SPOT WELD Meaning and
Definition
-
Spot weld, noun:
A spot weld refers to a type of highly-efficient welding technique used to join two or more metal objects together at specific points or "spots" through the application of heat and pressure. In spot welding, the metal pieces to be joined are placed between two electrode tips (usually made of copper alloy) and an electric current is passed through them. This flow of electric current creates resistance and consequently generates heat, causing the metal pieces to melt and fuse together.
The primary objective of spot welding is to create strong, durable, and permanent joints that can withstand various mechanical stresses. It is commonly used in the automotive, aerospace, and manufacturing industries for joining metal sheets, panels, or components. Spot welding is particularly suitable for joining thin sheets of metal, as it can effectively produce localized and high-intensity heat without damaging the surrounding areas.
A spot weld possesses certain characteristics that make it distinct from other welding techniques. Firstly, it is a fast process with welds being completed within milliseconds. Secondly, it eliminates the need for additional material such as filler rods, making it a cost-effective welding technique. Lastly, spot welds typically result in a small heat-affected zone, minimizing the chances of distortion or damage to the surrounding material.
Overall, spot welding is a widely-used welding method known for its speed, efficiency, and strength, making it a crucial process in many industries where metal joining is required.

Etymology of SPOT WELD
The word "spot weld" originates from English and is composed of two separate terms.
1. Spot: The word "spot" is derived from the Old English word "spott", which means a "small mark or stain". It has been used since the 14th century to refer to a specific place or location. In the context of welding, "spot" refers to a small area where two pieces of metal are joined together.
2. Weld: The term "weld" comes from the Middle English word "welden" or "wielden", which means "to become united". It has Germanic origins and can be traced back to the Old Norse word "velda", meaning "to weld" or "to hot-press". Welding involves the process of joining two pieces of metal together through the application of heat and pressure.
