RE: [MW:13103] what is the root cause for copper crack in saw welding ?

 Hi MPK,
 
 
It's a form of solidification cracking caused  due to localized segregation of low melting elements. Copper is one of the elements which tends to form so, for C.S and high strength and medium strength low alloy steels.
 
Please see the reference below.
 
Thanks.
