no limits | Welding is performed without heating and without subsequent heat treatment | |
Boundedly welded | Welding is possible with heating up to 100–120 °C and subsequent heat treatment | |
Difficult to weld | For obtaining quality welded joints, additional operations are required: heating up to 200–300 °C for welding, heat treatment after welding — annealing | |
Not applicable for welded structures |
