Solder - Wikipedia
Solder (/ ˈ s oʊ l d ər /, / ˈ s ɒ l d ər / or in North America / ˈ s ɒ d ər /) is a fusible metal alloy used to create a permanent bond between metal workpieces. Solder is melted in order to adhere to and connect the pieces after cooling, which requires that an alloy suitable for use as solder have a lower melting point than the pieces being joined.
Expansion of MX-MIG process as Pure Argon Gas Shielded Welding Method - for Carbon Steel
It used to be considered that pure argon (Ar) was inapplicable to metal inert gas (MIG) welding using steel wire. However, the newly developed process called "MX-MIG," which involves the use of a special welding wire made by Kobe Steel, makes it easily applicable.
METALLURGY FOR INSPECTION PERSONNEL
metallurgy is performed by addition of fluxes (CaO, CaF 2 and others) into the ladle and stirring the steel together with the slag, absorbing sulfur. In the production of high quality steel the operation of vacuum treatment in ladle is widely used.

solid-liquid phase diagrams: tin and lead
6/8/2020· This page explains the relationship between the cooling curves for liquid mixtures of tin and lead, and the resulting phase diagram. It also offers a simple introduction to the idea of a eutectic mixture. Important: This page is only really designed to be an introduction to the topic suitable for courses for 16-18 year olds such as UK A level chemistry.

What is Fusion Welding? - TWI
Fusion welding is a process that uses heat to join or fuse two or more materials by heating them to melting point. The process may or may not require the use a filler material. External appliion of pressure is not required for fusion welding processes, except for resistance welding, where substantial contact pressure is required during welding for sound joining.

Fusible plug - Wikipedia
This hole is sealed with a metal of low melting point that flows away if a pre-determined, high temperature is reached. The initial use of the fusible plug was as a safety precaution against low water levels in steam engine boilers , but later appliions extended its use to other closed vessels, such as air conditioning systems and tanks for transporting corrosive or liquefied petroleum gasses.
