Storage Packet For Welding Flux Comprising a Sandwich Structure of the Polymer/Metal Film Type Method For a Storage of a Welding Flux in Such a Packet and Method For Arc Welding Using a Welding Flux Stored in Such a Packet

摘要

The invention relates to a storage packet for welding flux, in the form of a bag (1) containing welding flux (5) and with at least one layer of thermo-welded polymer (3a, 3b) and at least one metal film (2), superimposed one on the other and a structure with flexible deformable walls forming said bag (1), characterized in that said bag (1) is hermetically sealed and pressured within the bag is less than atmospheric pressure. The invention further relates to a method for storage of welding flux in such packet.
