quale cad per gestire benece the saldature?

[chessippeo]

What can be the most suitable cad for handling welds on complex shape models?
I am using inventor for modeling a motorcycle, with excellent results regarding axiemi also complex (for example the engine), but with considerable difficulty in the case of welded assemblies. For example, in the case of the fork, consisting of several shells of sheet printed and then welded, it completely refuses to create 3d cords even on completely simple areas.
Is there something more specific on the market, which is better in welds, keeping goodness in the management of assemblies?
thanks in advance for the answers

I have no experience about it, so my are just general indications.
you could try analog cads like solidworks, or see if more evolved cads like cad, they can be soddifacient.

Edge money with the latest releases manages well the welding cords even quite complex. in my work I am of daily use.

However, a colleague I create (ex pro/e) is even better in this case, but I never had a chance to see it at work.

to understand: Why models the 3d cords? I do a lot of mechanical mixed carpentry and welds are very important, but we manage everything via notes.
solidworks works with 3d cords but also with "cosmetic" cords in the model, but I never use them and I can't tell you whether they are reliable or not.

on a motorcycle frame I don't think they need to draw them in 3d, always that they do not serve for fem analysis, but for personal experience designing machinery of a certain stazza with cords from z=15, 20 , 25 and often also 30-40 on thick plates from 50-80-100-150 mm, I find without so much trouble to have on certain structures 350-400 kg in welding cords for which of some

quoto. You can imagine the miles of welding on a ship, I can't imagine shaping the cords.
I only add them in the case of some renders of details otherwise, as King says, annotations and away.

I agree with tequila: I use little, but I am useful above all to evaluate the encumbrances and couplings with other components. when I call them, there's something that "fuges"

Of course, in your case, maybe the situation changes!

to respond to chessippeo: I used them (very lightly) both on solidedge v18, and on pro/e wf3... let's say that for the use I make, I did not notice particular differences of effectiveness and speed! Perhaps with pro/e the package is wider, but I repeat, I do not use it in a pushed way, and we are still talking about quite old version of the software mentioned.

Hi!

on a ship surely represent all welds is very complex, but how do you evaluate the weight that is added to the structure? I understand that you do not look at the gram, so if one leaves the sandwich or the brioche on the deck of the ship this does not sink, but as you rightly say, with km of soldering, some tons of weight will go to sum up.

the "old" said to add 4% of the weight of the structure in question to "take to the wind". It is clear that in particular cases, having to dimension the cord, if you know the section and then the weight.
It is also true that in the joint the plates are cyanphritis and therefore "allightened" compensating in part, the increase induced by the cord.

the "old" they said well, I also used 3-4% when with the 2d I got the handled weight of the individual obsitics and the error on small structures of 5, 6 tons was on the order of 100-150 kg

 

[Parametric_Ozzy]

I agree with all that in general on the management of welding it is better to use cosmetics and annotation rather than to model them, except for the rare cases where I have to do fem checks or analyze better ingombs, said this confirmation that I create has an excellent management of the same and for the goodness of great assemblies I believe that there is not even to discuss...

please limit yourself to technical comments, avoiding promotional comments.

It will be as you say, but after the episode of the long curve sampling I prefer to check in person rather than trusting general validity claims, which then maybe are not confirmed by the facts.

the "old" said to add 4% of the weight of the structure in question to "take to the wind".

my experience, so feel right to deny. ships have very repetitive structures. on board you have some "models" such as motor foundations, crates, life zones and proravia of the collision wallpaper. for each "zone" there is a percentage to be added to consider the weight of welds. after a few blocks and proper wind the shooting of this percentage, it is amazing how it can be very precise also for very different ships.

normally the percentage goes from a 2.5% in the motor zone to a 3.5% in dense areas of thin wallpapers such as the anticollision zones, countercane etc.
for smaller ships can also reach 4%, but personally I have never exceeded 3.5%.

separate speech are the wooden boats/ships or fiberglass. It is known that wood electrodes tend to produce irregular cords and fig welds (fiberglass inert gas) deposit material often irregularly. in those cases the percentages to be taken are different.

 

[Parametric_Ozzy]

I do not know what discussion you refer to because I read the forum by now infrequently, in any case if it were as you say then you should check in person with the facts all the discussions, as always it is made controversy where there is no need, I am of the warning that a person can say what he wants especially in a "free" forum, is then to the person who asks the question to make his checks of the case and draw his conclusions.

and according to your experience, in these cases what percentages would you recommend to adopt?
You never know I'm back on plastic boats. . .

I refer to this debate:
http://www.cad3d.it/forum1/showthread.php?35325-pattern-lungo-curvain which you hesitate to say that I create solved the problem very well, and where it touched me and another user to find out that he was unable. If that time you said I created that thing and it wasn't like that, now maybe I'll also be justified by the fact that I create it's the best cad to handle the big assemblies. Obviously you are free to say what you want, as other users are equally free to comment and argue.

I as a moderator have the obligation to keep the discussion on the technical track, and if I consider it appropriate I intervene with the prerogatives I have available.

I prefer not to comment, the videos are to be seen are made on purpose, I repeat that if you have it with me for anything it is enough to say openly, we must not necessarily agree, in fact I will always say what I want if I respect the regulation, I also saw the discussion so much here has become a classic. :biggrin:
