  • Step – 2: Horizontally put the joining workpieces on the working table or the flat surface.
  • Step – 3: Now you need to align the male part of the bullet hinge vertically straight with the door and the metal frame. For your reference, the male part goes up and the female part goes down. You can use a scale, a rod, and two clips for finding the vertically straight position for the hinge.
  • Step – 4: Now if you are satisfied with the vertical alignment and the gap between the hinge and the metal door and frame, then tack weld at both sides. Usually, four points are welded. Both sides of the upper point, and both sides of the lower point.
  • Step – 5: At this point, you can remove the tool you have used for aligning the male post part of the hinge and fully weld head to toe of the hinge at both sides.
  • Step – 6: Adjust the bushing and put the female part.
  • Step – 7: Repeat step – 5 for the female part.

In this way, you can install a weld on hinge. 

8. How Do You Fit A Bullet Hinge?

First, put the male part vertically straight in between the two workpieces with a tool. Then when the gap and the straightness are aligned, then tack weld the upper portion and the lower portion.

After that, remove the tool and fully weld head to toe of the male part with the frame and the door.
