1. EQUIVALENT STANDARD AND CONFORMITY
- Vietnamese regulation:QCVN 21:2015/BGTVT-D308
- American standard: AWS A5.1 E308
- Japanese standard: JIS D308-16
2. CHARACTERISTICS AND APPLICATION
- G-308 is suitable for fpt play trực tiếp bóng đá austenitic stainless steel (Inox) of all kinds, such as E304, E305, and E308, sometimes with good mechanical quality, high strength, and toughness. G-308 is also used in structures that are subject to heavy loads and have high wear resistance.
- G-308 is suitable for fpt play trực tiếp bóng đá medical equipment, household appliances, chemicals, civil art structures, stainless steel tanks, steel handrails, etc.
- G-308 has a bright, smooth, easy to remove slag, light electricity, quiet explosion, low smoke, little splash, and a stable arc.
- G-308 is a type of fpt play trực tiếp bóng đá rod with a high lime-titanium coating, designed with austenitic weld metal with low hydrogen content and supplemented with a large amount of rare alloying elements such as chromium, nickel, and rare earths to ensure the metal system E308, so it has anti-rust, acid-resistant, and very high mechanical properties.

7. INSTRUCTIONS FOR USE
- Fully preparing the elements of labor safety before fpt play trực tiếp bóng đá. fpt play trực tiếp bóng đá power source is stable.
- When the fpt play trực tiếp bóng đá rod is moist, fpt play trực tiếp bóng đá is vulnerable to smoke, splashed and unstable, weld is clarified, need to dry at 100oC – 150oC 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 fpt play trực tiếp bóng đá materials as prescribed to achieve strong weld.
- Selecting the fpt play trực tiếp bóng đá line according to the instructions to obtain the deep weld, high working ability.
