Corresponding with AWS A5.29 E81T1-Ni1

 

 

 

Introduction: It is a kind of gas-shielded flux-cored welding wire for low temperature steel and low-alloy steel. JQ.YJ551Ni-1 is a kind of titania type CO2 gas-shielded flux-cored welding wire. It has excellent welding performance, soft and stable arc, fewer spatters, good slag detachability and beautiful appearance of weld. Suitable for downhand welding and horizontal welding. All-position welding. It has high welding efficiency. The weld metal has been given toughening treatment by microelements, so it has excellent low temperature toughness above -40°C and good crack-resistance.

 

 

 

 

 

Uses: Used for welding structures made of low temperature steel and low-alloy structural steel. Widely used for welding some key structures like shipbuilding, mechanical manufacture, pressure vessels, storage tanks, petroleum machinery, chemical machinery, ocean structures, etc.

We specialize in producing flux cored wire, our R&D center works closely with the professional experts and professors from different universitis and national research institutes. Our manufacture facility owns the advanced production equipment, up -to-dated inspection/measurement instrument and the perfect evaluation and quality control systems, we have ISO 9001:2000 certificate.We have 18 production lines with the capacity of 50,000tons per year. Our E71T-1 FCW performs very low spattering, high effective vertical welding, very stable arc and fast welding rate. The diffusible hydrogen content in the deposited metal reaches 3.5ml/100g, which significant avoid the cold cracking and porosity. We are the only FCW supplier in China has 3YH5 certification. We are also the biggest and best quality supplier in China for E71T-GS and E71T-11 self-shielding FCW products.main goods have been certificated by CCS,ABS,DNV,LR,GL,BV,NK,KR,RINA,RS. the ten ship classification society,and we really do alibaba for eleven years.
