fe 360, fe 430, fe 510 which deforms less in phase of welding?

[Paulì_zx]

Hey, guys.
I have a question to ask your experience.
According to you between fe 360, fe 430 and fe 510 what is the structural material that if subjected to welding deforms less and creates less problems of tension?

Hello and thank you

 

[gerod]

quite generic question!
the answer could be:
depends on what kind of sadness you do, how you do the welding, if you can do a détente, who does the sading, how the lembi are prepared.
I'd say you should be more precise.
Thank you.

I'm sorry, but in this case I feel more comfortable with the gerod response...

but the answer from the president is correct and perfectly relevant;
..a generic answer.

Sorry if I was a little "laconic", but I was interested in highlighting the fact that the question tended to put together different and often opposite problems.

then if we want to deepen, always available.

Surely in the welding phase the carbon percentage plays a fundamental role for a quality operation. . .that is translated into poor words less carbon there is and less problems there are.
this obviously at equal treatment, preparation, etc.
This is because the presence of carbon favours, due to the strong thermal cycles that occur in welding, structural modifications on the material, with the appearance of fragile structures and strongly tensioned (typically martensitic).
I would therefore recommend that you use fe360, even if all the steels mentioned above guarantee good welding results.

I would say that these 3 types of steel are quite similar as regards deformations and tensions after welding. at least in the workshop I have never heard complaints about it by welders, unlike for example when weld the 304l / 316l. maybe tomorrow I try to ask more specific.

 

[Pastorman75]

deformations as a result of welding are caused by:

1) for both autogen and heterogeneous welding, surface tensions inside the material and already present and released (from the same material) in the welding point. Many merchant laminates are laminated or worse drawn and surface tensions are not negligible. welding, especially if with continuous and long traits, creates a sort of localized "distension" with release of tensions and relative deformation to compensation. in this optical it seems better to use laminated with lower internal tensions, such as hot rolled in materials with less carbon s235 (fe360) instead of s355 (fe510)

2) in the case of heterogeneous welding, tensions caused by withdrawal of the material made that from liquid passes to solid with relative withdrawal. based on this important is the intake material that are often low-retire alloys.

these are general considerations and both the geometry of the piece and the welding cycle, affect not little the deformation of the welded artifact.

right, we must not neglect the process of obtaining the material. perhaps more than the material itself, a lamination, extrusion, tempering, pallination (or pallination? boh?!), can affect more than chemistry on post welding deformations. as well as the geometry of the pieces.

excuse a question, if the input material is different from the one to join, is it still about brazing? or is it common practice to call everything "saving"?

 

[Pastorman75]

if the melting temperature of the two metals is analogous, then we talk about "heterogenous" welding (divesi materials).
if the melting temperature of the intake metal is considerably less, then we talk about "brasation".

in a few words, in the "brasation" the intake material does not bind with that base

 

[Messerschmitt]

in this optical it seems better to use laminated with lower internal tensions, such as hot rolled in materials with less carbon s235 (fe360) instead of s355 (fe510)

for which applications the internal tensions are so harmful to make the s235 prefer to the s355, despite the mechanical characteristics of much lower?

in the post is contained the answer. Just read.
