In the upset butt welding:
  • a)
    The faces of the metal pieces to be joined are prepared for even contact
  • b)
    Heating is obtained by the contact resistance of the metal pieces to be welded
  • c)
    The voltage required is 2-8 V and the current required ranges from 50 A to several hundred amperes depending upon material and the area to be welded at a time.
  • d)
    All of the above
Correct answer is option 'D'. Can you explain this answer?
Verified Answer
In the upset butt welding:a)The faces of the metal pieces to be joined...
In upset butt welding, the two metal parts to be welded are joined end to end and are connected across the secondary of a welding transformer
Due to the contact resistance of the metals to be welded, heating effect is generated in this welding.
The voltage required is 2-8 V and the current required ranges from 50 A to several hundred amperes depending upon material and the area to be welded at a time
