1. EQUIVALENT STANDARD AND CONFORMITY
- Vietnamese standard: TCVN 3223-2000 E513B.
- Vietnamese regulation: QCVN 21:2015/BGTVT-MW53
- American Standard: AWS E7018
- Japanese Standard: JIS D5016
- NK Registry: NK KAW53H10
2. DESCRIPTION
- E7018 has base cover, which is supplemented with a large amount of Manganese, Silicon and rare earth, to ensure the weld has extremely small impurities, high bearing strength.
- The flour content in the coating has strongly reduced hydrogen, so theE7018welds contain very low hydrogen content, ensuring resistance to hot and cold thermal cracking and high weld toughness.
- E7018can weld in all positions with a stable arc, strong pressure, weld pool, ease of peeling and cleaning slag, no slag, porosity, etc. Especially when trực tiếp bóng đá keo nha cai with a DC power source,E7018gives excellent results.
- The trực tiếp bóng đá keo nha cai rods weld low-carbon and low-alloy steels with tensile strengths of 500 N/mm2.
- E7018is the best choices for welded structural strength problems and are suitable for ship structures, construction, wharves, heavy load beams, pressure tanks, etc.

7. INSTRUCTIONS FOR USE
- Fully preparing the elements of labor safety before trực tiếp bóng đá keo nha cai. trực tiếp bóng đá keo nha cai power source is stable.
- When the trực tiếp bóng đá keo nha cai rod is moist, trực tiếp bóng đá keo nha cai is vulnerable to smoke, splashed and unstable, weld is clarified, need to dry at 200oC in 40 – 60 minutes before use.
- Removing all traces of oil, dust and dirt on the surface of the trực tiếp bóng đá keo nha cai material.
- Making sure the weld gap, bevelled edge of trực tiếp bóng đá keo nha cai materials as prescribed to achieve strong weld.
- Selecting the trực tiếp bóng đá keo nha cai line according to the instructions to obtain the deep weld, high working ability.
