Techalloy 99 - 200g Pack Ni99 2.4mm TIG Filler Rods for Cast Iron

Lincoln Techalloy 99 is used for TIG and MIG welding of cast iron. This wire is extensively employed to repair grey iron castings. It can also be used for overlay and buildup. A preheat and inter-pass temperature of 350°F (175°C) minimum is recommended during welding. Dilution from the casting influences the mechanical properties of the metal. Due to the high nickel content, the welds are not readily machineable.

Features:  

• Welds produced are generally more machinable than a Tech-Rod® 55 deposit
• A preheat and inter-pass temperature of not less than 350°F (175°C) is required during welding on cast iron to minimize the potential for cracks
• 200g pack 
• 5 rods (approx)
• 100cm long rods (approx)
• Brand - Lincoln

Applications: 

• Used for welding of cast irons to other cast irons as well as for joining cast irons to mild steels and stainless steels
