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? http://postimg.org/image/qzydzw2vx/

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, Reply to drawoh For the symmetry tolerance i am referring to the iso standard 2768 http://www.nan-long.com/Metal%20Steel%20Technology%20Summary/ISO%202768-2%20Geometrical%20tolerances.htm Reply to CheckerHater [highlight #A40000]Using positional tolerances...

Hi, I have two questions on GD&T in ISO, the questions is imbedded in the pictures below: http://s3.postimg.org/arf4wvvpf/image.jpg http://s22.postimg.org/gf9sezlkh/image.jpg Kindly Paul

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...

The drawing http://postimg.org/image/dk8d545s5/2e86fecc/

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. http://s10.postimg.org/n2xw32pvt/image.jpg

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 ???

Hi I have an aluminium detail with some helicoil holes (M6, M8, M10 and M12). The material is EN 5052 T5, which is an aluminium alloy which has Rp0,2 on 60 MPa, which isn't that much. The bolts is 8,8 What tightening torque should i use? There r tabels for 8,8 screws, but the strength of the...

About the picture i posted; i guess you can't use angularity to define a cone? (wishful thinking) Could you use the position tolerance to define the cone?; i have only seen the position tolerance for hole center and flat surfaces About pmarc's comment: ee fig. 8-26 in Y14.5-2009 - this...

Thank you for your replies; you wanted more context so I have uploaded another picture: http://s27.postimg.org/gql2o2en7/image.jpg Kindly Paul

Hi, First of all i am using ISO. I have noticed that the meaning of circular runouts change if the arrow is not pendicular to the surface, can someone explain that to me? My main question is that i want to put a tolerance to the cone below (the thing which are brown)...

Hi i am going to make a pressure vessel for 3 bar, and I haven't been working with pipes before. I have found a pipe and a cover, see the picture below. My question is how do I join the items together; seems hard since the cover and the pipe has the same diameter. Do I chamfer the profile and...
