KAC-818W

Type of coating: Iron powder low hydrogen type
It is ideal for welding in ASTM A588, A242, JIS G3114 SAM steel and bare steel structures

It is suitable for 540N/mm2 grade weather resistant steel.
It provides good weldability, mechanical properties, X-ray quality welds and crack resistance.
Weld metal has great weather resistance due to Cu, Ni and Cr contents.
It is ideal for welding in ASTM A588, A242, JIS G3114 SAM steel and bare steel structures

Clean up the contaminations on the steel before welding.
Dry the electrodes at 300~350°C for 60 minutes before welding.
Keep arc as short as possible. Take the back step method to prevent porosity at arc start and re-start. (Please refer to Appendix A).
The preheat temperature for thick plate (thickness > 25mm) or rigid joints is 90~120°C.

It is ideal for welding in ASTM A588, A242, JIS G3114 SAM steel and bare steel structures.
