How many tie spikes or clips must be removed from each side of the weld crib?

• A. 1
• B. 2
• C. 3
• D. 4

Answer: (A)

In thermite welding, the removal of tie spikes or clips is essential to properly prepare the welding area and ensure a successful weld. The correct approach is to remove one tie spike or clip from each side of the weld crib. This allows for the thermal expansion and contraction that occurs during the welding process while maintaining the stability of the rails or components being joined. Removing one tie spike from each side (a total of two) provides the necessary clearance for the molten thermite to flow into the joint without obstruction. This step is crucial because leaving too many spikes or clips in place could hinder the weld quality, potentially leading to defects or structural weaknesses in the final weld. Proper preparation is key in thermite welding practices, and understanding how many attachments to remove helps ensure both safety and the integrity of the welding joint.
