Why coding matters so much
The biggest factor in a welder’s pay is coding — passing certified weld tests to recognised standards (for example ASME or ISO) for specific processes and positions. Coded welders in petrochemical, mining and power-generation environments earn far more than general fabrication welders.
High-paying welding sectors
- Petrochemical & refineries — Sasol, refineries, shutdown work.
- Power generation — Eskom stations and boiler work.
- Mining — structural and plant maintenance.
- Pipeline & pressure vessel — coded pipe welding.
Processes and pay
Specialising in TIG and coded pipe welding generally pays more than basic MIG or arc welding. Shutdown and contract work can pay premium day rates but is less stable than permanent employment.
