Question

1. name three ways, other than bolting, of connecting a workpiece lead to the base metal.

Explanation:

These are common mechanical/industrial methods for establishing a secure electrical or physical connection between a workpiece lead and base metal without bolts, used in applications like welding or electrical grounding.

Answer:

1. Welding (fusion or spot welding the lead directly to the base metal)
2. Clamping (using a dedicated mechanical clamp to hold the lead to the base metal)
3. Soldering (using a molten solder alloy to bond the lead to the base metal, for conductive connections)
