Descriptions
|
KJF-620 is an Aluminate Basic agglomerated flux. Clean weld bead and easy slag detachability for thin plates with normal speed for flat and fillet welding . In case of thick plates with speed welding of lower than 40cm/min, slag detachability deems slightly difficult compared with normal circumstance. Having impact strength at 0°C the flux meets appropriate mechanical properties and is suitable for welding on structural steel and metal construction.
