Morphology
The compound is directly composed of 'spot' (a particular/small location) + 'welding' (joining metal), so a learner who knows both words can infer it means welding performed at small specific points. Technical details (e.g., electric current) are specialized, but the basic process is transparently derivable and has clear cross-linguistic parallels, making it understandable to B1 learners.
Etymology
Spot welding comes from the simple image of making small spots of melted metal that join two sheets using heat and pressure. So, spot means a small point and welding means joining metal, and the expression means 'joining metal at a few small points'.
