Work as a welder using method 111 in Poland

Nowadays, getting a well-paid job abroad is not so difficult.
Every year more and more people want to find a job in Europe, but this does not mean that there are fewer vacancies and the demand for qualified personnel is steadily growing. The most favorable country for working and living is Poland. Ukrainians are attracted by the short distance from home, the loyalty of employers, high earnings and comfortable living conditions.

To set off towards financial independence, stability and new prospects, you need to follow a few simple steps. The first is to contact a company for employment abroad.

The demand for welders in Poland is quite high. For specialists in this profession, there is a large selection of vacancies in different fields: equipment, assembly, cars. That is, you can choose a job according to your preferences, explore all the options and possibilities, identify the advantages and choose the best offer from the employer

The most popular welding methods in Poland

Let’s say from our own experience, since we are an agency that employs on average 20 welders for work in Poland every month directly to the employer and to our agency. According to the welding method in Poland, the most popular method is 135. We already wrote this in our previous article “Welder in Poland. What do employers offer and for what? Interview".

You can see this with a clear example by going to our vacancies section for welders. Most of them are based on the 135 method.

We advise welders to also master other methods. This makes you a rarer specialist, allowing you to negotiate the best rate for yourself. Why are we sure of this? Since the employer spends time and money looking for a welder. Plus the fear that a good specialist might come, but he drinks. We wrote this for a reason. Employers, when they give us an order to recruit workers, emphasize that the welder does not drink or appear drunk at work.

Why should you contact Gvardia Sp. z oo?

Guardia Sp. z oo is an agency that provides employment to its clients in European countries, mainly in Poland. The company works without intermediaries, directly with employers. All vacancies presented on the site are relevant and require official registration with the provision of all necessary documents.

In total, there are three types of documents of this type in the country and they spell out in great detail the rights and obligations of the parties, indicating the presence of social services. package for the employee, namely paid sick leave and vacations.

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 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.

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.
