Attention & Precautions
1Use Direct Current Electrode Positive (DCEP) welding (wire connected to anode).
2Utilize CO2 as shielding gas with a purity > 99.9% and a flow rate of 20-25L/min.
3For multi-pass welding, maintain the interpass temperature between 150°C to 200°C.
4To prevent pores, thoroughly remove grease and rust from the base metal surface before welding.
5Storage: Wire is moisture-resistant treated. Use promptly after opening; do not expose unused wire to air for extended periods.
6Due to the softer nature of the wire, avoid over-tightening the wire feeding device pressure roller.
Frequently Asked Questions
What are the primary applications for AWS E71T-1C welding wire?
AWS E71T-1C is primarily used for welding low-carbon steel and 490MPa grade high-strength structural steels.
Can this flux-cored wire be used for vertical or overhead welding?
Yes, it is a titanium slag system wire designed for all-position welding, including flat, horizontal, vertical, and overhead positions.
What shielding gas is required for E71T-1C?
It requires 100% CO2 shielding gas with a purity level of at least 99.9% for optimal results.
What is the recommended polarity for this welding wire?
The wire should be operated using Direct Current Electrode Positive (DCEP), where the welding wire is connected to the positive terminal.
How should I store the flux-cored wire once the package is opened?
The wire should be used as soon as possible after opening to prevent moisture absorption. Avoid leaving exposed wire in the air for long periods.
What is the impact toughness of this wire at low temperatures?
The wire demonstrates excellent low-temperature toughness, with a typical impact value of 128J at -20°C.
