The present invention is to combine the welding surface 20 to the hard hat 10 to achieve the purpose of face and eyesight protection and head protection at the same time, freely up and down in the state in which the welding surface 20 is coupled to the hard hat 10 It is to provide a hard hat 10 for attaching the welding surface 20 to be rotated. That is, the present invention, in the conventional welding surface 20 for mounting helmet 10, the coupling means 30 is coupled to the coupling means 23 of the welding surface 20 in the position raised from the lower end of the helmet 10 to the top ) Is configured high from the lower end of the hard hat 10, the drip tray 40 having the same width as the drip groove 16 formed around the hard hat 10 in front of the hard hat 10 is integrally configured without a visor. , Between the main body 11 and the headband 13 in the front of the hard hat 10 is characterized in that the safety glasses 50 made of a transparent reinforced plastic configured to slide up and down, according to the present invention weld surface ( When the welding surface 20 is coupled to the hard hat 10, the center of rotation of the welding surface 20 is increased, and the welding surface 20 is removed from the hard hat 10 by eliminating the part caught by the welding surface 20 when the welding surface 20 is rotated. Rotating freely greatly improves operation reliability and ease of use. Do not use a connector which can prevent accidents such as electric shocks, can significantly reduce manufacturing costs and manufacturing airborne, it can expect a large number of effects that can more significantly reduce the fatigue of the eyes by safety glasses (50).본 발명은 용접면(20)을 안전모(10)에 결합시켜 안면 및 시력 보호와 머리 보호의 목적을 동시에 달성할 수 있도록 하고, 용접면(20)을 안전모(10)에 결합한 상태에서 상하로 자유롭게 회동시킬 수 있도록 한 용접면(20) 부착용 안전모(10)를 제공코자 하는 것이다.즉, 본 발명은 통상의 용접면(20) 부착용 안전모(10)에 있어서, 용접면(20)의 결합수단(23)이 안전모(10)의 하단부에서 상부로 올라간 위치에서 결합되도록 결합구(30)가 안전모(10) 하단부에서부터 높게 구성되고, 안전모(10)의 전방에 안전모(10) 둘레에 형성되는 물
