説明
特徴
LKE-9016-G is a low hydrogen electrode for the welding of 620 N/mm² grade high tensile steel. With good mechanical property and X-ray test.
アプリケーション
It is suitable for welding of shipbuilding, machine fabrication, offshore structure, pressure vessel, high pressure pipe and base metals are forging cast iron, structural steel, steel pipe for heat transfer, pressure vessel, alloy steel, ASTM A202/486 Gr90/736 Gr3, etc..
使用上の注意
1.Preheat at 80°C is sometime required according to base metal or its thickness.
2.Do not exceed the range of recommended because over heat input might decrease the impact value.
3.Keep the arc as short as possible.
4.Take the back-step method at the arc starting to prevent blowholes.
