Welding FAQs, answered by experts

Since water heaters are primarily made of metal, they’re commonly accepted by scrap yards and collectors. Don’t expect to fetch a high price, though—water heaters are mostly steel and aluminum, which aren’t high-value metals.

The best tool to use for straight lines is either a circular saw or table saw. When cutting shapes, a jigsaw will be the easiest and most precise tool to use. 

To maintain custom or fabricated metal structures and extend their lifespan and appearance, perform regular cleaning, apply rust prevention treatments, and use protective coatings.
