Weld-on Barrel Hinges |
|
Weld-on hinges, also known as barrel hinges and lift-off hinges,
provide a strong, compact, and attractive method of attaching metal
doors to metal frames for electrical, agricultural, security, safe,
tool cabinets, gate, enclosure, and many other industrial
applications. Weld-on hinges are available in steel, stainless
steel, and aluminum, with steel, brass, and stainless steel pins,
and with or without grease fittings. All sizes shown below are
available, many items are kept in stock. Please read
below: Design Considerations and Instructions
for the Proper Fit-Up and Welding of Weld-On Hinges. |

Design Considerations and Instructions for the Proper Fit-Up and
Welding of Weld-On Hinges. |
|
1) Lift-Off Door Applications |
|
In most lift-off door applications of weld-on hinges, the male
barrel (the barrel with the pin) is welded to the frame structure.
Why? Lift-off doors get dropped. Hinge pins on these dropped doors
get bent. Therefore, female barrels (the hinge barrels without
pins) shoud be welded to the door. |
|
2) Non-Removable Door Applications |
|
Weld-on Hinge Pin Orientation
- Functionally, there is a load advantage to having the male
barrels attached to the frame, top and bottom, pointing towards each
other. Reason: greater spread between hinges. |
|
A consideration: Make sure to allow sufficient clearence for a
grease gun when mounting the female barrel of a weld-on hinge with a
grease fitting. |
|
3) Fit-up |
|
a) Tack weld the male barrel of bottom hinge to the frame. Insert
bushing over pin. |
|
b) Accurately fit-up door and tack female barrel of bottom hinge to
door. |
|
c) The bottom hinge now supports the weight of the door while
fitter holds the top. |
|
d) With door accurately fitted, align the hinges with a straight
edge along the weld tabs assuring that all hinges pivot about the
same axis. |
|
4) Welding |
|
Weld along the full length of the weld tab. |
|
Caution: DO NOT allow the weld to penetrate
through the wall of the female barrel, welding the barrel to the
pin. This is a frequent mistake. The hinge is no longer a hinge
since all parts are welded together, and it is time to start
grinding it off. |
