Abstract：The forming reasons of the skin blowhole in welding gas cylinder steel HP295 are analyzed. It is shown that the degree of superheat of molten steel and the deoxidation alloying are main factors for the formation of skin blowhole. Then some measures for preventing and controlling them are proposed.
