Can C40E Be Welded???

Can C40E Be Welded???

Can C40E Be Welded???

(OP)
As the title says, can EN10083 C40E be welded?

If so will the welding process revert the material strength back from that of Quench and Tempered to normalised?

As it stands We need the material to have a Fty approx 330 and the normaised condition gives Fty approx 290.

Is there any simple means to be able to tell if a certain grade of steel can be welded?

Cheers, Andy

RE: Can C40E Be Welded???

Andy,

The question "can grade X of steel be welded" is too simplistic.  Almost anything can be welded by one process or another, but there are significant limitations in terms of usable properties, degree of preparation required, etc.  In general, steels that have already been quenched and tempered are not suitable for arc welding (GMAW/MIG, GTAW/TIG, etc.) due to their extreme susceptibility to cracking and reduced mechanical properties, notably fracture toughness.  I suggest you perform a keyword search using the term "carbon equivalent" and welding in order to understand the scope of the problem.
