What is the correct order for completing a groove seam?

The correct order for completing a groove seam begins with forming the seam, followed by setting the seam, then offsetting it, and finally dressing it.

Starting with the formation of the seam involves shaping the metal pieces to create a groove that will accept the other section of metal. This initial step is essential because it lays the groundwork for a secure and effective seam.

After forming, setting the seam refers to the process of aligning and securing the metal parts together within the groove. Proper setting is critical to ensure that the joint is stable and will withstand the forces applied during use and installation.

The offsetting step involves adjusting the seam to achieve the desired fit and alignment, which is particularly important for ensuring that the joint maintains structural integrity.

Finally, dressing the seam means smoothing and finishing the joint to eliminate sharp edges and improve aesthetics, as well as maintaining airflow in HVAC applications. This finishing touch is significant in that it ensures safety and allows for a cleaner overall appearance.

These sequential steps are crucial to guarantee a reliable and high-quality groove seam in HVAC sheet metal work.
