AI and this job
AI exposure: how much of this job’s work AI tools can do or help with, based on national research. It is not a forecast of job loss.
Lower exposure12 of 100
The index averages three national research measures, each shown as a percentile of all jobs:
- AIOE 14
- Language-model AIOE 15
- GPTs-are-GPTs 6
Observed AI use today: Little or none (Anthropic Economic Index)
AI exposure for this job is lower, and observed AI use is little or none. AI tools could help with reading drawings and planning the order of work. They do not touch the hands-on fitting, aligning, and welding. Massachusetts is projected to lose jobs in this field (-13.4%), partly because federal projections say collaborative robots let the same crew produce more.
Likely to change
- Reviewing drawings and planning work sequences
- Figuring material needs from blueprints
Still relies on people
- Positioning, fitting, and welding parts by hand
- Checking pieces with squares and tape measures
What federal projections say
“Productivity change - share decreases as collaborative robotics increase efficiency, allowing more output to be produced with the same amount of labor.”
