What are some common repair techniques for sheet metal structures?

Patching, forming, and using splice plates are all common and effective repair techniques for sheet metal structures.

Patching involves covering holes or damaged areas with new sheet metal, which can restore the integrity of the structure. This technique is particularly useful for small areas of damage and can be done with various types of fasteners or adhesives to ensure the patch is securely attached.

Forming is a technique used to reshape or manipulate existing sheet metal to correct warping or other forms of deformation. This process can help restore the original functionality or appearance of the metal structure.

Using splice plates refers to the addition of metal plates to join two sections of sheet metal together, thereby reinforcing the structure and potentially extending its life. Splice plates are particularly useful in situations where a long piece of sheet metal is required, and a single piece is not available.

These repair methods highlight the practicality and versatility needed to maintain the durability and structural integrity of sheet metal structures. Other options mentioned, such as welding and painting, are also important but pertain more to joining materials or finishing surfaces rather than the specific repair techniques outlined in the question.
