Product Description
Flux Cored welding Wire E71T-1C

AWS SPECIFICATION: AWS A5.20 ASME SFA-A5.20


Typical Applications:

• Pipeline

• Offshore structure

• Pressure vessel

• Structural parts of carbon steel and low alloy structural steel with tensile strength ≥
490 MPA is the most widely used

Features:

• E71T-1 flux core MIG wire GMAW (MIG) welding alloy
• Designed for welding heat-treatable base alloys
• Suitable for sustained elevated temperature service
• All positions, include vertical down welding
• Gray-white(post anodized) color

Welding Current: (DCEN) Straight Polarity

Welding Positions: H, F, V-up, O

Shielding Gas: 100% CO2

Performance Characteristics:

• E71T-1 is titanium oxide type CO2 gas shielded flux cored wire with excellent welding

performance and soft and stable arc.

• Small splash, easy slag removal, beautiful welding seam. Suitable for all
position of welding, the welding efficiency is high.

• The weld metal is treated with trace elements and has good low – temperature toughness, good
crack resistance and stable and reliable intrinsic quality.

Notice:

1. The flow rate of shield gas should be within 20L-25L/min

2. The wire extension should be 15mm-25mm.

3. The surfaces to be welded must be cleaned away from impurities of oil contamination, rust, moisture, and so on.

4. The welding conditions mentioned above are for reference only and it is better to do a welding procedure qualification according to the project before putting it into formal welding
