Characteristics and Application

AWS A5.5 E8018-C2 Welding rods, welding electrode is an iron-powder low hydrogen electrode for the welding of low temperature service steel. It provides good impact value at -75℃. The weld metal contains 3.5%Ni. It is suitable for the welding LPG tanks or 3.5%Ni steel for low temperature service. The welding can produce good X-ray soundness, high deposition rate. Proper base metals are also including high-carbon steel, low Manganese alloy steel, 540—61 ON/mm2 high tensile steel, cast iron, steel pipe for low temperature service, pressure vessel, ASTM A333 Gr.3.4.7.9/A336 Gr.F31/A350 Gr.LF3/A352 Gr.LC3/ A420 Gr.L7.L8/A757 Gr.B3N.B3Q/A765 Gr.3, etc..

Notes on usage:

1. Be sure to clean up the contaminations on the base metal and welding seam so as not to derogate the weld metal quality from particles.
2. Maintain short arc length. Moving range should be controlled within 3 times of the wire's dia when you are welding with weave method.
3. Dry the electrodes at 350—400℃ for 60 minutes before use. Take out a batch of half day
consumption and keep in the environment at 100—150℃ during welding process.
4. Do not exceed the range of recommended current. Over heat input might decrease the impact value.

5. Pre-heat at 50-100℃ and PWHT at 600-620℃.
