Welding electrode E7018 is a term that describes the electrode's tensile strength, welding position, flux coating and current. E7018 electrodes are used in manual metal arc or MMA welding.
In MMA welding, an arc is struck between the electrode and the object in question. The electrode and metal object melt and form a solid on cooling. As it melts, the central electrode acts as the filler material to create the new, seamless solid mass. As such, it is a consumable material.
The number code of the electrode is known as its AWS, or American Welding Society, name. The digits all have a specific meaning.
Use of the correct electrode of the right size and at the correct angle is essential to producing a successful weld. MMA welding is one of the most widely used welding techniques and is often the preferred method for carbon steels.Learn More
The difference between MIG and TIG welding is that the MIG welding technique feeds a continuous spool of wire into the melding puddle while TIG uses long welding rods to accomplish a similar task. The MIG welding process is done with metal inert gas. The TIG welding process is done with tungsten inert gas.Full Answer >
There are many websites that offer instruction, information and resources for learning how to weld as a hobby. For example, the American Welding Society is an international membership organization whose website offers a searchable database of welding schools located all over the world.Full Answer >
To begin stick welding, take care of basic welding safety, prepare the joint, and make the appropriate rod selection. Follow the manufacturer’s recommendations when selecting your rod.Full Answer >
The most widely used types of welding are stick or arc, gas metal arc, gas tungsten arc, plasma arc, shielded-metal arc, submerged arc, electroslag, flux-cored, metal inert gas and tungsten inert gas. The type of welding used usually depends on the thickness and form of the material.Full Answer >
