Hi,
I am making a welded structure with ISO corners, and need to set tolerance between the ISO corners. I look at earlier project and there have no tolerances at all, beside the general ISO tolerances. If I look at the standard for a general container it say L= +0-10 mm W= +0 -5 h= + -5.
But...
Hi
I about to design a container. The container has a double door, I know how to seal a single door, but not a double door, my problem is the area where the two door met, see the picture below. Do anyone have a suggestion how to do this sealing arrangement?

HI
you can find the tolerances here:
http://www.sicamtubi.net/PDF/ENG/QUADRI/10.pdf
For BEAM 60x60 cross section
Max outside dimensioner
60->60.6
60,6+60,6+8=129.2
Hence
60,6x129.2
For BEAM 140X70X4 cross section
Min outside dimensioner
140-> 138.6
70 ->69.3
Max thickness:
4*4.1= 4.4
This...
Hi,
Two beams one 60x60 and another 60x60 beam with a welded 8 mm sheet shall be placed inside a 500mm long 140x70x4 beam, see the attached picture. The material for all beams is S355J2H. I wonder if it will be a good fit. When I am checking the tolerances (EN 10210), I can see a scenario where...
Hi
Thanks for your replies,

For the symmetry tolerance i am referring to the iso standard 2768

Hi,
I have two questions on GD&T in ISO, the questions is imbedded

Hi,
I have a problem when I am looking after rare sizes of sheet metals, pipes and round bars. I am in an engineering firm and generally gives job to different local workshops. Since I am not buying the steel myself, there are not any reason for the companies who sell steel to help me, and I...
It think it is hard to avoid those standards since most European companies tend to have ISO 13920 and ISO 2768 in the drawing header.
About overall dimension. That would mean that 3 extra dimensions would be added on the drawing I posted on 22 Mar 14 12:30. But those dimensions would only...
Pmarc, so it is 10+/-0.5 because for parallelism?
Another question
In clause 4.3 it say , the following table 3 apply to both overall dimensions of a weldment, a welding assembly, or a welded structure, and also for sections for which dimensions are indicated.
i am a bit unsure who i shall...
Ok, i have attached 2 pictures one is the drawing and the other one is who the item ended up after manufacturing. Can you say based on Clause 7 that the manufacturer has done an error here?
i hope this isn't a stupid question.

Well, i base my design on earlier drawings that someone else has done and those drawings had no dimensions and aparently that has worked, to change that i need to make an argument and that is why i asked about how i shall interpret ISO 13920 when there are surfaces who are flush with no Linear...
But i think that should be covered by ISO_13920 i am just not sure if i interpret it rigth, in the table for linear dimensions it only cover the distance from 2 to 30, not from 0 to 2? But of course i get angular dimension, straightness, flatness and parallelism from ISO 13920.
It is possible to make a welding drawing of the item in the picture without adding any measurements, (if you have drawings on details 1 to 4), because the items is aligning with the edges of item 1. So what I wonder is who I shall interpret the general tolerance concerning distance in this case...
Ok, if we look at page 7 on the following document
http://www.collycomponents.se/wp-content/uploads/2013/05/Helicoil-Plus.pdf
In the first row in the table it says for M12 15.5 Nm on 1st screwing-on; but what is the rows below about? 1st screwing-off, min and 5th screwing-off, min ???
