(1) The overlap width of weld bead is 80-100 mm;
the natural folds of plane and vertical surfaces are 5%-8%;
the reserved expansion is 3%-5%; and the residual edge material is 2%-5%.
 
2. The working temperature of hot-melt welding is 280~300 C,
the speed of 2~3m/min is welding, and the form of welding is double pass.
 
3. Repair methods for damaged parts, materials with the same cutting specifications,
hot-melt adhesive and polyethylene resin seal.
