1 Rev. 04. Supercored 71H. FLUX CORED ARC welding consumables . FOR welding OF Mild & 490 Mpa CLASS. HIGH TENSILE STEEL. HYUNDAI welding CO., LTD. Supercored 71H. v Specification AWS E71T1-C1A4-CS1. (AWS E491T1-C1A4-CS1). (AWS E71T-1C/ -9C/ -9C J). EN ISO 17632-A T 42 4 P C1 1H5. v Applications All position welding of shipbuilding, bridge, building and structural Fabrications. v Characteristics Supercored 71H is a titania flux cored wire for all position welding on Usage with high amperage. Its impact value is very good under high heat input, arc is smooth and slag detachability is excellent.
2 V Note on Usage 1. Proper preheating(50~150 , 122~302 ) and interpass temperature must be used in order to release hydrogen which may cause cracking in weld metal when electrodes are used for medium and heavy plates 2. One-side welding defect such as hot cracking may occur with welding parameter such as high welding speed. 3. Use 100% CO2 gas. Supercored 71H.
