When welding two metal pieces, what is the desired outcome?

When welding two metal pieces, the primary goal is to achieve a strong and durable fusion between the two materials. This ensures that the joint can withstand the stresses and loads it will encounter during its use. A strong weld results from proper heat application, filler metal, and technique, ensuring that the base metals are fused effectively without significant defects such as cracks or voids.

While the aesthetic appearance of the weld may be important in certain applications, it is not the primary objective. The weight reduction of the joint and flexibility are generally not desired outcomes in welding, as they may indicate weaknesses in the joint or inadequate structural integrity. Thus, focusing on creating a robust and durable fusion is essential for the safety and performance of welded assemblies.
