THA022 (E316L-16)

THA022 (E316L-16) 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.

Features

• Molybdenum-added extra-low carbon formulation for superior pitting and intergranular corrosion resistance
• AC and DCEP dual-purpose operation with smooth all-position welding capability
• Stable arc performance with minimal spatter and self-peeling slag
• Exceptional resistance to organic acids, mineral acids, and marine environments
• Aesthetic weld bead appearance requiring minimal post-weld cleanup
  

Typical Applications

• Cross-country oil, gas, and water pipeline girth seam welding
• Open-root pass pipe welding and pressure piping
• Storage tank, vessel, and structural steel fabrication
• Field repair and maintenance on unprepared steel
• Shipbuilding and offshore structure construction
  

Welding Positions

• PA / PB / PC / PD / PE / PF 
  

WARNING

• The electrodes must be re-dried at 320°C–350°C for 1 hour prior to welding.
• Rust, oil, moisture, and other contaminants must be removed from the weld zone before welding.
• DC⁺ is preferred to AC, with lower heat input suggested. Preheat and interpass temperatures should be kept below 150°C.
