Will the Back of Sheet Metal Welding Points Rust?
1 Answers
There is a possibility of rusting at the back of sheet metal welding points, making the selection of sheet metal materials crucial: 1. Good Weldability: Many automotive sheet metal parts are joined through spot welding, oxy-welding, arc welding, or gas-shielded welding, requiring the sheet metal parts to have excellent welding properties. This is particularly important in automotive repair and patching, as materials with good weldability exhibit high welding strength and low tendency to crack. 2. Good Chemical Stability: Most automotive body panels operate in open environments, frequently exposed to water and steam, especially components like mufflers, which often work under high temperatures and corrosive gases. This demands that sheet metal parts possess good chemical stability, resisting corrosion at room temperature with strong rust-proof capabilities, and remaining corrosion-free and deformation-free under high temperatures or prolonged sun exposure.
