Description and Applications

BLUECORE 71T is all position rutile cored wire for low risk medium carbon steel. It can be used for 100% CO2 or 80% Argon 20% CO2 gas mixture for shielding gas. The slag is easy to remove. The wire gives high deposition rate, consistency free from inclusion, porosity and x-ray soundness. This wire is also designed for single and multi pass and perform well over mild scale and normal rust. Application will be on heavy wall thickness structural steel works, pressure vessel, shipbuilding, automotive and construction industries.
