In the section on labor protection, labor protection measures were developed during welding and fire safety.

Introduction

The founders of welding are: V.V. Petrov (17311834), N.N. Benardos (18421905), N.G. Slavyanov (18541897).

In 1802, for the first time in the world, V.V. Petrov discovered and observed an arc discharge from a permanent and super-powerful volt pole. This pole or battery, as Petrov called it, was the most powerful source at that time. After 80 years, N.N. Benardos in 1881 first used the Electric Arc between the carbon electrode and metal for welding.

Almost simultaneously with Benardos, another Russian scientist N.G. Slavyanov worked. Slavanov developed a method of arc welding with a metal electrode and a protective welding zone with a flux layer and the world's first mechanism "Electric fuse - for semi-automatic supply of an electrode rod to the welding zone. The welding method was called: arc welding according to the method - Slavyanovy. The first demonstration took place in 1882. Currently, there are a large number of welding devices, for example: semi-automatic for arc welding in protective gases, in which wire is supplied automatically, and movement by a burner is carried out manually. In this case, the welding machine is automatically wired and moved by the torch. Gas welding - In this method, parts are welded with a flame, which is formed when gases or vapors of combustible liquids burn.

Laser, plasma, remote controlled, underwater welding.

Selection and justification of welding method

Consider welding the following structural elements:

Welding of a ring seam pipe Ø159x8+ bottom (No. 1)

Welding of a ring seam pipe Ø89x6+ flange (No. 1)

Welding of a branch pipe of Ø28x6 to the bottom (No. 5)

As a welding method for welding ring butt and corner seams, mechanized welding with a melting electrode in a carbon dioxide gas medium or mixtures of argon and carbon dioxide is used. The choice of welding method is justified both by the requirements of the drawing and by the technological capabilities of the welding process, such as productivity, quality, equal strength of the weld along the length, which is important for structures experiencing internal pressure. The advantages of this type of welding are also the productivity of the process and the ability to conduct the process in different spatial positions.

Capillary control

Colour or magnetic powder inspection shall be performed on welds not available for radiographic or ultrasonic inspection.

Color and magnetic powder inspection of welded joints should be carried out in accordance with GOST 1844280.

Conclusion

As a result of the diploma project, the technology of the process of assembling and welding the filter chamber - gas purification separator was developed.

For this purpose, the most rational method of welding is proposed, welding materials and welding equipment are selected, welding modes are calculated, devices for assembly and welding of the product are designed. The indicators of the economic evaluation of investments were calculated, from which it was concluded that the implementation of the proposed welding process will be profitable. Hazardous and harmful factors were also identified in the production of the designed product and measures were developed to combat them.

The use of new technology in production will help to increase labor productivity, reduce the cost of the product, improve working conditions of workers, and give an optimal economic effect.
