EnDOtec DO*505 S Flux-cored wire

EnDOtec DO*505 S, Ø 1.2mm, 15.0 kg

Rutile-basic flux-cored wire for gas-shielded welding, designed for large-scale series, joints and overlays where a high degree of reliability and dependability is required.
Ideal for general maintenance work, particularly suitable for joining difficult-to-weld steels, hardening steels and steels with a high carbon content, etc.
Duplex type weld with high tensile strength. Balanced nitrogen content. The carbon and molybdenum content also ensures excellent resistance to intergranular corrosion, cracking and stress corrosion cracking in solutions with a high chlorine concentration.

• High arc stability.
• Low heat input, lower dilution.
  
  
• Excellent weldability.
• Easy slag removal.
• High deposition rate.

Processing instructions

• Welding equipment
  The flux cored wire DO*505 S is fully compatible with conventional power sources. Programmable units with pulsed arcs provide optimal performance.
  
  
• Preparation
  Before welding, the workpiece must be provided with a bevel for X or V weld joints, which is particularly suitable for thick welds. The areas to be welded and the surrounding area must be kept particularly clean.
  
  
• Preheating
  Preheating is not normally necessary 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: 15–20 mm
  Ø (mm) 1.2 
  Voltage (V) 20 – 34 
  Current (A) 120 – 280
  
  
• Welding technique
  To achieve better penetration for welds requiring 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]
  Gas flow (l/min): 14
