About ER308L - TIG Stainless Steel Welding Rod - 36" X

ER308L - TIG (GTAW) - STAINLESS STEEL AWS A5.9 Welding Positions: All INTRODUCTION: The main component of ER308L is ultra-low carbon 18Cr-8Ni; it is ultra-low C Stainless steel TIG welding rod. The intergranular corrosion resistance of the weld metal is more excellent. Welding smoothly, weld bead smoothly, excellent corrosion-resistance, crack-resistance for acetic acid, sulfuric acid, phosphoric acid and salt corrosion because it contains Molybdenum. USES: Sheet metal on the corresponding stainless steel base metals. High pressure piping and tubing. It is widely used in petrochemical, food machinery, medical equipment, chemical fertilizer equipment, textile machinery such as 022Cr19Ni10 (SUS 304L) and other materials of welding.

Shielding gas: Adopt pure Argon gas. Recommendation flow rate: 9-14L/min (AMP 100-200A), 14-18L/min (AMP 200-300A). 2. Tungsten extension: 3-5mm, Arc length: 1-3mm. 3. Wind speed limited: ?1.0m/s. 4. Use longer backflow of argon shield gas to get better welding result. 5. Mechanic property and metal anti-cracking ability of the welded metal relative by energy pass value on the wire. 6. The welding should be operated in clean surface without rust, moist, oil contamination and dust. The above parameters are for reference purpose and depend on diverse factors. Run tests, evaluate and set your welding parameters before starting the welding job.
