What is an expected outcome of proper fusion in a weld?

A strong bond between the base metals is an expected outcome of proper fusion in a weld. When welding, fusion occurs when the base metals melt and combine effectively, ensuring that the metallurgical properties of the joined materials are maintained or enhanced. Proper fusion is crucial because it determines the integrity and overall strength of the weld joint.

If the fusion is insufficient, it can lead to issues such as incomplete penetration or weak interfacial bonds, which compromise the strength of the connection. A strong bond is essential for the durability and functionality of welded structures, especially in applications where the welded joints will face substantial loads or stress.

While aesthetic appearance may be a consideration in some projects, it is secondary to the structural integrity provided by a strong bond resulting from proper fusion. Additionally, reduction of welding time might occur with certain techniques or efficiencies but is not a direct outcome of proper fusion itself. Therefore, affirming that a strong bond is the primary and most critical outcome of effective fusion in welding aligns with the principles set out in the API 1104 standard.
