Re: [MW:17167] HAZ hardness

Dear Experts
 
During welding& after welding the heat input generated in the weld area including haz. But the haz area cool rapidly than the weld area. so the hardness would be higher than that of weld metal.

Dear Hrushikesh,

It is due to the distortion of grain structure occurred during welding in the HAZ area due to heat transfer from the molten weld metal to the base metal.
