Red Seal Sheet Metal Worker Practice Exam

Which of the following is NOT a common method for joining sheet metal?

1. Riveting

2. Screwing

3. Glazing

4. Soldering

The correct answer is: Glazing

Glazing is a term typically associated with the installation of glass in frames or other structures, rather than a technique for joining sheet metal. In contrast, riveting, screwing, and soldering are all established methods used specifically for metal fabrication. Riveting involves using metal pins that are deformed to hold two or more pieces of metal together, creating a strong mechanical bond. Screwing involves using screws to physically fasten pieces of metal together, allowing for easy disassembly if needed. Soldering, on the other hand, is a process of joining metal parts by melting a filler metal that has a lower melting point than the workpieces. All these methods facilitate the joining of sheet metal, reinforcing their relevance in the field of metalworking. Thus, glazing is correctly identified as not being a common method for joining sheet metal.
