Red Seal Sheet Metal Worker Practice Exam 2025 – Complete Guide

Question: 1 / 400

What is the primary purpose of flanging in sheet metal work?

To reduce weight

To create a lip or edge for better joining and strength

Flanging in sheet metal work primarily serves to create a lip or edge that enhances the joining process and improves the overall strength of the metal component. This technique involves bending the edges of a sheet of metal at a right angle or other specified angle, allowing for a greater surface area for welding, riveting, or fastening. By creating this lip, flanging helps distribute stress more evenly and can provide additional structural integrity, which is crucial in applications where strength and durability are required.

While reducing weight, enhancing appearance, and improving heat resistance are potential benefits one might consider in metalwork, these are not the main reasons for implementing flanging. The primary focus of flanging is firmly rooted in its functional benefits related to strength and joining capabilities.
