Which should be stronger?

The correct choice is deposited weld metal, as it plays a critical role in the overall strength of a welded joint. Deposited weld metal refers to the molten metal that is deposited during the welding process to create the joint between two pieces of base metal. This metal is engineered to have specific mechanical properties, which can be enhanced depending on the welding technique and materials used.

For a weld to be considered strong, the deposited weld metal should ideally have strength characteristics that meet or exceed those of the base metals being joined. This ensures that the welded joint can withstand the stresses it will encounter in service without failing. In addition, the metallurgical properties of the deposited weld metal, including its toughness, ductility, and tensile strength, can be optimized through various welding methods, filler materials, and post-weld treatments.

Understanding the strength of the deposited weld metal is essential for any welding professional, as it directly influences the durability and reliability of the welded structures they are creating. In contrast, while the base metal provides the foundation, and the electrode covering adds protection and support during welding, it is the deposited weld metal that actually forms the critical bond in the joint.
