Argon-arc welding - what is it?

Let's start with what argon welding actually means. Nowadays argon is used in many production processes, including welding. Argon is essentially an inert gas. Due to this chemical inertness, argon does not react with the materials being welded, and acts as a protection against the effects of atmospheric gases, such as carbon dioxide, oxygen, nitrogen, water vapor and other substances that can affect the welding process. This is why it was given the name - argon welding .

Argon-arc welding is distinguished by the fact that its technology uses an electric arc and gas. The so-called electro-gas connection of metals occurs.

Argon-arc welding is usually divided into two types: automatic and manual . Each of these types of welding, in turn, can be used with either a consumable electrode or a non-consumable electrode. An electric arc melts the edges of the material being welded, connecting them. Argon itself protects the area of the parts being welded from harmful impurities and gases, i.e. it displaces oxygen from the working bath and the welding site itself is isolated from the influence of the external environment.

The main thing to remember is that argon is just a shielding gas for welding. And the welding itself is electric. Therefore, such welding is also called argon-arc welding, which is actually the same thing.

Automatic argon arc welding

Let's take a closer look at how automatic argon-arc welding with a consumable electrode .

During the welding process, the electrode (wire) is fed automatically. And on semi-automatic welding machines it’s exactly the same, the only difference is that there the wire is fed automatically, and everything else is done by a person manually.

The difference between automatic argon-arc welding with a non-consumable electrode is that tungsten or graphite is most often used as a non-consumable electrode, and argon is used as a shielding gas. All work is performed by robots programmed to perform specific actions.

Manual argon arc welding

Manual argon welding with a consumable electrode . Argon is used as a shielding gas. And a wire is also used as an electrode, which is fed automatically and is called an electrode.

In manual argon welding with a non-consumable electrode, the electrode does not melt, and the material for welding is supplied directly by the welder.

Drawing conclusions from the above, argon welding is a fairly simple method of joining metals, but it requires a lot of experience from the welder in order to really perform high-quality welding work on various welding equipment with various metals.

Features of welding method 111

Method 111 welding is also known as the manual arc welding method. They come in two types: using a consumable and non-consumable electrode.

The consumable electrode welding method is the main method for manual welding. To implement this, a piece electrode coated with coating is used. An electric arc is excited between the consumable electrode and the product, which heats and melts the edges of the product and the electrode. The resulting bath of liquid metal mixture cools and forms a seam.

The welding method with a non-consumable electrode is similar to the previous one. The only difference is that when an arc is formed, only the product melts along the edge. Next, the metal, as in the previous method, hardens, forming a seam. This method is used for welding work with non-ferrous metals and alloys.

Welding methods in Poland - description

Description of method 135 – MAG welding

The MAG (Metal Active Gas) method is a welding technology that uses a chemically active gas, such as CO2, as a shielding gas. The molten electrode is a solid or cored wire, which also acts as a binder. In MAG welding processes, carbon dioxide or gas mixtures are used as shielding gases, which include: argon, oxygen, carbon dioxide and others.

Application of MAG welding method. The MAG method is used for welding stainless steel, unalloyed steel, low alloy steel and high alloy steel. Welders with the MAG welding method are the most in demand on the labor market in Poland and the EU. Other welding methods are less in demand in Poland.

What is this concept of semi-automatic welding?

You most likely heard or saw an advertisement that a welder who welds semi-automatically is required. So, if those intermediaries who wrote that ad knew the basic concepts, they could have written more accurately. Since the concepts of migmag welding and semi-automatic welding are colloquial names for the welding process, both mig and mag. And this concept suggests that MIG/MAG welding is universal.

Characteristics of the MIG/MAG welding method

Advantages of the MIG/MAG welding method: + universal method - you can weld various metals and their alloys in all spatial positions; + high welding efficiency - much higher than coated electrodes; + relatively low cost of welding materials - the total cost is approximately 20% lower than the cost of welding with coated electrodes; + good quality of welds; + the ability to mechanize and automate the method.

Disadvantages of the migmag welding method, also known as semi-automatic welding: - the quality of the weld largely depends on the qualifications of the welder, - relatively high costs for the purchase of devices and equipment, - mag welding is characterized by a greater tendency to form adhesion and porosity of the seams.

Description of gas welding method 311

Method 311 welding process - gas welding: This welding method involves melting the edges of the metals being joined through heating by a flame of burning combustible gas in an atmosphere of supplied oxygen. Acetylene is predominantly used as a flammable gas.

Applications of Gas Welding: Gas welding is used for all types of steel and non-ferrous metals. Gas welding is less popular in Poland than in Ukraine. We know, since 90% of us are welders from Ukraine. If you want to find a high-paying job in Europe, then it’s worth developing and learning additional methods. And we advise you with method 135 (MAG).

Covered electrode arc welding, method 111

Description of the Welding Process by Method 111 This welding method consists of melting metals at their joint through an electric arc formed between the welded element and the coated electrode. For arc welding, direct or alternating current is used, but the former is more favorable.

Sheathed electrodes are used for welding:

acidic (A);
rutile (g);
alkaline (B);
rutile acid (RA);
cellulose (C);
rutile cellulose (RC);
and another.

Applications Covered electrode welding is applicable to all unalloyed, low alloyed and high alloyed steels, cast steels, cast irons and non-ferrous metals.

Welding method MIG 131

Description of work using the MIG welding method: The MIG (Metal Inert Gas) method is welding with a molten electrode in an environment of protective inert gases. Since in the MAG method, the wire acts as a binder (the so-called electrode wire). During the welding process, shielding gases such as argon and helium and their mixtures are used.

Application of MIG welding technology: The MIG method is used for welding non-ferrous metals. In most cases these are aluminum alloys.

Welding inspector

A welding inspector
is an inspector who carries out control from the storage of welding and basic materials to control of non-destructive testing on a finished welded product.
I have prepared a whole series of articles for you in which I tried to briefly outline the essence of the task of a welding inspector. In this article we will get acquainted with the classification of the main welding methods, the principles of the main methods of electric arc fusion welding and the international codes and abbreviations for the main welding processes. Classification of main welding methods

Welding is one of the processes of joining materials. As indicated below, all existing welding methods can be divided into two main groups:

fusion welding: gas, electric arc, electroslag, electron beam, laser, etc.;
pressure welding: contact, friction, diffusion, ultrasound, etc.

Fusion welding

carried out by melting the edges of the parts being connected and the filler material to form a common weld pool. The welded joint is formed without external forces.

Pressure welding

carried out by establishing interatomic bonds between the connected parts using external forces.

Principles of basic methods of electric arc fusion welding

Technology of mechanized consumable electrode welding in active gases and mixtures (MG)

9.5.1 Mechanized welding with a solid wire in a carbon dioxide environment with controlled transfer of droplets through the arc gap (STT, UKP, VKZ) is implemented using specialized welding current sources that provide a change in the welding current and voltage according to a specific algorithm and is intended for welding the root layer of welded connections of pipes with a diameter from 100 to 1220 mm with wall thicknesses from 3 to 32 mm. The algorithm for changing the welding current determines the name of the process; currently the most widespread processes are:

The equipment includes:

— special power source;

— wire feed mechanism;

- welding torch;

- coaxial cable;

— gas cylinder with reducer, flow meter and gas heater;

protective tent.

9.4.3.1 100% premium grade carbon dioxide in accordance with GOST 8050 should be used as a shielding gas.

9.4.3.2 Welding is carried out using a top-down method using direct current of reverse polarity.

9.4.3.3 The welding method can be used to perform the root layer of a weld during special welding operations - welding joints of different thicknesses, overlaps, pipe-fitting connections and pipe-stop valves.

Technology of mechanized welding with solid wire in a carbon dioxide environment using the STT method

9.5.2.1 Gas consumption when welding should be 10-16 l/min.

9.5.2.2 The stickout of the electrode wire during welding should be from 10 to 15 mm. An overhang of up to 20 mm is allowed.

9.5.2.3 In the 0.00-1.00 (1.30) hour position, welding is carried out with slight transverse vibrations without delay at the edges. In position 1.00 (1.30) - 6.00 o'clock welding is carried out without transverse vibrations.
