K-600HT
Suitable welding positions
For hard facing (Hv550~700)
Hardfacing for wear plate and weld metal's hardness should be about Hv 550~700
Classifications
JIS Z 3326 : YF3B-C-600
Description
- It is designed for welding of metal to metal and underlying welding of hard-facing
- Typical applications include crane wheels, blower blades, bucket lips, dredge parts etc
- In order to minimize cracking, one should obey the preheat and interpass temperature
Polarity & shielding gas
- CO2: 100% CO2 (15~25 /min)
- DCEP (DC+)
