Hi,

As you seen on drawing we will do fillet weld at this ring.The material grade 42CrMo4 ( SAE 4140 ).

I searched on internet it must be apply preheating which degree nearly 316ᵒ C before welding and after welding it must be apply heat thearetment ( 590  ᵒC-600  ᵒC ) and than cool down at room temperature.
