1. EQUIVALENT STANDARD AND CONFORMITY
- Vietnamese standard: TCVN: 3223-2000-E513
- Vietnamese regulation: QCVN: 21:2015/BGTVT-MW53
- American standard: AWS A5.1 E7016
- Japanese standard: JIS D5016
- NK Registry: KAW53H10
2. CHARACTERISTICS AND APPLICATION
- E7016 have base cover, which is supplemented with a large amount of Manganese, Silicon and rare earth and so on, to ensure the weld has extremely small impurities, high bearing strength.
- The flour contained in the casing has strongly reduced hydrogen, so the E7016 welds contain very low hydrogen content, ensuring resistance to hot and cold thermal cracking and high weld toughness.
- E7016 can weld in all positions with a stable arc, strong pressure, weld pool, ease of peeling and cleaning slag, no slag, porosity, etc. Especially when welding with a DC power source, E7016 gives excellent results.
- E7016 welding rods weld low-carbon and low-alloy steels with tensile strengths of 500 N/mm2.
- E7016 are 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 welding. Welding power source is stable.
- When the welding rod is moist, welding 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, dirt on the surface of the weld.
- Making sure the weld gap, bevelled edge of welding materials as prescribed to achieve strong weld.
- Selecting the welding line according to the instructions to obtain the deep weld, high working ability.
