Welding is a complex procedure that requires adequate knowledge and experience. Welding machines are available that make it a convenient process but still is a complicated task. So you need to be experienced in the welding process, even if you perform it at a smaller scale.
Like other procedures, welding requires some essential things that make it possible to provide the necessary results. So every welder must choose the welding material according to the task they want to perform.
However, we will discuss the five welding essentials that are required for a proper welding procedure.
Six essentials for welding procedure
Welding has three different types that require a different kind of material according to welding point and position. Here we will discuss the welding essentials in general so that it will provide the basic idea.
1) Electrode size
The electrode is the key to the welding process. So it must be according to the correct size and type. Some factors help choose the appropriate size of electrodes like welding, position, joint preparation, electrode ability to deal with the current, deposition efficiency, and many more. Moreover, the metal that needs welding also affects the size of the electrode. It must have the ability to penetrate metal even if it has heavy mass and maintains its original shape after heat stress. All these factors decide the size of the welding electrode according to the task, so you need to keep them in mind.
2) Correct current
The welding procedure requires a suitable current for the appropriate weld. If there is too high or low current in welding material, you will get a poor welding appearance. The high current causes the electrode to melt, the metal to pass, and the molten pool becomes large and uneven. Whereas the low current is not enough to melt the metal, and the molten pool becomes small or piles up, it also looks irregular. It is essential to provide a suitable current to the welding electrode for the desired weld.
3) Arc length and voltage
Arc is the point where metal requires welding. If the arc is long and the voltage is high, then the electrode’s electrode melts in globules that create spattered and irregular welding beats. But if the arc is short and voltage is also low, it doesn’t have the required amount of heat to melt the base metal, and the electrode becomes sticky to the welding point. Low voltage also creates uneven beads of welding.
4) Electrode angle
Electrode angle also has key importance in the welding procedure. The position of the metal and the electrode angle depends on each other. If you want to create the fillet weld, ensure that the welding electrode and metal pieces are perpendiculars. If an undercut appears during welding, lower or direct the angle of the arc and electrode.
Speed of moving the welding electrode on metal pieces also has supreme importance. If your speed is fast, then the pool doesn’t last long, entrap impurities and gas. High speed produces the narrow beads along with ripple points. If the welding speed is low, then molten metal piles up and create dense welding beads.
Last but not least – welding is a dangerous process and injuries are common. Make sure that you always have a welding helmet on (they are not that expensive these days as you can see here: https://www.weldingsuperstore.com.au/welding-helmets ), jackets, gloves and boots are also very important.
