Why does my welding rod keep sticking?
Whenever do you observe your rod to hold with metal during welding?
What would be the reason for it? And how to get rid.
Welding rod usually is an electrode or a filling metal which used to join two or more pieces of metal by a heating process.

Different welding rods used to weld metals, according to the nature of welding and chemistry of metal. There are two main types of welding rods
- The consumable
- The non-consumable.
The consumable rods are consumed or used in the process of welding. While l, the non-consumable rods act as adjuvant or not lose their bodies in the whole process of welding.
A most common problem during the process of welding is the stickiness of welding electrodes. There are many reasons to stick to the welding rods. Here we are going to a few describe below:
Size of arc also an obvious key point that involves for sticking of the welding rod.
It’s a reason for the stick rod with the base metal.
If you bring the rod too to the base metal, it will bond to metal.
Hence, maintaining the distance between electrode and base metal can prevent wires from sticking the metal.
Selection of welding rod
Different welding rods manufactured for various tasks. Some specialized welding rods for AC or DC. At the same time, some perform their functionality at both direct current and also on alternating current. Be aware of the selection for the welding rod by considering their required flow. If a welder didn't select the right welding rod, he should experience the electrode's sticking.
The diameter of the welding rod
Electrode diameter also a reason for the sticking of the welding rod. The primary phenomenon for the consumable welding "Melting of electrode flux quite before, melting of base metal, so when the base metal melts the welding rod materials spot on the base and fills the broken parts. If you took a welding rod of thick diameter, on thin base metal, it causes sticking. The main reason for sticking is the high current welding rod flow and a higher melting point of the welding rod.
If welding rod melts after the melting of base metal, it causes sticking.
If the base metal's surface is too oily or rusty, it will cause problem while welding. The rods stick with metal when a welder applies an arc.
Suppose resistance increases. It creates a decrease in current flow.
When the arc is using at rusty base metal, current flow also disturbs the quality of amperage, which causes the improper flow of amperes during the welding process.
If current amperes didn’t make a connection flow, sticking also causes.
So, the poor rod quality or the inferior surface of base metal cause problems of rods stickiness during welding. Choose the excellent condition of rod and clean the surface of metal before welding.
Unstable open circuit voltage:
Proper welding needs stable open-circuit energy, as open-circuit voltage maintains the arc. If a welder has struggled in connection, you face the problem of low open current voltage. Current flow, if not stabilized, surely electrodes keep sticking with metal.
Welding proceeds when the tip of the electrode melts and fills the broken area of two metals.
And a measured current is necessary to melt the tip of the wire. If there is an insufficient provision of flow, then the tip of the rod will not dissolve properly.
Hence it will cause to stick the rod with the base metal. Before picking your welding torch, adjust the current to ensure the sufficient supply of current for the melting of the electrode’s tip.
Rough flux quality:
If we observe the composition of the welding rod, it noticed that specific material coated over the rod. This coating act as a filler agent between two metals. The melting point of the flux or coated material should be less than the melting point of base metals. If flux quality is poor, it will fall off in the shape of the melted chunk, and the rod will stick with the base metal.
The best quality flux liquefies when the base metal starts melting. Using the excellent quality of flux can minimize the risk of the stickiness of the electrode.
If you are worried about the sticking problem and question, arise in your mind like other welders that, why does my welding rod keep sticking? This article may help you understand the nature of the problem. And the preventions are also discussed above. A good welder must diagnose and fix the bugs in its work. Rod sticking problems can sort out by providing proper current and voltage. Also, by using good quality of flux. If you are a beginner and continuously face the sticking issue, this article is beneficial for you. Have the best start-up!
