Weld-on hinges use smooth, entire leaves without any holes, which give them their name. They are made up of two leaves that come together in the center, much like all hinges. The two leaves come together to create a knuckle fastened by a pin. The linked leaves are held together by a pin put through their middles. Weld-on hinges do not have holes, unlike normal hinges containing two or more holes in each leaf. As they aren’t meant to be used with fasteners, they don’t need holes. Weld-on hinges, however, are intended to be fitted using welding. A welding torch can install a weld-on hinge to fuse each of its two leaves to the proper surfaces.
Weld-on hinges are a reliable, strong, and adaptable type of hinge. We provide a variety of hinges, such as bullet, heavy-duty, straight, double-pressed, and butt. Big duty weld-on hinges are great substitutes for more conventional hinges like butt and piano since they can support heavy loads and are acceptable for narrow frames.
Materials used for Weld-on Hinges
Iron, stainless steel, zinc-plated iron, low carbon steel, brass, steel, and aluminum alloys are typical materials used in weld-on hinges. The materials are drilled and cut to the precise shape of the hinge.
Some weld-on hinges have grease nipples that make it simple to lubricate the hinge pin, making them the perfect solution for large doors.
Construction of Weld-on Hinges
Extrusion is the initial step in the procedure used to create weld-on hinges.
In this procedure, a ram squeezes circular metal stock known as “billets” or “logs” through a die, a hollow profile that molds the metal as it is extruded into a particular form.
Weld-on hinges consist of two independent hinge parts that may be directly welded onto surfaces.
Weld-on hinges are also known as weld-on barrel hinges or plain barrel hinges since these portions are known as the male and female barrels.
The barrel with the pin is the male barrel, while the barrel without a pin is the female barrel.
In comparison, the male barrel is fastened to a structural surface, e.g., a door frame, and the female barrel is welded to the other surface, e.g., a door.
The barrel without the pin should be placed on top because most lift-off doors often descend. As a result, the bottom barrels can support the door with exceptional load-bearing.
For very heavy weights, heavy-duty weld-on hinges are an additional choice.
Working of Weld-on Hinges
Weld-on or bullet hinges have three essential components:
The barrel side without a pin, sometimes referred to as the leaf side or female
The pin-equipped barrel side, often known as male
The bush, which straddles two divisions
Male barrels are welded to structural surfaces, whereas female barrels are welded to the surface that needs to move.
The female barrel needs to fit on top of the male barrel since doors with weld-on hinges are lift-off.
This is because lift-off doors are frequently dropped. Therefore, the bottom barrel has to be more capable of bearing weight than the top.
Lift-off doors can be easily removed from the hinges at any moment without the inconvenience of having to unscrew them.
For added security, weld-on hinges can be fastened so that the gate or door can either be permanently installed or never be removed by taking it off.
Benefits of Weld-On Hinges
Weld-on heavy strength door hinges provide clients several advantages with notable characteristics, including:
Pin made of precision-ground alloy steel
Non-handed for mounting with either the right or left hand
Dust sealing for harsh settings or outdoor use
Greater flexibility than conventional hinges
When utilized with certain things, weld-on hinges maintain the objects’ structural integrity. Pilot holes won’t need to be drilled into anything.
Applications of Weld-On Hinges
Weld-on hinges are utilized when attaching one to another metal surface requires welding.
They are perfect for various uses, including steel doors, gates, metal cabinets, containers, boats, and trailers.
Large, mainly zinc doors, such as those on refrigerators and freezers, are frequently covered.
Weld-on hinges are employed in industrial, commercial, maritime, automotive, shipping, building, and electronics sectors.
Other things include BBQ pits, fishing gear, tool chests, cab enclosures, security gates, traffic signal controllers, truck or trailer bodies, boats, and cabs.

Weld On HingesWeld on hinges are small hinges that connect two separate metal parts, typically doors and door frames, while still allowing for up to 180 degrees of swinging movement. They are sometimes also called bullet hinges, barrel hinges or lift-off hinges. Weld on hinges offer high control quality and are typically used in heavy duty industrial applications such as steel cabinets, electrical boxes, steel gates, machinery doors, transformer enclosures and tool boxes.
