Definition:
Flash welding is a process used to join two pieces of metal together. It involves creating a quick electric arc between the two pieces, which generates enough heat to melt the edges of the metals. When they melt and touch, they fuse together, forming a strong joint. This technique is often used for joining segments of metal pipes.
In more advanced discussions, you might encounter phrases like: - "The efficiency of flash welding makes it a preferred method in industrial applications." - "Flash welding requires careful control of the electric arc to ensure a proper joint without damaging the materials."
In general English usage, "flash" can refer to something that happens very quickly or suddenly, like a flash of light. However, in the context of "flash welding," it specifically refers to the quick process of welding.
