• Proprietary formulation for maximum safety margin welding crack repairs or joining a broad range of difficult-to-weld steels of unknown specification and in dissimilar combinations at ambient service temperatures
• Outstanding weld tensile strength properties
• Ultimate resistance to hot cracking weld solidification defects
• Wide dilution tolerance even for contaminating trace elements
• Superior resistance to hydrogen induced cold cracking defects
• elf releasing slag for inclusion-free, smooth, regular weld profiles
• Machinable, stainless deposits which rapidly work harden under pressure
• Easy striking & restriking weldability in most positions
• Electrodes available in a complete range of diameters

Repair and build-up of drop forging tools and damaged profiles

Drop forging dies, punches, inserts.

•   Superior deformation resistance at high temperatures.

•  Excellent compatibility with die block steels.

•  Machinable with tungsten carbide tool.

•  All position weldability.

Joining and build-up on all drop forging tools. Repair of worn out or damaged profiles. Salvage scrapped undersized die- blocks by total re-build with weld metal. Overlaying of complicated profiles requiring combination of high hardness and toughness combined with good machinability such as gear pinion teeth.

• Good resistance to saltwater corrosion and steam
• Same colour as bronze
• Easily machinable deposit
• Low coefficient of friction
• All-position weldability
• Exceptional arc stability in AC
• ApplicationsPump bodies, Propellers, Impellers , Friction bearings, Shipbuilding applications, Dissimilar joining of bronze with steel and cast iron

• Augers, screw conveyors, scrapers, paddles, wear pads, impactor bar, pusher shoes, impeller etc.

• Superior abrasion & moderate impact resistance.
• Cold arc coating with superior weldability.
• Smooth, ripple free deposits.
• Excellent resistance to erosion.

• Applications where a combination of two or more wear factors like abrasion, erosion, corrosion combined with moderate impact. Deposits are ripple free and hence offer high wear resistance.

• Clean metal surfaces. Use EWAC GOUGETRODE electrode to remove damaged metal. Preheat is recommended for alloy steel, cast iron and also maintain preheat temperature while welding. Maintain medium arc with electrode at an angle of 80°-90° from horizontal direction of travel.

• Joining dissimilar steels, dies, tools, springs, machinable build-up & overlay.
  Outstanding Features:
  
  • Refined grain structure with improved strength and ductility.
  • Superior crack resistance.
  • Spray type metal transfer.
  • Joining steels of unknown composition.
  • Machinable built up and overlay.
    Recommendation:
    
    • Cold arc coating plus high alloy core generates highly ionized arc for spray transfer of weld metal. Addition of special micro alloying elements produces refined grain structure.
    • Recommended for similar and dissimilar steels. Suitable for joining steels of different section thickness.
      Procedure:
      
      • Clean weld area. Bevel heavy sections. Tilt electrode 10°-15° in direction of travel. Burn-off rate is rapid and uniform permitting rapid advance with no “sticking” or “drifting”. Restrict weaving to 2-3 X electrode diameter. Peen to relieve stresses. Slag releases easily. Restrict Preheat to 150°C max.
