DP TIG
DP TIG
DP TIG (Double Pulse Tungsten Inert Gas) Welding is an advanced welding process designed for precision welding of thin to medium-thickness metals, including stainless steel, aluminum, copper alloys, and specialty metals.
The double-pulse technique alternates between a high pulse for penetration and a low pulse for heat control, allowing welders to achieve superior weld bead appearance, reduced distortion, and precise heat management. This technology is widely used in aerospace, automotive, food processing, pharmaceutical, and high-end fabrication industries, where weld quality, aesthetics, and minimal heat-affected zones are critical.
DP TIG Welding is highly versatile, suitable for both manual and automated applications, and provides enhanced control over puddle dynamics, weld speed, and bead consistency, resulting in repeatable and reliable welds even on challenging materials and geometries.
Key Features
- Alternating high and low pulses improve penetration and control heat input, reducing warping and distortion.
- Adjustable pulse frequency, duration, and amplitude to suit different materials and thicknesses.
- Ideal for stainless steel, aluminum, copper, and exotic alloys.
- Produces smooth, uniform weld beads with minimal spatter.
- Allows programming of pulse sequences, travel speed, and torch parameters.
- Can be combined with rotary, orbital, or robotic welding setups for high-volume production.
SPECIFICATION
- The whole process will not penetrate the back liner side welding on both sides
- Wide application scope of multi-material
- Excellent in performance stability of high-quality
- low cost only a protective gas is extremely low maintenance fees.
