SuvIRinimo Technologijos IR Brėžinių Skaitymo Testas

The biggest advantage of welding with a semi-automatic welding machine is the high welding speed. This means that the welding process can be completed quickly, saving time and increasing productivity.

The correct answer is "Suvirinimo procedūros aprašas" which translates to "Welding procedure description" in English. This answer is supported by the fact that the acronym "SPA" stands for "suvirinimo procedūros aprašas" in Lithuanian, which directly translates to "welding procedure description" in English.

The correct answer is 2D, which means that the TIG electrodes are galvanized using two electrode diameters, with a maximum diameter of 5mm. This implies that the TIG electrodes are coated with a layer of zinc or a zinc alloy, which provides corrosion resistance and prolongs the lifespan of the electrodes. Galvanizing the electrodes using two diameters ensures that a sufficient amount of coating is applied, while still maintaining the maximum diameter limit.

Deguonis sprogsta susilietus su tepalu. Tepalas yra degi medžiaga, todėl, susilietus su deguonimi, gali įvykti cheminė reakcija, kuri sukelia sprogimą. Vandeniu ir propanu deguonis nesprogsta, todėl jie netinkami atsakymai.

The given answer suggests that there are three different quality classes for threads: D, C, and B. The quality classes are likely ranked in descending order, with D being the lowest quality and B being the highest. The answer does not provide any information about the specific criteria or characteristics that determine the quality class of the threads.

The correct answer is "Žalias" (Green). In welding, a green tungsten electrode is commonly used when welding aluminum. This is because the green electrode is made of pure tungsten, which has a high melting point and good heat resistance. It is able to withstand the high temperatures required for welding aluminum without melting or deteriorating. Additionally, the green color helps to differentiate it from other types of tungsten electrodes used for different materials.

When copper comes into prolonged contact with acetylene, it forms an explosive compound.

The correct answer is 2400. This temperature is the burning temperature of propane-butane gas in oxygen.

The speed of wire feed in a welding machine depends on the current strength. The higher the current strength, the faster the wire feed will be.

The correct answer is 3100. This is the temperature at which acetylene gas burns in oxygen.

The thickness of the weld bead depends on the thickness of the material being welded. Thicker materials require a larger weld bead to ensure proper fusion and strength. Therefore, the correct answer is "Virinamos medžiagos storio" (The thickness of the material being welded).

The correct answer is "Valyti degiklio angalį" which means "Clean the burner chamber" in English. In MIG/MAG welding with automatic machines, it is necessary to regularly clean the burner chamber to ensure proper functioning and prevent any blockages or buildup of debris. This helps maintain the quality of the weld and prolong the lifespan of the equipment.

This sign, indicated by a red outline on a white background, prohibits drinking.

This Lithuanian question asks for the meaning of a certain symbol. The correct answer is "Bazinis paviršius," which translates to "Base surface" in English.

This sign indicates oxidizing substances.

Based on the given information, steel is classified into three categories based on carbon content. Non-alloy steels have a carbon content of up to 0.25%, medium alloy steels have a carbon content ranging from 0.25% to 0.6%, and high alloy steels have a carbon content greater than 0.6%.

TIG elektrodai yra užapvalinami kintamai srovei. This means that TIG electrodes are rounded off for variable current.

The correct answer is "b,a" because the question asks to write the letters "a" and "b" in lowercase as markings for "Amerikietiškas" and "Europietiškas" respectively.

The correct answer is the order in which the symbols should be placed in the given statement. The symbols represent different aspects of the welding process, such as the length of the weld, the type of weld, the quality class of the weld, etc. The correct order of the symbols is important for accurately describing the welding specifications.

The correct answer is 3,4,2,1. The chemical composition of the protective gas is 97% Ar + 3% CO2, which means that it consists of 97% argon and 3% carbon dioxide. Therefore, the correct order of the blanks is 3 (97% Ar + 3% CO2), 4 (100% CO2), 2 (80% Ar + 20% CO2), and 1 (100% Ar).

The correct answer includes all the welding parameters that need to be considered in order to obtain a good, high-quality, reliable weld. These parameters include the type of flux, electrode diameter, current type and polarity, current strength, electrode drying time, welding position, arc length, weld geometry, shade number of the protective shield glass, electrode movements during welding, and additional data for manual arc welding. Each of these parameters plays a crucial role in determining the quality and characteristics of the weld.

The correct answer is a combination of different welding processes according to LST EN ISO 4063. These processes include Acetylene-oxygen welding, Manual metal arc welding with covered electrodes, Tungsten inert gas welding, Flux-cored arc welding, Metal inert gas welding, Metal active gas welding, Submerged arc welding, Oxy-fuel gas cutting, and Plasma arc cutting.

The correct answer is Raudonas, Juodas.

The correct answer is z,a,s. This is because the question asks for the locations of a, z, and s, and the given answer correctly identifies these locations as z, a, and s.

The correct answer includes various types of internal welding defects such as cracks, lack of fusion, porosity, slag inclusions, oxide inclusions, and overheated weld. These defects can weaken the weld joint and affect its integrity, leading to potential failures or structural issues. It is important to identify and address these defects during welding inspections to ensure the quality and reliability of the welded components or structures.

The correct answer includes a list of various welding defects, such as lack of fusion, assembly errors, open pores, craters, excess weld metal, external oxidation, notches, and mismatch of weld size and shape. These defects can occur during the welding process and can negatively impact the quality and integrity of the weld joint.
