    • The present invention provides a multi-layer electro gas arc welding method which is capable of preventing brittle crack propagation even though a brittle crack is generated. A welding device comprises: a first wire torch for feeding a first wire to weld a gap between welded materials of a steel plate; a second wire torch for feeding a second wire; and a welding main body connected to the first wire torch and the second wire torch. Provided is a multi-layer electro gas arc welding method comprising: a first molten metal forming step for forming a first molten metal by melting only a fist wire by using an arc formed by a first wire of an electrode wire torch; a climbing step for climbing the welding main body after melting a certain amount of the first wire; and a second molten metal forming step for forming a second molten metal by melting a second wire of a second wire torch with the first wire.

    • PURPOSE: A multi-electrode submerged arc welding apparatus is provided to prevent an arc at a rear side from being exposed to air when a flux is split, thereby restraining an unstable welding process. CONSTITUTION: A multi-electrode submerged arc welding apparatus includes multiple electrodes, and the electrodes comprise a first electrode (1), a second electrode (2), a third electrode (3), and a fourth electrode (4). The first and the second electrode are placed on a welding line for submerged arc welding in series. The third and the fourth electrode are placed after the second electrode, and are separated from the welding line. The apparatus is capable of additionally including a fifth electrode after the third and the fourth electrode. The apparatus is capable of additionally including the fifth electrode and a sixth electrode which are placed after the third and the fourth electrode and are separated from the welding line.
