- Applications
- Welding of 50kgf/mm² class high tensile strength steel of ships, bridges structure and pressure vessels.
- Characteristics
-
- - Excellent crack resistance even in the welding of difficult to weld steels.
- - W 7016 is a low hydrogen type electrode with excellent crack resistance.
- Notes on Usage
-
- - Remove dirts such as oil and scale from the groove.
- - Dry the electrodes at 300~350℃ for 30~60 minutes before use.
- - Keep the arc as short as possible.
- - Take the backstep method or strike the arc on a small steel plate prepared to prevent blowholes at the arc starting.
