1. An inflatable boat processing method, comprising:
cutting material following an inflatable boat sample, wherein cutting material following the inflatable boat sample comprises cutting the material into a plurality of boat-side material pieces and a boat bottom material piece;
connecting the boat-side material pieces, wherein connecting the boat-side material pieces comprises connecting adjacent edges of the boat-side material pieces in an overlapped mode along a shape of a boat-side body, wherein the to-be-connected portions of two of the boat-side material pieces are hot-melted first, and then the hot-melted portions are overlapped and tightly pressed, thereby obtaining a boat-side body, wherein a first connecting end and a second connecting end are formed on an inner side edge and an outer side edge of the boat-side body in its width direction;
connecting the boat-side body with the boat bottom material piece, wherein connecting the boat-side body with the boat bottom material piece comprises connecting the first connecting end of the boat-side body with the boat bottom material piece in an overlapped mode, tightly pressing, and then bonding by ultrasonic bonding;
sealing the boat-side body, wherein sealing the boat-side body comprises connecting the inner side edge of the first connecting end and the outer side edge of the second connecting end of the boat-side body in an overlapped mode, wherein the contact surfaces of the first connecting end and the second connecting end are hot-melted first, and then the hot-melted contact surfaces of the first connecting end and the second connecting end are overlapped and tightly pressed, thereby obtaining the boat-side body having a closed annular air-storage chamber; and
obtaining an inflatable boat.
