              unmoderated group sci.engr.joining.welding
Newsgroup lines:
sci.engr.joining.misc	Joining of materials for manufacture & repair.
sci.engr.joining.welding	Welding of materials for manufacture & repair.
Votes must be received by 23:59:59 UTC, 27 Dec 1996.
This vote is being conducted by a neutral third party.  Direct
questions about the proposed group to the proponent.  Do not
distribute this CFV or the information contained in it in any form

RATIONALE: sci.engr.joining.misc
Materials joining plays an integral role in the fabrication,
manufacturing, and repair of virtually all structures and devices.  These
operations are a significant source of added value and have a major impact
on reliability and performance.  The technologies associated with successful
joining of materials span a wide range of engineering and scientific
disciplines.  Advances in materials, design, manufacturing and industrial
engineering, process control and automation all interact to increase the
complexity of each joining application.  A newsgroup dedicated to discussion
of joining-related issues will greatly facilitate communication between
scientists, engineers, and manufacturers with common challenges.  It would
also provide a platform for cross-disciplinary exchange on joining-related
issues.  The newsgroup, sci.engr.joining.misc, is proposed, not as a catchall
group, but as a rational starting point for joining related groups under the
sci.engr.joining hierarchy.
RATIONALE: sci.engr.joining.welding
Welding is one of the most common joining processes utilized in manufacturing
and fabrication today.  The International Institute of Welding/Institut de
Soudure currently identifies over 140 separate welding processes and allied
technologies, ranging from arc welding for thick section steel fabrication to
the wire bonding processes used in electronics manufacture. These operations
are a significant source of added value and have a major impact on system
reliability and performance.  The technologies associated with successful
welding span a wide range of engineering and scientific disciplines.
Advances in materials, design, manufacturing and industrial engineering,
process control and automation all interact to increase the complexity of each
joining application.  A recent Deja News search revealed over 4,000 posts on
welding-related topics across USENET.  This indicates more than sufficient
interest to create a welding newsgroup.  A newsgroup dedicated to discussion
of welding topics will greatly facilitate communication between scientists,
engineers, and manufacturers with common challenges.  It would also provide a
platform for cross-disciplinary exchange on welding-related issues.   The
newsgroup sci.engr.joining.welding is proposed for the exchange of scientific
information and technical discussion of welding issues.
CHARTER: sci.engr.joining.misc

Subject: Sulfer - Materials handling.
From: Darryl Fitzgerald
Date: Mon, 16 Dec 1996 11:39:13 -0800
Please reply / share any information / knowledge you have in regards to
the handling of sulfur ( in powder form ).
I am looking at the problem of discharging sulfur from a conventional
(existing) railway wagon.  The wagon has no bottom discharge facilities
and tipping the entire wagon is not an option (only the wagon's side is
removeable!)
Is pnuematic conveying by vacuum suction an option ? or does this pose
serious risks in respect to static build-up and consequent increased risk
of sulfur fires?
Thanks in advance for your reply.

I agree.  The Machinery's Handbook is one of the best.  I even keep a
copy at home.  I know you said you're looking for larger books, but
there are some 'pocket-size' books I've found handy to have around for
"quick and dirty" stuff and you can't beat the prices.
Carr Lane's "Handy Multipliers and Trigonometry Tables for Engineers"
has a good list of conversion factors and trig formulas even if we
don't need the trig tables much anymore.  Even the cheap-o scientific
calculators have 'em built in.  The book is usually free from local
tooling distributors.
The other 2 are from the Electrical Apparatus Service Association
(EASA).  They are the "Mechanical Reference Handbook," and the
"Electrical Engineering Pocket Handbook."  Motor rewind shops give
them away and write it off for advertising.

From: david.rouse@engineers.com (David Rouse)
Date: Tue, 17 Dec 1996 15:09:00 GMT
Have you thought of friction? Maybe you can use a disk the width
of heating zone inside a tube just small enough to allow for
interference (from the tube being welded) due to thermal expansion and
just spin it. By chossing the right materials, its possible to produce
lots of heat with mimimal wear. Advantadge: probalbly real cheap to
make. Drawback: I could see problems with uneven heating.

:Metric is actually British Standard Pipe thread and isn't either metric or

Is there such a thing as a metric tapered thread pipe fitting?
What do they use in europe for basic houshold piping?
As an aside, unless its quite a rough vacuum I would suspect its
not a thread seal fitting at all. Possably some sort of flare or

Dear Collective:
    Does anyone out there know of a good program that incorporates
material data for engineering?  i.e. a soft periodic table or other
materials type data base.  I've got one from "The Big Blue Disk" from a
while back, but it's very basic, and some of the information is dead
wrong.  I would prefer freeware or low cost shareware, but if it's good
enough perhaps the company would purchase it.

You probably need to talk to someone who has made the microstation to
PROE conversion.
Comparisons between most solids packages are hard. We just converted to
PROE from Ideas and CADDS 5. Some things on PROE are really good. It has
good data integrity and it is robust for changing parts in assemblys and
modifications to parts. But some of the geometry creation can be a real
pain. Of course, where I work, we are creating very large parts with
high length/thickness aspect ratios and a large number of parts. For a
small firm, I think it would be a fairly good package. Just beware of
ellipses and splines and small angles and fillets. These can cause some
real heartburn. The drafting package could also be better, but it is
adequate, especially if you don't have a hardnose checking staff.
Ellipses are not too bad, but offsets to ellipses come in as splines,
and splines have some problems.

Subject: iRMX OS - Where to buy?
From: Ray Minich <73444.1755@CompuServe.COM>
Date: 16 Dec 1996 21:34:33 GMT
My interest in the iRMX kernel has been piqued by the recent 
press.  Where can I buy a copy of the system, how does one get 
technical specs and info on the system?  Does it work under/with 
MSDOS-6.22?, Win 3.1, 3.11, 95?
Any and all advice on this software would be greatly appreciated.
Thanks and regards,

Glenn Thomson bashed its head on a keyboard, resulting in:
: I'd like to know what locomotive engineers and stationary engineers call 
: themselves in your part of Ontario, then.
As in the rest of Canada, "locomotive engineers" call themselves
"hoggers."  As a P.Eng with the railway, my father always went out of his
way to correct people that called them engineers by telling them it was
pronounced differently (ingin-eers or something) but they call themselves
hoggers.
Whether it is common practice or not, still doesn't make it right.  The
PEO (and other organizations) should make more of an effort to dissuade
the improper use of the term "engineer."

Greetings folks.  I'm trying to track down the propeties of
aluminum alloy 7005.  All of the materials books I have looked
into do not mention it.  Is it relativly(sp?) new?  
I actually need it for my thesis of a bicycle that is constructed
from 7005.  I'm not sure what treatment the frame has but if 
somebody has any information at all I would appreciate it.

I have used Microstation and AutoCAD as well as PRO/E, although I only
used Microstation briefly. The similarity between the 2 is that both have
a similar interface (UNIX-like, even on non-UNIX platforms). However,
Microstation / AutoCAD and similar programs are primarily for 2-D
drafting, with some 3-D features thrown in. I think Microstation's 3D
abilities exceed AutoCAD's by far, though. PRO/E on the other hand is a
parametric 3-D modelling software, with very capable 2-D drafting
abilities (although it lacks some of the bells & whistles of other 2-D CAD
programs). In PRO/E, everything is built around the 3-D model. Once the
model is done, the 2-D drawing almost generates itself; this is one of the
things that really impressed me about PRO/E. Modelling in PRO/E is alot
different that drawing the same part in 2-D. In PRO/E, you model much as
you might actually machine the part.
If your company does alot of work w/ mechanical systems and would like the
option of easily integrating CAM w/ your CAD system, PRO/E may be the way
to go. PRO/E can definitely be a big timesaver - I love it. For primarily
2-D drafting work where few major design changes are made, a 2-D CAD
program would probably do the job just as well as PRO/E for less money,
though.

          I don't know if a general statement can be made about this.  All 
states prefer that work be under supervision of a P.E.  Many states allow for 
work not under a P.E.  to qualify, but require additional evidence and review. 
Some potential candidates have posted that their states do not allow work not 
under a P.E., but no P.E. has confirmed that here.

          No.

Subject: Sands fluidity and driving conditions.
From: q9421754@helios.usq.edu.au (Alan B Holland)
Date: 17 Dec 1996 16:44:12 +1000
A Problem I have Come across while driving in remote areas of Australia
where ther is no sealed roads is getting bogged in sand. The question I
want to ask is how does temperature effect sands fluidity. In the morning
when the sand is cooler say 20 Deg C, it is good to dive on, but as the
day goes on and sand temp gets to say 50-60 Deg C, it boggs very easily.
Is this due to elctrostatic forces perhaps?, Expanded air?.
I am just guessing and was wondering if anyone had done any work with
anything simular.
Thanks,
Alan

	It should work with abrasive waterjet, which is high pressure waterjet
with fine abrasive injected into the waterstream.
	With waterjet (without abrasive), at 50 mm thick, it may work only with
very high pressure since wood fibres are tough and not brittle.
	Good luck.				John Cheung, PhD
