<p>A cross point makes a welding work difficult to be performed for modules in a marine plant, and more particularly, a weld failure easily occurs as a pipe for a facility is too long to secure an argon space even though a purge should be made for nonferrous metal. Moreover, a space is too small to make purge for TIG welding, thereby also hindering the welding work. In order to solve the problems explained above, the present invention provides a welding method for the cross modules of the marine plant comprises a step of preparing; a step of transferring a first transferred material; a step of transferring a second transferred material; a step of transferring a material for welding; a step of welding; and a step of removing after welding. The welding method for the cross module of the marine plant is provided to transfer the first and second materials to the facility pipe or to the end of the facility by driving two motors in the forward or backward direction, thereby facilitating the welding work by easily transferring the materials required for welding.</p> |
