The present invention relates to an automatic moving and welding apparatus for a dome box of a liquefied natural gas (LNG) carrier. According to the present invention, an automatic moving and welding apparatus for a welded material (10) with a protruding step part (12) comprises: a driving means (20) having a driving wheel (22) formed on a bottom surface and a clamping wheel (24) formed on a side surface on a frame (21); a rail means (30) connecting the frame (21) of the faced driving means (20) with a support (31) and including a rail unit (32) on the support (31); a carriage means (40) coupling a carriage (41) to the rail unit (32) of the rail means (30) and having an LM guide (42) formed on one side of the carriage (41); and a torch means (50) mounting a holder (51) on the LM guide (42) of the carriage means (40) and having a torch (52) formed on the holder (51). Accordingly, plasma welding is applied to a dome box of an LNG carrier, thereby providing an effect capable of enhancing welding productivity. Moreover, provided is an effect of preventing musculoskeletal diseases of a welder through partial energy saving due to automatic driving and welding.

    본 발명은 돌출턱부(12)를 지닌 피용접재(10)에 대한 자동주행 용접장치에 있어서: 프레임(21) 상에서 저면의 주행휠(22)을 측면의 클램핑휠(24)을 지니는 주행수단(20); 상기 주행수단(20)의 대향하는 프레임(21)을 지지대(31)로 연결하고, 지지대(31) 상에 레일부(32)를 지니는 레일수단(30); 상기 레일수단(30)의 레일부(32)에 캐리지(41)를 결합하고, 캐리지(41)의 일측으로 LM가이드(42)를 지니는 캐리지수단(40); 및 상기 캐리지수단(40)의 LM가이드(42)에 홀더(51)를 장착하고, 홀더(51) 상에 토치(52)를 지니는 토치수단(50);을 포함하여 이루어지는 것을 특징으로 한다. 이에 따라, 액화천연가스운반선의 돔박스에 플라즈마 용접을 적용하여 용접 생산성을 향상시키고, 자동주행 용접에 의한 부분적 생력화를 통해 용접사의 근골격계 질환을 예방하는 효과가 있다.
