CHT308L stainless steel flux cored wire (Y308L) comply with: GB / T17853E308LT1-1 AWS A5.22E308LT1-1 Description: CHT308L belong rutile stainless steel wire, is the most widely used austenitic stainless steel welding material. It can be all-position welding. Excellent performance welding process, arc stability, weld appearance, less spatter, smooth wire feeding. Weld has good heat resistance, corrosion resistance. Uses: For SUS304, SUS304 stainless steel, used in petrochemical, pressure vessels, medical equipment, food machinery, fertilizer and other fields.

The use of CO2 gas, CO2 gas purity above 99.98%. 2. When welding CO2 shielding gas flow rate should be controlled at 20-25L / min. 3. The extension length of the wire should be controlled within the range of 15-25mm. The weld should be removed before welding parts of the oil, dirt and rust layer. 5. outdoor welding, when the wind speed is greater than 1.5m / s should take their precautions, there must be adequate wind facilities, to prevent blowholes.
