Welding
ISO 4063 process numbers
In short
111, 135, 141…: the process written on a WPS, a certificate or a symbol.
Arc welding
| No. | Process | Acronym |
|---|---|---|
| 111 | Covered electrode | MMA · SMAW |
| 114 | Self-shielded flux-cored wire | FCAW-S |
| 121 | Submerged arc, solid wire | SAW |
| 131 | MIG solid wire, inert gas | MIG · GMAW |
| 132 | MIG flux-cored wire | FCAW |
| 133 | MIG metal-cored wire | MCAW |
| 135 | MAG solid wire, active gas | MAG · GMAW |
| 136 | MAG flux-cored wire | FCAW |
| 138 | MAG metal-cored wire | MCAW |
| 141 | TIG with solid filler | TIG · GTAW |
| 142 | Autogenous TIG | TIG |
| 143 | TIG with cored filler | TIG |
| 15 | Plasma arc | PAW |
The process is an essential variable: a WPS or certificate in 135 does not cover 136.
