آليات الربط في لحام المونة والبرصمة للإسلاك المضفورة

Abstract

Galvanized steel stranded ropes ( 10.3 mm diameter ) were welded by brazing and
soldering , also stranded copper cables ( 9.5 mm diameter ) using Socket – Butt joint with
capillary gap between 50 – 100 um , and 2 mm butt gap . Welding was completed by torch
technique with commercial fluxes . The filler – metal alloy are copper – phosphors for brazing
and tin-lead eutectic for soldering . The bonding mechanisms are generally the same .
Bonding phase I will be created at the interface , while the intermediate phase II is the
remainder . Mechanisms are different in spreading , wetting and bonding strength
