CONFORMANCES AND APPROVALS:

• AWS A5.29, E120T5-K4C H4
• AWS A5.29M, E831T5-K4C H4

• ASME SFA 5.29, E120T5-K4C H4

• Maintaining a proper welding procedure - including pre-heat and interpass temperatures - may be critical
depending on the type and thickness of steel being welded.

• See Above: This information was determined by welding using 100% CO2 shielding gas with a flow rate between 35-50 cfh (17-24 l/min).

STORAGE

FEATURES AND BENEFITS

• Very high tensile strength deposit
• Basic slag system
• Very high weld ductility and low-temperature toughness
• Large diameter wires with high deposition rates

• Low diffusible hydrogen weld deposit

• Suitable for use with many ~120 KSI (830 MPa) Quench & Tempered (Q&T) and High-Strength Low-Alloy (HSLA) Steels

• Very effective at removing impurities to produce a high-quality weld deposit

• Helps minimize the risk of cracking in critical applications and repairs

• Helps increase travel speeds and productivity

• Minimizes the risk of hydrogen-induced cracking
