Morphology

spot-weld = spot + weld (transparent) = spot + weld

The meaning is a straightforward compound 'spot' + 'weld' referring to an individual weld at a spot; learners can derive the sense from the components.

Etymology

Spot-weld combines spot meaning 'small point' and weld meaning 'to join metal by heat', so a spot-weld is a small join made at a single point to hold metal parts together.
