Morphology
The meaning 'a localized weld made at a single point' is directly and compositionally derived from 'spot' (a small, particular location) + 'weld' (a joint formed by fusing metal). This straightforward noun+noun compounding is productive in English and mirrors patterns in other languages, so a B1 learner who knows both constituents will readily infer the MWE meaning.
Etymology
Spot weld comes from the simple picture of a small spot of melted metal that welds two pieces of metal together. Because this happens at one tiny 'point', the term now means a single, local weld.
