Metal finishing, plating and coating machine operators

Sensors can measure the plating. Running the tanks safely is still a person's job.

Checking plating thickness is mostly out of AI's reach. It barely touches seven of the eight tasks, including mixing plating solutions and running electroplating and cleaning equipment.

What they actually do (and what else they get called)

Metal finishing, plating and coating machine operators monitor and operate equipment which finishes, plates and coats metal articles or parts in order to give them improved resistance to corrosion and abrasion, for decorative purposes, or to impart electrical or magnetic properties. Tasks include - (a) operating and monitoring equipment which cleans metal articles in preparation for electroplating, galvanizing, enamelling or similar processes; (b) operating and monitoring electroplating equipment; (c) operating and monitoring hot-dip equipment used to coat iron and steel products; (d) operating and monitoring machines which automatically coat wire with non-ferrous metal; (e) operating and monitoring equipment used to spray molten metal or other substances onto metal products to provide a protective or decorative coating or to build up worn or damaged surfaces; (f) operating and monitoring equipment used to impart a rust-resistant finish to metal articles by treating them with chemicals and heating them; (g) checking proper thickness of plating using micrometers, callipers or other devices, recording data and writing production logs; (h) preparing and mixing metallizing solutions according to formulas or specifications.

80 / 100

Mostly holds up against AI

AI can take a few chores off your plate, but most of the day is still yours.

Not the odds you keep your job. It's how much of the everyday work still needs a person, out of 100.

The ILO's official verdict: Not Exposed

148 of 427 for holding up against AI

Why this score?

The ILO rated each of this job's 8 tasks for how much of it AI could do. They average 20.5 out of 100, so it holds up at 100 − 20.5 = 79.5.

That's the whole sum. No black box, no secret sauce: you can check it against the ILO's study. ILO group “Not Exposed”: None of this job's tasks scored high enough to count.

Pinch of salt: this number is probably too rosy

It only asks what AI software could do, and this job is 67 out of 100 hands-on. A chatbot can't do that part. A robot might, one day, and nobody measures how close that is.

Meet your two rivals

They're not the same machine. AI software can only reach the parts of a job done on a screen or in words. A chatbot can't climb a ladder. A robot might, one day, if it doesn't fall off.

The AI

Lives in a screen. Never had to fix a boiler.

Threat level: Low

25 could do without you

It could take over very little of the work on its own. It could help with 58 of 100.

The robot

The wildcard. Has hands, still working out stairs.

How much it matters here: Higher

67 how hands-on

Most of this job needs hands, a body or turning up. That's robot territory, and nobody measures how far robots have got well enough to give you a number. We won't make one up.

So could a robot do the physical part?

More fine handwork, and more time in cramped or awkward spots, than a typical hands-on job. That is exactly what machines find hardest: they do best in tidy, predictable places.

Robots hate fiddly work in awkward spaces. On that measure, this job scores 40 out of 100. The higher it is, the longer the robot waits.

The small print

They aren't a robot score, and nothing on this page is. Nobody measures how far robots have got well enough to put a number on it. These are the closest thing we have: how hands-on the job is, and how much fiddly, cramped work it takes, which is what Frey and Osborne found hardest for machines.

The job, task by task

Every job is really a bundle of tasks. Here's this one unpacked, with how much of each AI could do, out of 100. The score is the average, and averages can hide a lot.

AI's favourite task here scores 28, against an average of 21. The bigger the gap, the more lopsided the job: some of it wide open to AI, some of it barely touched.

Sidekick or replacement?

A tool that makes you faster is a very different thing from one that does the task while you watch. Jobs and Skills Australia measured the two separately, which is handy.

Sidekick wins, by 34 points.

So, should metal finishing and plating operators be worried?

Short answer: not much. Some of the chores will change, and good riddance.

No. The most exposed task is checking plating thickness and writing logs, rated Low; running plating, galvanising and coating lines rates Very Low. Automated lines and sensors help, but handling chemicals and equipment stays hands-on.

Worth remembering: we score tasks, not jobs. When AI takes on a task, the job usually reshuffles around it rather than vanishing.
