CAST IRON NON-MACHINABLE WELDING ELECTRODES
 
 Classification/Coding :  AWS A/SFA5.15 Est
 Characteristics :
 
GELCAST- NM is a medium-heavy coated, low hydrogen type electrode for  non-machinable welds on cast iron. The electrode should be preferred when   a strong and rigid joint is to be obtained between two cast iron parts.   Pre - heating is recommended for heavy and complicated section.
KEEP   DRY.
  
  Application :
 
Welding of cast iron parts for all types of general reclamation or repair work, where machinability is not a primary consideration, joining cast iron to  mild steel etc.

 Special Note : Re-dry for 1 hrs at 120˚ C prior to use. Before starting the weld make sure that casting   is absolutely free from grease, oil, rust, paint or dust. For heavy and complicated sections. Preheat to a   minimum temperature of 400˚C is recommended. Bereling is recommended even on the thinnest   sections. For holding thermal stresses to a minimum, small diameter electrodes and low current values   are recommended.
