how is S.W.A.T Changing TIG Welding Forever ?
S.W.A.T delivers exceptional speed, cost savings, and weld consistency by redefining how TIG welding energy is applied to the joint.
Core Advantages of Sigma weld Accelerated Tig
Single-Pass Full Penetration
Achieves full penetration welds up to 10 mm in a single pass, eliminating multiple welding layers.
No Edge Preparation Required
Square edge joints can be welded without beveling or edge preparation up to 10 mm thickness.
Keyhole TIG with Digital HF Control
High-frequency digital arc control (~150 kHz) generates a stable plasma keyhole for deep penetration.
Extremely High Welding Speeds
Enables welding speeds up to 300 mm/min on plates and ~400 mm/min in tube mill applications.
Radiographic-Quality Welds
Produces highly repeatable, X-ray quality welds validated through ASME Section IX testing.
Lower Heat Input & Minimal Distortion
Concentrated arc reduces heat input, minimizes HAZ, and lowers post-weld distortion.
Reduced Gas & Filler Consumption
Consumes as little as ~10% shielding gas and significantly reduces filler wire usage.
Automation & Production Ready
Designed for tube mills, orbital welding, and automated production lines using a single TIG power source.
100%
Weld edge preparation eliminated for joints up to 10 mm thickness
90%
Reduction in filler metal consumption for most welds up to 10 mm
83%
Fewer welding passes by replacing multi-pass TIG with a single-pass process
70-75%
Overall reduction in total welding cost due to faster cycle times
60%
Lower shielding gas consumption compared to conventional TIG welding
30-40%
Lower heat input resulting in reduced HAZ(Heat Affected Zone) and minimal distortion
Pressure Vessels & Heavy Fabrication
Single-pass, full-penetration welds on thick stainless-steel sections
Radiographic-quality joints meeting ASME Section IX requirements
Eliminates edge preparation and reduces overall fabrication time
Tube Mills & High-Throughput Production Lines
Replaces PT-TIG welding with significantly higher line speeds
Consistent weld quality at continuous production rates
Designed for integration into inline tube and pipe manufacturing
Exotic & Reactive Alloy Welding
Proven welding of titanium, nickel, cobalt, and alloy steels
Low heat input minimizes distortion and metallurgical degradation
Stable arc control ensures repeatable, high-quality welds
Automated & Orbital Welding Systems
Fully compatible with orbital heads and mechanized torch systems
Consistent penetration and weld profile in automated environments
Ideal for high-repeatability and precision welding applications
