Ews?

[TheRealSpinner]

Anybody know what EWS is? I know DOM and ERW, but saw something that said the roll cage was 1 5/8" .134 EWS. Just wondering how it compared to 1 3/4" .120 DOM.

Well, Spinner, I had no idea either. So, I looked at the Steel Tube Institute of North America web site, and it makes no mention of "EWS" tubing. ERW, DOM, and seamless, which you already knew.

Next step: searched for roll cages. Found S&W Racecars, who advertise a 10-point roll cage with the material specification you mentioned. So, I called them! Talked to a nice guy with a heavy new England accent who informed me that all their roll cages were made from "electrically welded seam" tubing. "You mean ERW?", I asked. "I dunno", he said! So, I think we know what we know, and S&W Racecars don't know what we know!

Well Hank, let me get persnickety, EWS doesn't have to be ERW, EWS tube, would be tube that isn't GWS (gas welded seam) nor resistance welded. So a hunka tube run through a mechanized GTAW, GMAW, PAW welder is EWS, but not ERW. Or they got a buncha doods at the slip rolls, and another buncha doods burnin' rod, or wire by hand, you know as penance for debauchery

[fun4now]

well that was prity confusing. maybee some one should check with a few racing sactioning boddies and get a how/how/what ota this after all wouldnt they be the final say so?

Well, there, persnikety one, how is it that I can't find any tubing manufaturer's on this world-wide web who manufacture welded steel tubing by any processes other than induction or resistance welding? I would have expected that the Steel Tube Institute of North America would have some information about this here EWS stuff if it's real, but they don't. Seems like GTAW/GMAW wouldn't be fast enough anyway. PAW maybe, and SAW probably, but the only thing I know of made with SAW are HSS's.

It would be interesting to find some info on the EWS stuff if you know a link. My thist for knowledge cannot be quenched! Even by vodka!

first off james i simply said hi to spinner because he is the only person on this board other than myself from chico, ca.
2nd if i was that interested in tig i would be running the unit i have hooked up to one of my miller engine drives for portable work. its sitting there with a brand new full 180 cf bottle of argon. all i have to do is light it off and rock and roll. but so far i haven't found the time to light it off. come to think of it i don't even know how to light it off . i don't tig but its on my list of things to do when i get older. oh wait i am already old so that excuse sucks

Jim,

What ever you do, don't start to tig. It's like watching the lord of the rings and wondering, how did they do that? I am in the process of building a cart for the Spectrum 375 cutter, and I decided that I would only build from materials laying on the side of my house, and I would tig everything ... well you don't want to know how many times I wanted to fire up the MM210 during this build, but so far I have resisted Funny thing is that one of the local kids dropped his old dirt bike and came to see if I could weld the clutch cover. It looked to be some sort of 3000 series cast aluminum, soaked in dirt and grease for the last 30 years. After I got it cleaned up I tried to tig it with some 4043 filler, wow what a mess that was. So I used the 3035 spoolgun off the MM210 and problem fixed, but I still intend to complete the cart with the tig anyway. Oh yeah, I don't what EWS tubing is either

didnt mean to ofend, it was a just a joke. sorry if ya took itthe rong way. it was ment to be pointed to how nice the dyn's were not that you would only say high just to use his stuff.

thats an interesting take on TIG welding. i cant wait to be frustrated by it

[hankj]

Yeah, James. You wait! I'm almost ready to send a bribe and a plane ticket to Engloid! I just can't get the time I need to sit down 'n git 'er done! 20 minutes here and there ain't gonna get it!

The terms DOM and ERW have become popular in the last few years because of the number of people welding tubing on their vehicles with 120v migs. What your average hobby/garage guy buys as dom was erw before it became dom. Don't tell them that tho, some of them get really defensive
True seamless pierced mechanical tube can be pretty expensive.

Been waitin' fer ya, JTMcC. What about this EWS thing? I figure if it's real you'll know something abut it? I can buy into Pumpkinheah's theory that it could be welded by some method other than inductance or resistance (both of which are called "ERW" according to the manufacturer's sites I looked at) but I don't see how you could produce a lot of it with GTAW. Maybe GMAW or plasma, but you'd think it would be all over the place if a company is advertising roll cages made from EWS? I can't find a supplier of it anywhere......

Maybe it was a typo

You will really like it I think, the truth be told a good percent of the everything I do these days is Tig welded.

[Sundown]

Yeah, James. You wait! I'm almost ready to send a bribe and a plane ticket to Engloid! I just can't get the time I need to sit down 'n git 'er done! 20 minutes here and there ain't gonna get it!

Hank

Just keep pluggin away at it and I think you will win that battle.
