Deskripsi
Karakteristik:
LKE-8018-W2 is an electrode for the welding of 550 N/mm2 grade high tensile steel. With good atmospheric corrosion resistance, good X-ray soundness and good crack resistance. The weld metal contains Cu, Ni and Cr.
Aplikasi:
It is suitable for welding of high tensile steel such as SMA570W/P,ASTM A350/350M,etc.
Catatan tentang Penggunaan:
1.Dry the electrodes at 350-400°C for 60 minutes before use.
2.Take the back-step method at the arc starting to prevent blowholes.
3.Keep the arc as short as possible.
4.While applying in plate with high restraint (such as the plates is thicker than 25mm) ,preheat at 80-100°C is recommended.
5.Do not exceed the range of recommended because over heat input might decrease the impact value.
