This paper presents the effect of the observation of micrograph of metallic crystal and hardness tests in the weld deposit metal and heat affect zone. The emphasis is placed on the changes of hardness and metallic crystal transformation due to the affect of welding current and preparing heat. As the welding current and a preparing heat rising, the changes of the metallic crystal in heat affect zone and weld deposit metal is deposit metal is dropped by welding current condition and preparing heat condition, but the change of hardness and metallic crystal in the basic metal is very small.
