Solder Wire Core
The solder wire core is an integrated flux in tubular soft solder, which transports both flux and metal. It simplifies handling.
Physicochemical Mechanism of Action
The core in the solder wire consists of a tubular soft solder with flux embedded in its inner groove. This flux helps transport auxiliary substances and metal to ensure an even melt distribution.
Metallurgical Relevance & Welding Risks
Using a cored solder wire improves the melting process, since it ensures a constant supply of auxiliary substances and metal. This prevents pore formation and raises the strength of the weld. If the flux is missing, uneven melt distribution and pores can occur, which hurts the toughness and reliability of the weld.
Workshop Practice & Instructions
Use cored solder wires for better melt quality. Make sure the flux is properly enclosed and not clogged or melted out. With pore formation problems, check the flux supply and the quality of the solder wire.
