Definition

1. Noun:

   • A single weld created by joining metals at an isolated point: A "spot-weld" refers to the individual, typically circular, fused joint produced by the spot welding process, where two metal surfaces are joined by applying heat and pressure at a specific, confined location.

2. Verb:

   • To join metal pieces by making a weld at a discrete point: To "spot-weld" means to create a weld by concentrating heat and pressure on a small, defined area, resulting in a series of separate, point-like welds rather than a continuous seam.

Usage Examples

• Noun:

  • The strength of the assembly depends on each individual spot-weld.
  • Inspect the spot-welds along the seam for any cracks.

• Verb:

  • The technician will spot-weld the brackets to the frame.
  • These pipes are only spotwelded, not continuously welded.

Advanced Usage

• Technical Context: In manufacturing, especially automotive and sheet metal work, "spot-weld" is a standard term for a fast, efficient joining method using specialized electrodes.
  • The robot arm is programmed to spot-weld the car body panels with precision.

Variants and Related Words

• Spot welding (n): The process or technique of creating spot-welds.

  • Spot welding is commonly used in assembly lines.

• Spot-welder (n): A machine or person that performs spot welding.

  • The spot-welder applied a series of perfect joints.

Synonyms

• Point weld (n): A less common synonym for a spot-weld.
• Weld (v): A general term; to spot-weld is a specific type of welding.

Related Phrases

• Resistance spot welding: The full technical name for the common spot-welding process, which uses electrical resistance to generate heat.
  • Resistance spot welding is ideal for joining thin metal sheets.
