop, running mig guns on junk iron all day the difference will not be a factor but it's a major deal to some.

Hey JT welcome home ! You through building America for a while?

Thanks for posting this information, I guess I missed a lot driving by at 50-MPH .
Always like learning how other crafts do their work.

Ok I know we’ve worked in the same refinery before, but different times. Now that pipeline I was talking about must have been 1981 or 82, and it runs besides J-5 road between highway 580 and Brentwood, don’t suppose you were there?

No I wasn't there.

I was in the area between the Bay and Modesto a couple of years ago making anomily repairs on the 24" Mobile line laid during WWII.

As for "Building America", with a little luck I'l be in the mix pretty heavily for the duration of our current pipeline construction boom. And when that's over I'm hoping for a Pile Driving boom so I can weld cans ; ) and that's the truth. Next to pipeline work I like big bore heavy wall cans quite a bit. Like a pipeline turned sideways and the pay is very good. Similar mentallity as well.

I just got a new to me 1980 pipeliner that I really like so far.

Have a Day!
