용접 초보자도 용접 잘하는 법.ㅡ 첫번째 이야기. 노하우 꿀팁 방출.(How to do welding even for beginners.)

용접의 기본원리와 용접 잘할수 있는 기본적인 노하우와 팁을

실전에 앞서 나름대로 풀어 보겠습니다.

기본적인 상식을 가지고 임하시면 실전에 있어서 그나마 나은

결과물을 얻으실 수 있습니다.


용접뿐만 아니라 모든 현장일을 처음부터 잘하시는 분은 없습니다.

하나하나 차근차근 경험을 쌓고 나아가서 자기것으로 만드는 것은

본인 의지와 노력에 달렸습니다. 한땀한땀 용접할때 마다 생각하고

생각하면 좀더 나은 방법이 나타날 것입니다.

오롯이 집중에 집중을 하시고 경험을 쌓는다면 실력이 쑥쑥...

자랄것입니다.

The basic principles of welding and the basic know-how and tips for good welding

I will solve it in my own way before the actual game.

If you work with basic common sense,

You can get the result.


No one is good at doing all of the field work, not just welding.

One by one, one by one is to gain experience and make it yours

It depends on your will and your efforts. I think every time I weld a sweat

Think about it, and a better way will emerge.

If you focus on your concentration and gain experience, your skills will grow...

Will grow

The American Welding Society (AWS) numbering system can tell a welder quite a bit about a specific stick electrode including what application it works best in and how it should be used to maximize performance. With that in mind, let's take a look at the system and how it works.

The prefix "E" designates an arc welding electrode. The first two digits of a 4-digit number and the first three digits of 5-digit number indicate minimum tensile strength. For example, E6010 is a 60,000 psi tensile strength electrode while E10018 designates a 100,000 psi tensile strength electrode.

The next to last digit indicates position. The "1" designates an all position electrode, "2" is for flat and horizontal positions only; while "4" indicates an electrode that can be used for flat, horizontal, vertical down and overhead. The last 2 digits taken together indicate the type of coating and the correct polarity or current to use. See chart below:



Digit Type of Coating Welding Current
0 High cellulose sodium DC+
1 High cellulose potassium AC, DC+ or DC-
2 High titania sodium AC, DC-
3 High titania potassium AC, DC+
4 Iron powder, titania AC, DC+ or DC-
5 Low hydrogen sodium DC+
6 Low hydrogen potassium AC, DC+
7 High iron oxide, iron powder AC, DC+ or DC-
8 Low hydrogen potassium, iron powder AC, DC+ or DC-


As a welder, there are certain electrodes that you will most likely see and use time and time again as you go about your daily operations. A DC machine produces a smoother arc. DC rated electrodes will only run on a DC welding machine. Electrodes which are rated for AC welding are more forgiving and can also be used with a DC machine. Here are some of the most common electrodes and how they are typically used:

E6013
This all-position, AC electrode is used for welding clean, new sheet metal. Its soft arc has minimal spatter, moderate penetration and an easy-to-clean slag. Lincoln Fleetweld® 37 is most common of this type.

E7018
A low-hydrogen, usually DC, all-position electrode used when quality is an issue or for hard-to-weld metals. It has the capability of producing more uniform weld metal, which has better impact properties at temperatures below zero. The Lincoln products are typically Jetweld® LH-78 or our new Excalibur® 7018.

The coatings of welding electrodes for welding mild and low alloy steels may have from 6 to 12 ingredients, which includes:

Cellulose – to provide a gaseous shield with a reducing agent in which the gas shield surrounding the arc is produced by the disintegration of cellulose
Metal carbonates – to adjust the basicity of the slag and to provide a reducing atmosphere
Titanium dioxide – to help form a highly fluid, but quick-freezing slag and to provide ionization for the arc
Ferromanganese \u0026 ferrosilicon – to help deoxidize the molten weld metal and to supplement the manganese content and silicon content of the deposited weld metal
Clays \u0026 gums – to provide elasticity for extruding the plastic coating material and to help provide strength to the coating
Calcium fluoride – to provide shielding gas to protect the arc, adjust the basicity of the slag, and provide fluidity and solubility of the metal oxides
Mineral silicates – to provide slag and give strength to the electrode covering
Alloying metals including nickel, molybdenum, and chromium – to provide alloy content to the deposited weld metal
Iron or manganese oxide – to adjust the fluidity and properties of the slag and to help stabilize the arc
Iron powder – to increase the productivity by providing extra metal to be deposited in the weld.
