Waterproof mechanical coil welding and coil closing, sealing
Waterproof mechanical coil welding:
For large-surface waterproof mechanical coil welding, automatic welding machines should be used as much as possible. Before the welding machine is used for test welding, after the welding quality requirements are met, the square surface welding is carried out. At the same time, the automatic welding machine should pre-position the special gasket between the two waterproof mechanical coils at the beginning of the welding seam, and then For welding, the gasket should be placed in the correct direction.
Coil closing, sealing:
The coiled material should be handled in time, and the aluminum alloy bead is used to close and seal. There shall be no unprocessed closing before the daily work, and it shall be protected in special circumstances; the T-shaped joint of the waterproof mechanical coil shall be specially treated, and the joint shall be treated with a scraper or TPO base metal to ensure the welding of the coil. quality.
