## Scope

Japan. The Industrial Safety and Health Order lists the welding of boilers and first-class pressure vessels as licensed work, excluding welding by automatic welding machines, certain pipe circumferential joints and parts under compressive stress only; the Act says employers may not put anyone but a licence holder on such work, and that no one else may do it. The quoted item reads the same in every version on e-Gov from 1 June 2017; its last amendment is earlier and could not be read there. Boilers and pressure vessels only.

## What this means

In Japan, hand welding on pressure equipment is reserved for licensed people, and the law already draws the line at automatic machines.

## What it does not show yet

Boilers and pressure vessels in one country; it does not cover structural or pipeline repair work.

## How to verify it yourself

Open the Industrial Safety and Health Order on e-Gov, go to Article 20, and find 「自動溶接機による溶接」.
