technical aid welding

Good evening to all


How do I dimensional welding?? ?and where can I find the yield values of the materials to calculate the admissible sigma? ? ?


Hi.
Thank you.

Hello, David,
I would say that welds the size according to former cnr 10011 or better eurocode 3 uni en 1993-1-8:2005 and uni en 1993-1-9:2005

However on the net there are good notes for university students about it, which are worthy of note. search and find "welded unions".

the eligible sigma always find them in the regulations and however you will find the formulas and what to use effectively as values (we always talk about tensile strength load)

attention that for some types of welding is due to fatigue testing.

attention that some types of welding are not the class ii, so nondestructive controls and certifications are required.

attention to intake materials and junction types: full penetration or corner cord.

well studied regulations, made a clear mirror on how to move. if it is something repetitive made the excel sheet where you enter your basic data and check automatically. if you use inventor, you have special welding calculation modules. after reading the regulations, check in the inventor's guide to understand how it handles checks and compares methods.

should be all good work

Thank you very much

I use inventor but at the moment I have never used the part dedicated to the calculation of welds could you give me a tip? ?
I started reading everything about Eurocode 3 speech turns out to be interesting and I have to say that I didn't think it was so wide.

for the part of inventor there is the special module ... you need to search in the help and check here in the forum that we have already talked about. It's a long time I don't stop anymore, but I remember it's in the section where there are: bolted joints, springs, welding etc.
There is a panel where you insert geometric features, it seems to me that it makes you select the bodies as well and creates a welding and in the panel there are sigma values, indicate the loads and he makes you check.

check better because I don't remember exactly.

Ok, graz mille!!!
