Oxyfuel gas welding
Key:
Torch tip
Filler rod
Flame (outer envelope)
Fusion (molten metal)
Base metal
Weld metal (solidified)
Description:
The torch tip emits a flame, forming a weld pool beneath its center. A metal filler rod can be fed from a side angle and dissolved into the molten weld pool. Fusion between base and filler metals occurs in this molten puddle, shielded by the outer envelope of the flame. Behind the torch's path, a line of solidified weld metal forms.
