Flux-cored wire for use with stainless steel
EnDOtec DO*500 S, Ø 1.2mm, 15.0 kg
Rutile-basic flux-cored wire for gas-shielded welding, designed for production processes, joints and build-ups where a high degree of reliability and dependability is required.
Suitable for joining and fabricating CrNi steels with low carbon content of types 316L, 316Ti and 316Nb.
Weld metal with a ferritic microstructure of 7.8 and 0.03%C max. Excellent resistance to intergranular corrosion and operating temperatures between -120°C and +400°C.
- High arc stability.
- Low heat input, lower dilution.
- Excellent weldability in all positions.
- Easy to remove slag.
- The high deposition rate reduces costs.

Welding guidelines
- Welding equipment
The flux cored wire DO*500 S is fully compatible with conventional power sources. Programmable equipment with pulsed arc provides optimum performance. - Preparation
Before welding, the workpiece must be provided with a bevel for X or V weld joints, which is particularly suitable for thick welded joints. The areas to be welded and the surrounding area must be kept particularly clean. - Preheating
Preheating is not normally required for stainless steels. However, if ferritic steel is to be joined to austenitic steel, it may be necessary to preheat the ferritic area, depending on the type and size of the workpiece to be welded. - Welding parameters
Welding current and polarity: DC= (+)
Stick-out: 10 – 20 mm
Ø (mm) 1.2
Voltage (V) 20 – 34
Current (A) 120 – 280 - Welding technique
To achieve a better penetration for welds that require multiple passes, the welding torch must be held at an angle of 70 – 80°. - Machining the weld
The weld metal can be machined or ground and can be cut with a gouging torch (Arc-Air) or a plasma arc. - Shielding gas
Recommended gas: 82% Ar, 18% CO2 [ISO 14175 M21]
Alternative gas: 98% Ar, 2% CO2 [ISO 14175 M12]
Flow (l/min): 14 - Welding positions
PA, PB, PC, PD, PE, PF, PG [ISO 06947]
