HOT KNIFE SEAM [5 records]

Subject field(s)
  • Engineering Tests and Reliability
  • Joints and Connections (Construction)
  • Waterproofing (Construction)
OBS

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/in[upperscript 2] for 100 to 200 ft. If no drop in pressure occurs, the seam is acceptable; ...

OBS

The hot wedge or hot knife method consists of an electronically 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.

OBS

Contrôle d'étanchéité de soudure sur [géo]membrane bitumineuse au moyen d'une cloche à vide.

OBS

Double soudure: Modalité d'assemblage comportant la réalisation simultanée de deux joints parallèles, effectués en soudure automatique et séparés par une zone non soudée. Ce canal central sert généralement à faire des tests d'étanchéité du joint, sous pression

OBS

There are a number of thermal [seaming] methods that can be used on thermoplastic geomembrane materials.... 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.

OBS

Soudure thermique: Mode d'assemblage avec pression dans lequel les surfaces sont amollies par la chaleur. Celle-ci génère sur les deux surfaces à souder une température élevée provoquant une fusion partielle des matériaux à souder. Cette chaleur peut être apportée par une lame métallique, par un jet d'air, des ultrasons ou un champ électrique haute fréquence.

OBS

Soudure : Résultat de l'opération de soudage. (Longtemps utilisé comme synonyme de "soudage" (...), ce terme est maintenant réservé exclusivement pour désigner le cordon de soudure exécuté par un procédé de soudage quelconque.)
