WELDING ELECTRODES :

 
 

Quality starts from buying right type of raw-materials from the accredited suppliers. Plant and machinery used in production is a prime factor. Bangladesh Welding Electrodes Ltd. producing Welding electrodes using the total machinery from OERLIKON – Switzerland. As such the quality is self-controlled at each stage of production.

 
     
 
 
     
 
 
     
     
 

INDUSTRIAL OXYGEN :

 
 
Industrial Oxygen is produced by liquefaction of natural air through cryogenic process. Air is liquefied at minus 1960 C from where liquid Oxygen and liquid Nitrogen are separated through fractional distillation and Gaseous Oxygen is filled into cylinders at a pressure of 2200 psi. For the purpose of cutting mild steel using DA, LPG or CNG as fuel gas, Oxygen purity requirement is 99.95% minimum.
 
     
 
For hospital use, this Oxygen purity is much less than the Industrial Oxygen purity normally 95.00% is safe for human inhalation. Oxygen produced through electrolytic process by dissociating water is harmful for the human inhalation.
