Description

KISWEL T-50 TIG Welding Wire – ER70S-6 – 1000 mm Rods, 5 kg Tube

KISWEL T-50 TIG welding wire is a high-quality solid filler rod engineered for welding mild steel and 490 MPa tensile strength structural steels. It is ideal for welding of structural components, heavy machinery, construction steelwork and vehicle fabrication and repair.

With a balanced chemical composition and strong deoxidizing elements (Si, Mn), T-50 provides:

• Stable and smooth arc

• Clean weld pool with low porosity

• Reliable fusion even on steel with light mill scale or surface contaminants

Supplied as 1000 mm TIG rods in 5 kg tubes, this wire is a robust choice for professional workshops, fabrication shops and industrial maintenance teams.

2. Classification and Standards

KISWEL T-50 complies with major international standards:

• AWS A5.18: ER70S-6

• EN ISO 636-A: W 46 3 W3Si1

• EN ISO 636-B: W 49A 3 U W6

• JIS Z 3316: YGT50

• KS D 7140: YGT50

This classification makes it fully compatible with welding procedures requiring ER70S-6 class TIG filler for carbon and low alloy steels.

3. Typical Applications

• Welding of mild steel and 490 MPa structural steels

• Fabrication of steel structures, frames and beams

• Machinery and equipment manufacturing

• Vehicle chassis, body and components

• General industrial and workshop TIG welding where strong, ductile welds are required

4. Key Features and Benefits

• High-strength weld metal
  Yield strength around 490 MPa and tensile strength approx. 580 MPa.

• Excellent weldability
  Smooth arc, good wetting and easy control of the weld pool.

• Strong deoxidizing action
  Optimized Si and Mn levels allow good results even on lightly contaminated or mill-scaled surfaces.

• All-position capability
  Approved for flat, horizontal, vertical and overhead TIG welding.

• Consistent quality
  Tight tolerances on chemistry and mechanical properties for repeatable results.

• Certified product
  Approved by major classification societies (ABS, BV, LR, KR – see below).

5. Typical Chemical Composition of Wire (%)

• C: 0.08

• Si: 0.82

• Mn: 1.52

• P: 0.012

• S: 0.015

• Cr, Ni, Mo: Not intentionally added

This composition corresponds to a standard ER70S-6 filler, offering high strength and good toughness.

6. Typical Mechanical Properties of All-Weld Metal

• Yield Strength (Y.S): 490 MPa

• Tensile Strength (T.S): 580 MPa

• Elongation (El.): 30 %

• Impact Value (IV): 130 J at -30 °C

• PWHT: Not required in standard applications

These values confirm T-50 as a reliable choice for structural and industrial steel welding, including applications exposed to low temperatures.
