Metal welding methods: which is better to use?

Krympress reports:

Metal welding is an important process that is widely used in various industries and construction. There are many welding methods, each of which has its own unique features and advantages. In this article, we will consider the main types of metal welding, their technology and area of ​​application.

Arc welding

Oak welding is one of the most common metal welding methods and includes several subspecies.

Manual arc welding (mma)

Manual arc welding, also known as welding with a piece electrode, is used to connect metal parts using an electric arc.

Advantages:

• High flexibility.

• The possibility of welding of various types of metals.

Flaws:

• Requires high qualifications of the welder.

• Special skills are needed.

Arc welding among protective gases (mig/mag)

Oak welding among protective gases is used to welding various metals, including steel, aluminum and stainless steel. In this method, an electric arc is used, which is formed between the electrode and the material welded.

Advantages:

• High quality weld.

• Prevention of oxidation thanks to protective gases.

Flaws:

• The need to use protective gases.

• The complexity of the process requires high qualifications.

Argonoduga welding (TIG)

Argonoduga welding is used to connect metals with high accuracy and quality. This method is especially suitable for welding metals such as aluminum, magnesium and stainless steel. For example, Welding aluminum argon Requires the use of the inert gas of the Argon, which protects the welded seam from oxidation and provides excellent connection quality.

Advantages:

• High accuracy.

• Excellent connection quality.

Flaws:

• The complexity of the process.

• High costs.

Gas welding

Gas welding includes several methods, the main of which is acetylene acid welding.

Acetylene acid welding

Acetylene acid welding is used to connect metal parts using a flame formed as a result of combustion of acetylene and oxygen. This method is especially effective for welding thin metal sheets and pipes. Gas welding can also be used for soldering when special recycled materials are used.

Advantages:

• High temperature.

• Suitable for welding thin metal sheets and pipes.

Flaws:

• The danger of using combustible gases.

• Special precautions are required.

Electric lane welding

Electro -lane welding is used to connect thick metal parts, such as steel plates and beams. The principle of operation of electrical welding is based on the use of heat released during the passage of electric current through the slag.

Advantages:

• High performance.

• The possibility of welding of large and thick details.

Flaws:

• Requires specialized equipment.

• Experienced welders are needed.

Plasma welding

Plasma welding is a method in which a plasma arc is used to melting and connecting metals. This method is characterized by high temperature and accuracy, which makes it ideal for welding thin and complex products.

Advantages:

• High temperature.

• The possibility of welding of various metals.

Flaws:

• Requires the use of specialized equipment.

• Difficulty for mastering.

Laser welding

Laser welding uses a concentrated laser beam to melting and connecting metal parts.

Advantages:

• High accuracy.

• Minimum thermal impact on the material.

Flaws:

• High equipment costs.

• The need for specialized equipment.

If you need Order laser weldingit is important to take into account the type of metal and the required accuracy of the connection.

Point welding

Point welding is used to connect thin metal sheets using spot heating and pressure. This method is widely used in the production of cars, household appliances and other products where a strong and durable connection is required.

Advantages:

• High performance.

• The possibility of automation of the process.

Flaws:

• Restrictions on use for thick metals.

• Requires specialized equipment.

Examples of application of each method

Metal welding methods are widely used in various industries:

Industrial applications:

• Automotive industry: welding of body parts and structural elements.

• Aircraft construction: the production of components for aviation equipment.

• Shipbuilding: welding of housings and vessels.

Construction applications:

• Switching frames: connection of metal structures for buildings and structures.

• Pipelines: welding of pipes for transporting gas and oil.

Special applications:

• Medical equipment: production of tools and devices with high accuracy.

• Microelectronics: welding of small components and boards.

Comparison of various welding methods

Comparison in accuracy, speed, costs and strength of the connections:

• Arc welding: high accuracy, average speed, affordable cost, strong compounds.

• Gas welding: average accuracy, low speed, affordable cost, average strength.

• Electro lane welding: high accuracy, high speed, high cost, very durable connections.

• Plasma welding: very high accuracy, average speed, high cost, strong compounds.

• Laser welding: the highest accuracy, high speed, high cost, strong compounds.

• Point welding: average accuracy, high speed, average cost, strong compounds.

Recommendations for choosing a method

• For thin sheets and simple tasks: point welding.

• For complex patterns and high accuracy: laser welding.

• For thick and large details: Electro -lane welding.

• For welding in conditions of limited space: gas welding.

Metal welding is an important process that requires the choice of a suitable method, depending on a specific task and type of material. Each method has its advantages and disadvantages that must be taken into account when choosing. In the future, further development of welding technologies is expected, which will improve the quality and effectiveness of compounds of various materials, as well as expand their use in various industries and construction.
