The present invention relates to a welding mask for protecting the eyes of a user from a strong welding light during welding. More particularly, the present invention relates to a welding mask which has a face protecting plate made of a transparent material to protect the face of a wearer from the heat and flame of welding and to enable the wearer to see a broad portion of the surrounding area of a welding point, and which has a light shielding part the light shielding rate of which is higher than that of said face protecting plate so as to block the strong welding light generated from the welding point. The welding mask consists of a head part to be worn on the head of a wearer and a face protecting plate installed at the front portion of said head part so as to cover the entire face of the wearer, wherein the face protecting plate is injection-molded with a transparent synthetic resin material so as to block harmful light and flame generated during welding, wherein a portion of said face protecting plate has a light shielding part formed thicker than the face protecting plate so as to have a light shielding rate higher than that of said face protecting plate.
