With a Trade Pay Score of 57 (C), structural welders in St. Louis are mid-tier — neither standout strong nor materially weak. The combination earns a reasonable nominal wage but is dragged down by either flatter wage growth, a higher cost of living that erodes purchasing power, or thinner employment depth.
