Spot-welding
Definition:
Spot-welding is a method used in metalworking where two pieces of metal are joined together by applying heat and pressure at small points, creating a strong connection. This is done by using an electric current that heats the metal, making it melt slightly at the spots where the two pieces touch.
Usage Instructions:
- Part of Speech: Noun - How to Use in a Sentence: "The car manufacturer uses spot-welding to assemble the body of the vehicle."
Example:
"The engineers decided to use spot-welding to connect the metal panels of the new machine because it is quick and efficient."
Advanced Usage:
In industrial settings, spot-welding is often used for making products like cars, appliances, and electronics because it is a fast way to join metal without needing additional materials like glue or rivets.
Word Variants:
- Spot-weld (Verb): To perform the action of spot-welding.
- Example: "The technician will spot-weld the components together." - Spot-welder (Noun): A machine or tool used to perform spot-welding.
- Example: "The spot-welder is essential for the production line."
Different Meanings:
In general English, "spot" can also refer to a small mark or stain, and "weld" refers to the process of joining two pieces of metal together. However, when combined as "spot-welding," it specifically refers to the welding technique described above.
Synonyms:
- Resistance welding (a broader term that includes spot-welding) - Laser welding (another type of welding technique)
Idioms and Phrasal Verbs:
While there are no specific idioms or phrasal verbs that directly relate to "spot-welding," you may encounter phrases in metalworking or engineering contexts. For example: - "Join forces" can metaphorically describe coming together like pieces of metal in welding.
Summary:
Spot-welding is a crucial technique in metalworking used to join pieces of metal together at specific points with heat and pressure. It is fast and efficient, making it popular in manufacturing.
