Why is it important to monitor the welding gap during alignment?

Monitoring the welding gap during alignment is crucial for achieving structural integrity. The welding gap refers to the space between the components being joined. Properly controlling this gap ensures that the weld can penetrate effectively and form a strong bond between the materials. If the gap is too wide or uneven, it can lead to inadequate fusion, resulting in weak spots within the weld that may compromise the entire structure's strength and durability.

In thermite welding, maintaining the correct gap allows for optimal heat distribution and penetration of the molten metal, which is essential for ensuring that the weld meets its intended load-bearing requirements. A well-executed weld with the correct gap will enhance the overall performance and longevity of the welded joint, thereby ensuring that the structure can withstand the applied stresses it may encounter during use.
