街外れの小さな鉄工所。ワンマン社長のもとで毎日あくせく働く男たち。鉄を溶かしたりくっつけたり、ロボットの足場を作ったり、感電したり、火傷したり。そしてそれを支えたい娘と、寄り添う妻。世知辛いけどあったかい、溶接デイズへようこそ。
A small steelworks on the outskirts of town. Men toil away every day under an autocratic boss. Melting and gluing iron, building scaffolding for robots, getting electrocuted, getting burned. And a daughter who wants to support them, and a wife who stands by them. Welcome to Welding Days, a cruel but warm world.
