| Welding: |
| weldability limited |
— welding is possible in the process of heating up to temp. 100−120? C and further thermal treatment |
| konovalivka |
in order to obtain quality welded joints, it is necessary to perform additional operations: during welding heating up to temp. 200−300°C, heat treatment (annealing) after welding. |
| Welded without any restrictions |
— welding is carried out without further heat treatment and pre-heating. |
