Abstract

A method for reducing an amount of manganese in a fume generated during arc welding including incorporating a quantity of manganese in a core of a welding electrode as a composite particle of manganese and a shielding material.

Claims

exact text as granted — not AI-modified
1 . A method for reducing an amount of manganese in a fume generated during arc welding comprising incorporating a quantity of manganese in a core of a welding electrode as a composite particle of manganese and a shielding material.  
   
   
       2 . The method of  claim 1  wherein said shielding material is TiO 2 .  
   
   
       3 . The method of  claim 2  wherein said TiO 2  is rutile.  
   
   
       4 . The method of  claim 2  wherein said TiO 2  is anatase.  
   
   
       5 . The method of  claim 1  wherein said incorporating step includes encapsulating said manganese with said shielding material.  
   
   
       6 . The method of  claim 1  wherein said incorporating step includes dispersing said manganese in a matrix of said shielding material.
