The ease of assembling a welded locker can depend on several factors, such as the specific model of locker, the level of experience of the person assembling it, and the available tools and equipment.

Generally speaking, welded lockers can be more difficult to assemble than their unassembled counterparts, such as knock-down or riveted lockers, as they often require welding and other specialized equipment to put together. However, if you have experience with welding and the necessary tools at your disposal, assembly can be relatively straightforward.

It's important to carefully read and follow the manufacturer's instructions, as well as any safety precautions or warnings. Additionally, it may be helpful to have a second person to assist with the assembly, as some parts may be heavy or awkward to handle alone.

Overall, the ease of assembling a welded locker will depend on the specific circumstances and individual factors involved.
