Deskripsi
Karakteristik:
LFC-2594 is a Flux cored wire designed to welding ferritic-austenitic superduplex steel and equivalent. Can also be used for joints between superduplex grades and austenitic stainless steels or carbon steels. High tensile strength as well as an excellent resistance to stress corrosion cracking and localized corrosion in chloride containing environments. The operating temperature range is –40ºC to 220ºC
Aplikasi:
It is suitable for welding of heat exchanger, chemical equipment, pumps, vessels and pipes processing chloride containing solutions.
Catatan tentang Penggunaan:
1. Use 100% CO₂ shielding gas.
2. Trailer Shield is required to ensure the weld pool completely shield until solidification is complete and no porosity problem.
3. Follow the recommended welding parameter to achieve good sound welds.
4. To prevent the welding defects due to improper gas shielding, the welding place should have the proper protection from wind.
