Applications：
Mainly used in the welding for SUS316L stainless steel of urea tower, petrochemical equipment and other equipment as well as the same type of stainless steel structure.
Characteristics:
THA022 is rutile type stainless steel electrode with ultra-low carbon. Can be weld for all-position with AC or DC. It have excellent welding performance as good arc stiffness, little spatter, easy slag removal etc.
Attention:
1. The electrode must be re-dry by 320℃-350℃ for 1 hour before welding.
2. The rust, oil, water and other impurities of the weld area must be removed before welding.
3. DC+ is better than AC, lower heat input is suggested, the temperature of preheat and interpass keep under 150℃.
