Boilermakers

Boilermaking remains largely a hands-on trade. Workers install bricks, valves, and heavy plates by hand, and inspect and weld boilers using torches and tools. ^[1] For example, the BLS notes boilermakers must “test and inspect boiler systems… clean vats with scrapers… and replace or repair broken valves… using hand and power tools, gas torches, and welding equipment” ^[1]. Today, there are few fully automated solutions for these tasks.

One research project built a flexible robotic welder to apply corrosion-resistant cladding inside boiler tubes ^[2], showing that automation is possible in controlled settings. Also, modern AI (like image-recognition systems) could help inspections. A BLS review observes that AI now excels at tasks such as image recognition and robotic manipulation, which could in theory assist defect detection ^[1].

But in practice, these AI tools are mostly experimental or used as aids, not replacements. Importantly, a 2022 BLS study found “little support” in the data for a sudden wave of job loss from robots and AI ^[1]. In short, while some high-tech inspection machines and advanced sensors are emerging, most boilermaker chores (installing bricks, fitting parts, welding in tight spaces) still require human skill and judgment.

Whether firms quickly adopt AI in boilermaking depends on cost and practicality. Building a robot for each new boiler job is very expensive compared to hiring a skilled worker. Boilermaker work is often done on-site, one unit at a time, so the Union-scale labor cost (roughly $\$70k$–$\$80k$ yearly) can actually be lower than the multi-hundred-thousand dollar price of custom robotic systems.

A recent BLS analysis notes that many occupations haven’t seen major declines despite AI – one reason is the high investment and complexity involved ^[1]. Companies also factor in safety and regulation: boilers hold pressurized steam, so any automated system must be extremely reliable before managers trust it.
