ER317L
Description:
The main component of the welding wire is ultra-low C-18Cr-12Ni-3Mo, which is a stainless steel gas-shielded welding wire. Mo-containing anti-corrosion performance is good for acetic acid, sulfurous acid, phosphoric acid and salts. Good welding operation - Stable arc, beautiful appearance, less spatter. All-position welding.
use:
For petrochemical equipment, such as 0Cr19Ni13Mo3 (SUS 317) and other materials welding.

Precautions:
1. Protective gas: pay attention to the purity of the protective gas mixture ratio recommended Ar + 1-3% O2.
1. It is recommended to use Ar + 1-3% O2.2 to protect the gas ratio.
2. Gas flow: 20-25L / min.
3 dry elongation: 15-25mm.
4. The welding parts of the rust layer, moisture, oil, dust and other clean.
5. Outdoor welding, when the wind speed is greater than 1.5m / s windbreak measures should be taken, there must be appropriate windbreak measures to prevent the occurrence of pores.
The above suggestions are for reference only, in the specific operation to the scene prevail. If necessary, process assessment and then determine the welding program.
