Hi steemit, how are you today? I hope you're all right. Today I will explain about Electrical Welding. Hopefully it will benefit many people.
Previously we have to know the preceding what is welding electricity? I am taking wikipedia referrals. According to Wikipedia, electric welding is by using electric arc flame that is directed to the metal surface to be joined. In parts affected by the electric arc will melt, so the electrode that produces an electric arc will melt at its end and propagate continuously until it runs out. (Source)
The connection of the two metals is done by attaching the two ends to be joined then the molten metal from the electrode will melt and fill the two metal gaps so that both are connected.
The electric arc welding machine can carry large electric current but with a safe voltage (less than 45 volts). The electric arc that occurs will generate high enough heat energy that will easily melt the affected metal. (source)
There are many things that can be done by using electric welding. Even as you know is that activities such as making boats, cars, bridges, fast pipes, and pipelines are all done by welding techniques sourced from electric welding.
In addition welding can also be used for a number of repairs, making the existing welding layer the reason a number of tools and welding can thicken the iron equipment that has worn out. By attaching the electrodes to the worn section.
Types of electric welds
Based on required pressure and volume. Electrical weld can be divided into three types, look like the following:
1. AC Flow Welding Machine (Back and forth)
This welding tool requires alternating current. Usually this current is generated by electric current generated by power plants, government electricity and other power plants.
In practice, this type of electric machine requires an alternating current electrical transformation. Why? Because the electric current like the source I mentioned above is typically high-voltage (source) of the current required this type of welding machine so it can set 55 to 80 volts. For household own electricity voltage usually run by 220 volts.
2. DC Current Laser Machine (Unidirectional)
DC current welding machine is though welding electric current with direct current, not back and forth. To get the voltage of this direct current is usually sourced from dynamo, electric motor, diesel motor and other movers.
3. Double Welding Machine (AC - DC)
This double welding machine can use both types of current, either handed or alternating current. The double welding machine has a single phase transformer and a rectifier or rectifier in one machine unit. (Source)
Most welding machines that work on various types of welding typically use double welding. Because it can adjust the voltage as needed. For example to weld thin plate, steel, often used the current size of 25 volts to 140 volts. In addition to working on thick welding workers can set the voltage of 60 to 300 volts. (Source)
That's the three types of electric welding machines that are often used. Of course with various advantages and disadvantages of each. If there is a writing error, please apply from my steemiter friend and I apologize. As human beings certainly have mistakes. Hopefully this article useful. Especially for those of you who like the world of welding.
