What is the correct procedure to fabricate a 2 piece square to round with a 1" flange out and a collar?

The correct procedure for fabricating a 2 piece square to round with a 1" flange out and a collar involves kinking the body to the round shape first, then forming the flange out, followed by spot welding the body seam, and finally spot welding the collar.

Beginning with the kinking of the body to round ensures that the basic shape is established before any additional components are added. Kinking the square body to a round form makes it easier to manage and work with as you progress to shaping the flange.

Once the body is in the correct rounded form, forming the flange out is the next logical step. This process ensures that the flange will properly align for attachment to other components or surfaces, maintaining the integrity of the structure and sealing capability.

After the flange is formed, the body seam is then spot welded, securing the body in its round shape. This sequence is critical, as any adjustments to the flange after the seam is set could hinder the overall structure and alignment.

Finally, spot welding the collar completes the fabrication process. The collar is attached last, ensuring it aligns correctly with the already formed and welded components.

This systematic approach not only ensures efficiency but also maintains structural integrity and quality in the finished product.
