Title: AUTOMATIC WELDING SYSTEM FOR CORRUGATED MEMBRANE SHEET OF MEMBRANE TYPE LIQUEFIED-GAS CARGO HOLD, STRUCTURE FOR GUIDING AND FIXING AUTOMATIC WELDING APPARATUS FOR CORRUGATED MEMBRANE SHEET OF MEMBRANE TYPE LIQUEFIED-GAS CARGO HOLD, AND STRUCTURE FOR GUIDING AUTOMATIC WELDING APPARATUS FOR CORRUGATED MEMBRANE SHEET OF MEMBRANE TYPE LIQUEFIED-GAS CARGO HOLD
Abstract:
The present invention relates to an automatic welding system for a corrugated membrane sheet of a membrane type liquefied-gas cargo hold, a structure for guiding and fixing an automatic welding apparatus for a corrugated membrane sheet of a membrane type liquefied-gas cargo hold, and a structure for guiding an automatic welding apparatus for a corrugated membrane sheet of a membrane type liquefied-gas cargo hold. When a corrugated membrane sheet is welded, a cross-anchor strip having a fixing groove is installed on a portion where longitudinal and lateral anchor strips, which are attached to the upper surface of a heat insulating panel on which the corrugated membrane sheet is mounted, cross each other, which makes it possible to install a welding guide that supports the automatic welding apparatus and guides a movement of the automatic welding apparatus using the fixing groove, thereby stably performing automatic welding on the corrugated membrane sheet.
