A Guide to Gap Electrodes

Are you looking to learn a bit about gap electrodes? Perhaps you're new to micro gap welding and wanting to know if you can benefit from purchasing one. Or maybe you're just curious as to their applications. Whatever the case, here's a quick guide to help you understand gap electrodes.

Gap electrodes-what they are and how they're made

Gap electrodes are tips you use in welding. Also called "parallel GE," these tips comprise two separate halves. Within the electrode holder, each half is usually held carefully in place in left and right positions. The halves of the electrode may be:

• Bonded - In many cases, your electrode holder may require an electrode that is bonded together. In this situation, the electrode gap is predetermined, meaning you have no room to customize the gap. The two halves are bound together by an adhesive layer that serves as an insulator.

• Free standing - In other cases, you may purchase a welder that has a specially designed electrode holder. In this case you are able to customize the distance between each half of the electrode, allowing for more versatility. It works by utilizing free floating gap electrodes.

Which is better? Well it depends on your specific needs. Talk to a professional supplier to discuss what's right for your applications.

How different GE welding techniques work

Gap electrodes are especially advantageous in situations where you're welding a piece that has insulation on one side. In this situation, the welding current will:

1. Travel down one half of the electrode

2. Go through the materials being welded

3. Rise up the other half of the electrode

This is known as a series configuration.

Step welds are a bit different. Each half of the electrode touches a different material, allowing the weld current to pass over the material interface.

When you use parallel gap electrodes, each half targets the piece from matching directions. Regardless of which form of welding you're attempting, there's a GE to fit your individual need.

Choosing a supplier

If you're in need of gap electrodes, it's crucial that you choose the right supplier. That said, you need to know what to look for in a welding supplies provider. Make sure the company:

• Has been around for awhile. You don't want to deal with a fly-by-night organization.

• Is knowledgeable. You need someone who can answer all of your product and application related questions.

• Is reasonable with prices. There are a lot of people out there who will try to rob you blind. Don't fall for it. Only go with a company who has competitive prices for GE.

• Offers other services. If you're in the market for GE, chances are you'll need other services along the way. Choose a company that also offers things such as CNC Milling Services, CNC Machine Shops and CNC Lathe Turning. That way, one company can handle all of your needs.
