Morphology
The meaning is directly compositional: 'butt' denotes an end-to-end join and 'weld' denotes a fused metal joint, so their combination describes exactly a weld made end-to-end. This is a regular noun–noun compound following transparent modifier + head patterns and, despite being technical, a B1 learner who knows both constituents can reliably infer the meaning.
Etymology
Butt weld comes from a simple picture: the butt is the 'end' of each metal piece and a weld is a join made with heat, so the name describes two ends placed together and joined. That's why a butt weld means a joint made by welding two pieces 'end to end'.
