Description |
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 |
