OK, back to the build!!! The burner duct flange ring that I made a week ago was ready for welding. To weld the ring into place I needed to position it at the end of the burner duct pipe making sure it is square to the axis of the pipe. I tapped the snug fitting ring into the pipe and then used a carpenters “rafter” square against my workbench to check the flange’s position (not shown). This was done while rotating the pipe to guarantee an axial trueness.
Once I was happy with the position of the ring I tacked it in with the TIG welder. I then laid down a nice even bead around the flange ring as seen below.
