ROPS Welding

[thingy]

Mike,that don't make much sense to me anyways. Number one,,it don't work that way in welding,,if you don't know what material it is and how they welded it,,[filler,preheat,interpass,postheat etc],you can't just assume you can get your mig out and weld it with whatever.Not really talking rops here,cause I know you can weld on them,,just your theory is all.
And number 2,don't all rops have a welded plate of somekind on bottoms to bolt to tractor,,mine does. thingy

Number one,,it don't work that way in welding,,if you don't know what material it is and how they welded it,,[filler,preheat,interpass,postheat etc],you can't just assume you can get your mig out and weld it with whatever.

In other words, if someone doesn't know all this, they should not weld anything to the ROPS.

not really talking rops here,cause I know you can weld on them,,just your theory is all.

I didn't present any theory. I presented a fact. It is possible to safely weld on the ROPS because the factory welds hinges on the square stock that makes up the ROPS.

Of course you can weld on anything Mike,,its just you gotta know what your welding on,,it could be 9 percent chrome,[it looks just like steel],in a case like that you gotta know how to weld it,what to weld it with,etc. Some things gotta be stressed relieved,,after welding or you'll get cracks,,some things gotta be preheated to a high temp,and cooled at a very slow rate,,,the list goes on,,,so just cause you see a weld on something that looks like steel,don't mean you could just go ahead and weld on it,,thats what I was calling your theory.
Anyways,,way back on first page I think,the guy said he was going to bolt it on someway,,,so,,,,thingy

 

[MikePA]

I give up.

 

[thingy]

No,I wanna give up first,,,[you are all right mike],,thingy

Roy.. in case you don't know by now.. You are simply 'P' - ing in the wind if you try to have a rational debate with thingy.

For this scenerio.. he simply doesn't ( or refuses to ) understand that reguardless of whethere a persons weld does or doesn't actually weaken the structure.. the fact of the matter is that it will almost certaintly void the rops certification.. and with that gone.. that opens up an entire can of worms as you and many others point out.

I've argued the same on many threads in years past... It usually ends up with 2 factions... The people that feel it is fine to cut/weld/drill the rops.. and those that fell that you shouldn't.. reguardless of IF it does weaken them or not. Somewhere along the way there are usually hard feelings and the terms 'wussy' and safety police get thrown around.. and then that funny padlock symbol shows up on the thread after it hits about 5 pages in just a few hours.

FWIW.. I agree with you 100%.. there's simply no 'good' reason to modify the rops for a light bar when a clmap on one is SOOOOO easy to add, and doesn't violate the no cut/drill/weld certification on the rops...

"Roy,of course thats the reason people asks questions,,,I ask some myself,,but its nice to get the right answer,,this has evolved into a legal issue with manufactor,not if the guy can weld a light bracket onto his roll bar,,there may be reasons he don't want to,,just saying from a welding point of view,they ain't one,,,and again,that was the question."

The manufacturers state it, safety organizations state it...Don't modify the ROPS
Thingy, unless you've done testing per the SAE spec...you really can't state welding doesn't degrade the ROPS because you don't know.

Reckon that's all I say on this topic... It's going in circles now.

Soundman,is that you? Talk about 2 cents,,,,just kidding you soundman,your my favorite! THINGY

Actually, I've already done that, at least with New Holland. A couple of years ago, my dealer asked if I would be willing to speak with a couple of NH engineers who were visiting the area and wanted to speak with owners about how they were using their tractors and what they liked or disliked about it. Of course I jumped at the chance. One of my suggestions was that it would be nice to have a nut plate or some sort of mounting tab to mount lights on the ROPS as it came from the factory. I pointed out that a lot of people were drilling or welding something to accomplish this (and to support cupholders and the like). In the interest of safety, having something already there for the purpose would make a lot of sense.

They did write down my suggestion, but I never did see it appear on any of their CUTs. I'm assuming that this is easier said than done. As soon as they drill or weld, they've got a more complicated system to do the safety tests on, and another area of quality control to keep an eye on. Any screw up in the manufacturing process, and they've opened themselves up to significant liability.

I do not really know this as a fact, but more as an "informed guess"

I doubt they would want "extra" tabs etc on there for folks to mount their own stuff on, as they would then not have control over what got mounted. While most here would mount something logical, usefull and reasonable, there would end up being some court case where some guy mounted a boom pole off the rops attachment brackets and rendered his rops unuseable.

I dont know why im feeding the trolls but for some reason i find myself doing so.

Have you actually LOOKED at your ROPS? I know mine is welded on from the factory.

You think the factory goes to all the trouble of re-heat treating the ENTIRE structure after they have modified it themselves?

Ill be welding brackets on mine for various things. I have no worries about it affecting the structural intregraty of the ROPS.

schism,you must be talking to me,,if so we are on the same side here,you need to go back and read from the beginning my man.
And to answer your question,no they wouldn't post heat treat it after they welded on it if it needed post heat treatment,they would weld things on and postheat the whole thing than paint it and bolt it on.
You seem to have gotton in on the middle of the conversation,,my postion was it wasn't made out of anything really special and it wouldn't require post heat treatment, you buddy thingy
