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.
