ES 71T1C A5.20: E 71T-1C / EN 17632-A: T 42 2 P C 1
Description
ES 71T1C Is used for all positions welding of machinary, ship building, bridges. Impact values of weld metal are good.
ES 71T1C is a flux cored wire which has been designed to get a good usability in all position for wide range of welding currents. With its quiet and smooth arc, its slag detachability is very good..

Note on Usage ES 71T1C
1. Proper preheating(50~ 150?) 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 defects such as hot cracking may occur with wrong welding parameter such as high welding speed.
3. Use 100% CO? gas.
4 . Welding Current is DC + & Welding position are 1G , 2F , 3G , 4G.
