Welding Work

​

Welding is one of the most common methods for joining various metal parts and structures, providing very high strength for the finished products. Generally, the physical and mechanical properties of a weld match or exceed those of the base materials.

​

Types of Welding:

​

·        Arc Welding: This method connects parts by using heat generated from an electric arc that forms between the base material and the welding electrode. Arc welding is most frequently used with standard carbon steels.

·        TIG Welding (Tungsten Inert Gas): This process also utilizes an electric arc but employs a shielding layer of inert gas to prevent air from contaminating the weld area and oxidizing the molten weld pool. TIG welding is suitable for joining stainless steel, heat-resistant alloys, aluminum, magnesium, and various other materials.

·        Resistance Welding: This technology involves two sequential processes: heating the metal until it becomes plastic, followed by mechanical deformation of the components. Resistance welding can be in the form of spot, seam, or projection welding.

·        Gas Welding: In this technique, the edges of the parts are melted, and filler material is added to the molten pool. It’s commonly used for fabricating thin-walled sheet and tubular steel structures. The metal is melted through the combustion of acetylene in pure oxygen. The main advantage of gas welding is its portability and independence from external power sources.

·        Plasma Welding: This method is used for welding high-melting-point metals like molybdenum, tungsten, nickel alloys, and special steels. The welding process is conducted using a plasma jet that can reach temperatures up to 30,000°F.

·        Laser Welding: Laser welding is one of the most efficient methods for joining metal parts. It offers high productivity, consistent weld formation, limited thermal impact on the workpieces, and the capability to weld large structures.

​

These are just a few of the most commonly used types of welding. There are also other, less popular welding methods that are typically used for specific applications. For example, in some industries, thermomechanical joining of dissimilar metals is achieved through friction, and explosion welding is effective for producing bimetals.

​

Applications of Welding Welding is utilized for a wide range of technological and structural tasks. Here are several common applications of this metal processing method:

​

·        Manufacturing Metal Structures: Welding can create solid metal constructions of nearly any complexity and size, such as ramps, fences, load-bearing elements of buildings, vehicle bodies, sports equipment, hangars, and various frames and frameworks.

·        Production of Gates: Welding can produce both strong and aesthetically pleasing structures. This technology allows for the fabrication of sliding and hinged gates made from profiled sheet metal, which is a popular material for enclosing residential lots and industrial facilities. Welding can be performed not only in a factory setting but also directly on-site.

·        Manufacturing Stairs: Escape routes for fires or other emergencies must meet very strict standards. Only welded fire escapes can ensure the necessary strength and reliability. These structures are installed inside or outside residential high-rise buildings, commercial centers, and industrial facilities.

A wide variety of equipment is used for welding, ranging from simple, compact household transformers to powerful industrial automated systems.
