A guid to weld on bullet hinges

Weld-on hinges are also known as bullet hinges due to the tapered shape of the barrel's tip. Which leads to another name they're known by: barrel hinges.While the hinge's barrel resembles the look of a bullet, it's not just its shape that differentiates it from other hinges. It's how it's fastened. While traditional hinges are secured with bolts or screws, weld-on hinges – as the name implies, are installed by welding.

Heavy-duty weld-on hinges, also called heavy-duty barrel hinges and heavy-duty weld-on gate hinges, are another option for exceptional loads. Some weld-on hinges come with grease nipples, which allows the hinge pin to be easily lubricated – an ideal mechanism for heavy doors. The example to the right is a weld-on hinge with a grease nipple, which protrudes from the tip.

Is a bullet-hinge installation right for you?

You can install a weld-on bullet hinge anywhere you like, at any angle needed. All that’s necessary is that the metal surface supports welding. There are two considerations for bullet hinge, however:

1. Welding torch needed: Welding is a fabrication process that fuses two metals together with heat. You’ll need a welding torch to secure the hinges.

2. Doesn’t work with wood: Bullet hinge can’t be welded onto wooden structures. If you’re working with wood, use traditional hinges with through holes and threaded fasteners.

The most popular bullet hinge materials for weld-on hinges are:

1. Steel: Strong and durable, steel bullet hinges are suited for high-stress applications. Weld-on steel hinges are available with a brass or steel pin.

2. Stainless steel: Stainless-steel barrel hinges offer a high degree of corrosion resistance for harsh environments. Stainless-steel weldable hinges with a stainless-steel pin are grade 304.

3. Aluminium: Weld-on aluminium hinges are lightweight without sacrificing durability and strength. Excellent corrosion resistance. Available with a stainless-steel pin.

How to Installing bullet hinges:

Bullet hinge sizes vary, so you shouldn’t have any problems finding what you need. Your next concern is how to install a bullet hinge. For our purposes, we’re going to explain the process as it regards a gate.

If you’re new to welding, you’ll need to understand tack welding, which are very small welds meant to temporarily bond metals. They enable you to maintain the joint gap while holding the hinge in place. It also shows you if your hinge is aligned properly.
