Characteristics and Application

AWS A5.5 E8018-C3 Welding rods, welding electrode is an iron powder low hydrogen electrode for the welding of Iow temperature service steel in all positions. The weld metal contains 1.0%Niø It is suitable for the welding of LPG tanks, The welding can be done with good X-ray soundness, high deposition rate, and good impact value at -40℃. Proper base metals are also including high-carbon steel, low Manganese alloy Steel, 540—610 N/mm2 high tensile Steel, cast iron, Steel pipe for Iow temperature service, pressure vessel, ASTM A225 Gr D/A333 Gr1&6/A607 Gr60/A707 Gr.L5.L6, 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℃.
