dc.description.abstract	This paper presents the effects of TIG direct current (DC) on the hardness of mild steel samples coated with stainless steel. The coating was undertaken using TIG welding using stainless steel welding rods. The hardness of the coated samples was analyzed using a Digital Rockwell hardness Tester. The hardness test was carried out across the coated samples from the substrate to the coating region. The data obtained when hardness was measured is presented and discussed in this article. The relationship between DC welding current and hardness is also discussed. From the results, the hardness of the coated samples increased from the substrate towards the coating surface. It was also shown that hardness and DC current of the TIG system exhibit an inverse relationship.	en_US
