Welding is an amusing job. Especially when you love welding with core wires, it becomes necessary for you to check 30 vs 35 flux core wires to decide which one is better for your work.
Choosing the wrong core wire can make you face problems leading to poor appearance, burnouts, and even explosions. So, let the frustration out and gather learnings about 30 and 35 flux core wire carefully.
First of all, let’s check out the comparison table to get an overview of the two flux core:
Comparison Table On 30 vs 35 Flux Core Wires
|Topic||30 flux core||35 flux core|
|Material||Carbon steel or mild steel||Carbon steel or mild steel|
|Volt range||17-20 volt||18-24 volt|
|Use||Thin metals||Thick metals|
|Amount of flux||Less||More|
|Stick- length||Comparably short||Comparably long|
|Surface appearance||Cleaner and smoother||A bit messy|
30 Flux Core Wire:
The core wire 30 is basically a 0.030-inch diameter wire which is used to weld thin metals and to maintain rusty thin materials. A 0.030-inch core wire is perfect for bringing a smooth and clean welding appearance, Additionally, The welding can be done in all positions including vertical.
Let’s delve deeper by acknowledging some pros and cons of a 0.030” flux core wire:
35 Flux Core Wire:
The core wire 35 is basically a 0.035-inch diameter-based wire which is used to weld comparably thicker metals at a higher level of heat. However, a 0.035-inch core wire is not perfect for bringing a smooth appearance, but it’s an essential core wire in joining metal gaps. Moreover, it is also an all-position welding wire.
Let’s find out some of its pros and cons:
However, there are a lot of similarities and differences that come in while doing an analysis of these two. Let’s find out the similarities first!
Similarities between 30 vs 35 flux core wire
The 30 and 35 flux core wires are both made of flux-based core wires with slightly different diameters. The 30 flux core represents a 0.030-inch diameter wire and 35 means a diameter of 0.035 inches. They are used in welding different kinds of materials based on their capabilities. Although, they both are made of carbon steel or mild steel.
In welding jobs, whether it’s for home or industrial work, the position becomes a huge deal. It’s because all position welding wire has a high demand. Hence, both 30 and 35-flux core wires fulfill most of the welding criteria as they work in all positions.
In the flux core wire, the flux is a substance of deoxidizer that allows welders to weld dirty metals in windy conditions. Flux generates shielding gases that protect melted material from oxygen and nitrogen while stabilizing the arc. Also, it collects all slags from the bead before it gets stuck to the cooled metal.
All your doubts will come clean while having knowledge of the Difference between 30 and core and 35 core wires. Let’s have look at:
Differences between 30 vs 35 flux core wire
The main difference comes in the diameter of both wires. The 30 and 35 flux core wires were practically named, indicating the diameter of 0.030 and 0.035 in the unit “inch”.
Appearance leaves a huge impact on welders as they want to see is a smooth and nicely finished weld appearance in the end. However, in the case of 35 flux core wire, you will get a spatter finishing due to its extra amount of flux content.
In the case of the 0.030-inch core wire, it conducts on low voltage better and can do fewer voltage fluctuations. The 0.030-inch wire is also good for welding in small corners because it deposits less metal.
Conversely, a 0.035-inch core wire takes up more voltage. Additionally, it can lead to a shortening of the arc cone which can conduct burnouts or poor penetration.
Which flux core should you choose between 30 and 35 core wire?
The usage of core wires depends on the user itself. If you want to perform welding on thin metals in cool air conditions or household jobs, the 30 flux wire is perfect.
On the other hand, if you want to weld in thicker metals for industrial jobs, then a 35-core wire is better than 30 core wire in general. However, a person can also vary their choice based on power or voltage range preferences.
Frequently Asked Questions
Still, have questions regarding the 30 and 35 flux core wire? Here’s another quick solution for you. You can gather more useful information from the questions asked by some curious minds.
To weld thin metals, you can choose 0.030 flux core wires. But for welding thicker metals, you should choose 0.035-inch flux core wires to avoid dangers.
The 0.035 flux core wire is perfect for gap filling as they tend to have more flux contents than 0.030-inch wires. 0.035-inch wires deposit more metals and make for a better choice when welding gaps.
It’s very risky to use a tip of 0.035 wire in a 0.030 wire as it can cause serious damage to the metal as well as to the environment by creating burnouts and explosions.
Observing the 30 vs 35 flux core wire, we can conclude both types of core wire are beneficial for you. Considering all pros and cons, you can easily justify the need as well.
