Membrane welding process of inflatable tent

I. Material Preparation and Inspection

1. Membrane Material Quality: Ensure that the membrane material used is of qualified quality, free from damage or contamination. Materials such as PVC double-sided coated fabric, which offer high strength, waterproofing, and UV resistance, are typically selected.
   Note: Material specifications must comply with project requirements.

2. Welding Electrodes: Inspect the welding electrodes to ensure they are intact and their surfaces are clean and free of impurities. This guarantees stability and welding quality during the process.

II. Pre-Welding Preparation

1. Surface Cleaning: Use cleaning agents and damp cloths to wipe the surfaces of the tent material and reinforcement material, ensuring welding points are free of debris and dust. This step is critical for ensuring welding quality.

2. Material Compatibility: Verify that the membrane material and reinforcement material to be welded are of the same type to prevent detachment caused by material mismatch.

III. Welding Process

1. Trimming Reinforcement Material: Use scissors or blades to trim the reinforcement material to the appropriate length and width. It should be slightly wider than the tent material to ensure full coverage of the welding point.

2. Marking Welding Positions: Use a ruler and pencil to mark welding positions on the tent material. Align and secure the reinforcement material in place. This ensures precision and consistency in welding.

3. Uniform Welding:

   • Maintain even contact between the electrodes and tent material to avoid burning or perforation.
   • Adjust the welding temperature according to the membrane material’s properties and the welder’s specifications. Excessively high or low temperatures will compromise welding results.
   • Maintain a steady welding speed. Moving too quickly or slowly may lead to weak adhesion or burning.
