Welding Problem
Welding Problem
(OP)
Hi All,
I'm have no luck in creating/welding two rods together. They form the base of my fan guard, previously discussed.
What I have, refer attached file, is a circular ring of 6mm dia. steel rod and in the centre to give the item strength, is a cross piece also made from 6mm steel rod.
I have tried several ways to create the weld with no luck. Can anyone offer a solution to the problem.
Best Rgds,

I thought I did have parts, one the outer ring and one the centre brace. I see that the centre brace should have been in three pieces but I still cannot weld the ends t the outer ring.
I'll try again and see how I go.

Attached are the ipt files for the main support and the outer ring. Just thinking about this, could it be that I have a flat surface just touching in one very small spot on the ring, maybe I shoule extend the support just a little to give more surface to the ring.
See what you think.

RE: Welding Problem
I rarely use weldments, I can't justify the time spent on modelling the welds. I just use weld symbols and general notes. Weight generally isn't that critical, if it is I will add a conservative amount to my total. The only time I would use them is if I needed it for presentation (which is not often).
RE: Welding Problem
I'm very new to Inventor and am still feeling my way around all the different aspects of the program. I obtained a book written by Thom Tremblay and went through the various exercises and am putting the experience gained there to my own products.

RE: Welding Problem
When I opened your parts with the assembly file the positions must have moved so I can't see what you were trying to do. However I assume you have a face against a tangent or a tangent against a tangent. Either way Inventor will have trouble applying a weld when it doesn't have a clear termination. Try slightly notching your rod to match the contour of your hoop and see if you have better luck applying the welds.
RE: Welding Problem
Yes that's what I thought. I'll give that a try.
Thanks for your comments and time.
Just in passing, there is a raft of books on the market and I'm not sure which to get next so can you recommend anything that will help develop my understanding and techniques.

RE: Welding Problem
The part names do not match the names referrenced by the assembly do not match - do not use Windows to rename files, they are all hyper-linked.
I would not "notch" the anything I saw in the assembly.
Split Face on the round hoop would give the face to add Groove Weld and then Fillet Weld.
But by the time you zoom out on this you would not be able to see the weld beads - so it looks like overkill for this assembly. I realize you are just trying to learn the software....

However there are probably better specific tutorials and white papers out there.
Don't go for any ATC training courses, most of the time you wont get shown the practical skills needed. Customised training is better or just work through tutorials and white papers specific to the work you are doing at the time.
Research master sketches, multi-body master parts, derived parts, linked parameters, etc. These will help you build intelligence into the basic skills you learn from the books.

RE: Welding Problem
This way you don't have to notch or split faces..
RE: Welding Problem
Thanks for all your help and advice all taken on board. It does get overwhelming when there is so much information out there that forums like this one are invaluable to novices like myself.
Keep up the good work and thanks again.

RE: Welding Problem
Don't throw out unsubstantiated claims. I teach for an ATC. If there is an ATC instructor to avoid you should cite the location and name of the instructor to avoid.
When I am doing a class for a single company I can customize to their product line. If the class is attended by several companies then there is no choice but to make it general-purpose. In any case the general basics have to be covered.
RE: Welding Problem
"The general basics have to be covered..."
Actually they don't or they are being taught in the wrong way. I have been running training in the workplace for years and there are many flaws with conventional training. They don't need to be taught how to create a sweep or how to create a lid for a box they will never build. What they need is training in how to apply Inventor to they products they design.
Take a simple example like handrails and stanchions. The standard training may cover sweeps, thicken, revolve, etc, but do you think a new user who has taken the training could complete a standard guard rail on a platform in 30mins? No, they can't.
Inventor training needs to be in the context of application. General-purpose, standard techniques is a complete waste of time and money.
I have seen the course material and data sets so you can't argue they are by any means practical.. My advice is solely based on working in the industry, as a drafter, designer and engineer. If you think the ATC training is useful then perhaps you should go back to working in the industry and you might gain perspective on the needs of the end users.
RE: Welding Problem
There you go generalizing again.
I worked in industry for 15 years - many in various production positions, 8 as a machinist, R&D, Industrial Engineering.... I am very confident in my competency from through the entire process from art-to-part.
I use my own course material.

RE: Welding Problem
I am not attacking you personally, if your teaching is somehow special, then congratulations on leading the revolution. However, based on my experience and people I have talked to over the years (both in the workplace and online) shows that the standard ATC training courses are both a waste of time and money. This is my advice only and comes with no warranty, no documentation, take it or leave it. If you don't believe my advice is accurate, don't take it on board, simple. Ask around you will hear the same thing.
I also hold my AICP and CSWSP-FEA but I don't quote them because those exams are too simple to be a true test of anything.
RE: Welding Problem
I understand that you both hold very strong views for both sides of the argument but I ask you, is this the right forum to air you views.
We all must, first and foremost deal with the initial question and not be lead astray by personal views of this kind.
If needs be start a new post "ATC or not ATC" and see what the general consensus is. I understand that it will not change either minds on the subject but, it will give you both an area to express your deep held points of view on the subject.
Very Best Rgds,
Dave R.
RE: Welding Problem
Really the choice is up to the individual, if you feel that the training will be of benefit to you, then by all means give it a go and make up your mind.
I only offer my personal opinion and preference, as I always do on these types of forums. I can't speak for rollupswx's training, only what I have seen and heard.
Many application engineers were horrible designers so they went into teaching, this is not always the case, some are brilliant users and designers.
I guess you have to treat it on a case by case basis but you know what my stand point is, based on my experience only.
I am not going to hash it out further but if you are interested check out some of the comments on other forums.

Run a search, come up with your own opinion.
Still my recommendation is always tutorials, white papers, customized training, or take a job with a company that has proficient Inventor users and trainers (but don't forget to read in your own time).
