Method for Manufacturing a wire wrapped airtight that contains the elements of filling, wrapped tight thread obtained from dichoprocedimiento ManufacturingProcedure of Arc Welding using the welding wire wrapped airtight and obtained with this procedure.

摘要

A process for the production of metal tubes containing fillers, in particular a sealed solder lining line, a sealed solder lining, which creates a gas shielded atmosphere with a controlled content, To avoid or minimize the entry of gaseous atmospheric impurities into these feed lines, especially nitro, hydrogen and humidity. The sealing yarn obtained in this way is basically free of gaseous nitroglycerin,It is best to be completely free of gaseous nitrates, water vapor, and gaseous hydrogen that can be used in arc welding procedures, especially TIG, MIG, MAG, and adhesive processes. The nitrogen content of solder produced by arc welding is less than 60 ppm, preferably less than 50 ppm, and / or diffusive hydrogen content is less than 5 ppm, preferably less than 4 ppm. The gas protective atmosphere used is composed of a, he, CO2, O2 or a mixture thereof, which can be realized with the second priority of atmospheric air. The N2 content in the seal liner line is less than 100 ppm.
