How far must thermite welds be placed from existing plant welds?

The correct answer indicates that thermite welds should be placed at least 2 feet away from existing plant welds. This practice is essential for several reasons related to safety and the structural integrity of the overall joint.

Firstly, thermite welding involves the use of extremely high temperatures, often exceeding 2500 degrees Celsius. By maintaining a distance of 2 feet from existing welds, it helps to minimize the risk of thermal damage to those nearby welds, which could lead to weakening or failure of the original joint.

Secondly, this spacing allows for proper heat dissipation during the thermite welding process, reducing the likelihood of compromising the mechanical properties of the existing welds due to overheating.

Additionally, maintaining this distance ensures that any potential slag or molten metal produced during the thermite process does not adversely affect the quality or performance of the surrounding welds, thus safeguarding the integrity of the entire assembly.

In summary, placing thermite welds at least 2 feet from existing plant welds is crucial for preserving the functionality and safety of the welding work.
