The pressurized dual seam [testing] method was mentioned earlier in connection with the double-wedge thermal seam method. The air channel that results between the double seam is inflated to approximately 30 lb/in² for 100 to 200 ft. If no drop in pressure occurs, the seam is acceptable; ,,,  2, record 1, English, - dual%20seaming

The hot wedge or hot knife method consists of an electrically heated resistance element in the shape of a blade that is passed between the two sheets to be sealed. As it melts the surfaces, roller pressure is applied. An interesting variation is the dual-hot-wedge method, which forms two parallel seams with an unbonded space between them. This space is subsequently pressurized with air and any lowering of pressure signifies a leak in the seam  2, record 1, English, - dual%20seaming
