Can stainless steel be TIG welded?
Yes, stainless steel is ideally suited for TIG welding. GTAW/TIG produces exceptionally clean, high-quality welds on all stainless steel grades including austenitic (304, 316), ferritic, and martensitic alloys. The process provides superior control over heat input, penetration depth, and weld pool characteristics, making it the preferred method for critical stainless steel applications in aerospace, medical, nuclear, and food processing industries where weld integrity and corrosion resistance are paramount.
What polarity for SS TIG?
Stainless steel TIG welding uses Direct Current Electrode Negative (DCEN) polarity, also called straight polarity. This configuration directs approximately 70% of the heat into the workpiece, providing deep penetration and narrow weld beads while minimizing tungsten electrode consumption. DCEN polarity is standard for all stainless steel grades and thicknesses when using GTAW processes. Our certified welders maintain proper polarity settings throughout all stainless steel TIG welding operations.
What amps should I TIG weld stainless steel?
Amperage for stainless steel TIG welding depends on material thickness, joint configuration, and welding position. As a general guideline: 0.5mm material requires 15-30 amps, 1.5mm needs 40-60 amps, 3mm requires 80-120 amps, and 6mm demands 150-200+ amps. Our welding procedures specify precise amperage ranges, pulse parameters, and heat input controls based on your exact application requirements, ensuring consistent penetration, fusion quality, and dimensional stability across all production runs.
What makes TIG welding ideal for high-precision stainless steel applications?
TIG welding offers unmatched control over heat input, weld pool behavior, and filler addition, making it perfect for precision stainless steel work. The non-contact tungsten electrode and inert gas shielding produce exceptionally clean welds free from slag, spatter, and atmospheric contamination. This level of control enables tight tolerance work, cosmetic finishing, and consistent metallurgical properties critical in aerospace, medical device, and nuclear applications where weld quality directly impacts safety and performance.
