Oxy-Fuel Welding & Cutting
Welding Electrode Or Rod: Bronze, Silver, Aluminum
Acetylene and Oxygen are used to weld or cut metals. Pure Oxygen instead of air is used to increase flame temperature to allow localized melting of the workpiece metals.
Theoretical Flame Temp:
Acetylene = 2,400 °C in air
Acetylene = 3,500 °C in Oxygen
Workpiece Melting Point:
Copper = 1,085 °C ; Brass = 925°C
Silver = 962 °C
Aluminum = 660 °C
Cons & Pros:
*Cylinder size is big and heavy.
*Much higher flame temp. can easily damage adjacent parts.
