FLASH WELDING Meaning and
Definition
-
Flash welding is a specialized welding process that involves the joining of metal parts through the use of intense heat generated by an electric arc. It is a solid-state welding technique in which two metal workpieces are rapidly heated and brought into contact under high pressure, resulting in a strong and continuous fusion.
In flash welding, the two workpieces to be joined are positioned parallel to each other with their ends in contact. An electric current is then passed through the workpieces, creating an arc between them. The intense heat produced by the arc causes the metal surfaces to melt, creating a molten pool. As the current continues to flow, the molten metal is expelled from the joint, creating a flash of light and sparks. The heat and pressure generated during this process cause the molten surfaces to be rapidly forced together.
Flash welding is commonly used for joining components in the automotive, aerospace, and construction industries, as well as in manufacturing electrical components. It offers several advantages, including high welding speeds, minimal distortion, and a strong metallurgical bond. The process is particularly effective for welding dissimilar metals, such as steel and aluminum, as well as for joining metals of varying thicknesses.
Overall, flash welding is a versatile and efficient welding technique that enables the secure and efficient joining of metal parts through the application of intense heat and pressure.

Etymology of FLASH WELDING
The etymology of the word "flash welding" can be traced back to two main components: "flash" and "welding".
1. "Flash": The term "flash" in this context refers to a sudden burst or emission of light or heat. It comes from the Old English word "flæsc", which originally meant "floating bark" or "driftwood". Over time, it evolved to mean a sudden burst or flame-like appearance. This sense of "flash" was then applied to welding, describing the brief, intense burst of light and heat generated during the process.
2. "Welding": The word "welding" originates from the Middle English verb "weld", derived from the Old English word "weldan", meaning "to control", "to govern", or "to wield". Originally, "weld" referred to the act of forging metal by heating and hammering it together.
