Industrial training for an electric and gas welder is practice, but it is far from it if the theory has not been mastered. Where and what is taught, and most importantly, what is the essence of training for electric and gas welders?
Welding is one of the most common technical method unite various materials, mainly metal, for creating various products, metal structures and equipment. Metal systems that have been welded are much stronger, smaller in volume and less labor intensive to produce than cast, forged or riveted structures.
Therefore, training to become an electric and gas welder is training in a specialty that is necessary in the modern world. In industry and construction sites, quick installations that connect the necessary metal materials are always welcome.
People who have completed training courses for electric and gas welders in Moscow and have passed certification work in production and construction sites in the capital and throughout the country. Many specialists find their place abroad.
Where can I get training as an electric gas welder?
First you need to decide on the place where classes in this profession are held. These could be special preparatory training courses for electric and gas welders in Moscow and throughout Russia, or they could be vocational educational institutions such as a college, vocational school or lyceum. Getting there is quite easy. You just need to pay attention to the pedagogical approach, the opinions of people who have graduated from such educational institutions, as well as the certificate that is issued after completion of studies. Be careful that this certificate or evidence is valid and recognized in Russia.
During training to become an electric and gas welder, a candidate welder acquires the necessary knowledge that can help him achieve his specialty. The most important in training takes the place of passing practical tests. This is a big advantage of training to become an electric and gas welder in Moscow. There are more facilities in the capital where you can go to practice and more employment options. But in the regions of the country it is quite possible to find a place for internship.
By and large, skilled welding masters recruit inexperienced welders as apprentices. All skills, all knowledge and features can only be acquired from a specialist. No amount of text materials and video reviews can bring a person the most basic thing - a skill. Therefore, a place for practical training should be sought already during the training period.
What is taught in courses for electric and gas welders?

Required documents
If you purchased a welding machine intended for work using the MMA (Manual Metal Arc)- manual electric arc welding with a coated piece electrode, but you don’t know how to get started, you should carefully read the material below.
1. Network connection.
Check out technical characteristics Your welding machine for compliance with the electrical network to which it is planned to be connected. The supply voltage and number of phases of the device must correspond to the same parameters of the electrical network. Now there is a large selection of welding machines that can operate from both 220V and 380V networks. Such devices have a network type switch that must be moved to the desired position before connecting to the power supply. The second important parameter is the power consumed welding machine. If the rating of the circuit breaker installed in the electrical network you are using is less than that required for the power consumption of the device, the circuit breaker will turn off the power and will not allow you to use the welding machine.
2. Select an electrode
Electrodes used in manual arc welding consist of a metal rod with special coating. The material of the electrode rod must be similar to the material of the parts being welded. The diameter of the electrode is selected depending on the thickness of the product being welded.
3. Select the welding current value
The amount of welding current primarily depends on the diameter of the selected electrode and can be calculated using a simplified formula: 35-40A of current is required per 1 mm of electrode diameter, i.e. If you take a welding electrode with a diameter of 3mm, then for operation you will need a current of 105-120A.
Important: when performing welding work with vertical and ceiling seams, the current must be reduced by 10-20%.
4. Light the welding arc and cook
After setting the required amperage, you can proceed directly to welding.
Ignition (excitation) of the welding arc
First way: arc ignition by touch. The electrode is smoothly lowered perpendicular to the surface of the part, easily touches the surface at the start of the weld and is pulled up leaving a small gap that ensures stable arc burning.
Second way: ignition of the arc by striking. In this case, the process of exciting the arc is reminiscent of the process of lighting a match, in which the electrode moves tangentially to the surface of the metal with a light touch and fixation of the optimal gap.
As the electrode burns out, you must try to maintain the selected gap and at the same time move the electrode along the line of connection of the parts. If the electrode sticks, it is necessary to vigorously shake it, tear it away from the metal and re-ignite the arc. To obtain a high-quality welded joint, it is necessary to acquire a solid skill in maintaining a stable arc with a gap of 3-5 mm between the electrode and the part.
5. Correct movement of the electrode
Correctly guide the electrode as shown in the figure, and not in a straight line. Basic movements:
1.Progressive- vertically along the electrode axis to maintain a constant arc length and electrode melting rate.
2.Rectilinear- horizontal along the axis of the seam to maintain optimal welding speed ensuring high-quality formation of the welded joint.
3. Oscillatory- horizontal across the axis of the seam to improve heating of the edges. the length of the transverse movement can be up to 4 electrode diameters, which allows you to obtain a uniform seam of the appropriate width. This type of movement can be eliminated when welding thin sheets of metal or when making the first seam in a multi-layer weld.
Types of oscillatory movements
 | Used to produce a weld with surfacing beads when welding parts into a butt without chamfering on the edges, in the lower position with sufficient thickness of the part. | |
 | Used to produce butt fillet welds on chamfered edges in any position using electrodes with a diameter of less than 4 mm. | |
 | For making vertical and ceiling joints with a convex profile. | |
 | For making fillet and butt welds in any spatial position on chamfered edges. Provides excellent penetration of the root seam. | |
 | It is used when guaranteed penetration of the root weld on thick-walled parts is necessary. | |
 | Used when welding products made of high-alloy steels to provide enhanced heating. The movement is delayed in extreme positions to prevent burning in the center or leakage of metal when working with vertical seams. |
If the electrode moves correctly, the seam will be stronger, with smooth boundaries and minimum quantity slag inside also improves the penetration of the edges and facilitates the separation of the slag crust.
Classification of the position of the weld in space
To acquire stable skills, it is best to learn to work with piece electrodes with a diameter of 2.6-3 mm. These electrodes are most often used for welding at home. The most common electrodes are rutile coated electrodes, which are also good for inexperienced welders. To ensure more comfortable ignition of the arc and obtain high quality weld, the electrodes must be calcined or dried at a temperature of 150-200°C for 1-2 hours (more accurate data for electrodes with various types coatings are indicated on their packaging).
