What is welding machine? Classification of welding machines

In the process of manufacturing industry, mechanical processing, we can not lack a specialized tool is welding machine. So what is the function of welding equipment and how is the role of welding machine in life and production and construction important? Let's TipsMake.com learn the basic concepts of welding machines, how to classify and distinguish popular welding machines in the current mechanical application offline!

What is welding machine?

Basics of welding machine

Imagine separate pieces of metal how to connect to each other? Welding work will help you in this case very simple! By melting welding, the welding machine will help to make connections between heterogeneous (or any thickness) metals or alloys that are stable and extremely durable.

Basic principle of welding machine

Basically, there are two ways to weld: welding by melting at the metal to be welded or melted while adding welding materials.

When welding metal melting, in the weld position, the metal will reach liquid state. Local melting of the metal is performed at the edges of the coupling element. When the metal heating source is turned off, the molten solder will condense to form a solid monolithic weld with a two-part link structure.

Clearly with such welding mechanism, the application in the manufacturing industry, mechanical engineering is a preliminary step necessary for a production machine frame or to recover the structures and details to be dismantled.

Classification of welding machines

There are many ways to classify different welding machines. For example, based on manufacturing technology, people are divided into two types of mechanical welding machines and electronic welding machines; Small power inverter welding machines of about 200A or less are also known as mini electronic welding machines because they are small, compact and lightweight as its name suggests. In fact, the most commonly used way of classifying welding machines is based on welding techniques, often divided into categories: rod welders, TIG welding machines, MIG welding machines, MAG welders, multipurpose welding machines. (combine 2 - 3 different welding techniques). In addition, to complement the welding of metals and alloys, mechanics often use an additional device for plasma metal cutting machines. Here are detailed information about each type of welding machine, cut this.

What is rod welding machine?

Rod welding machine, also known as manual arc welding machine, is based on manual arc welding principle. This is a hot melt welding process that uses electrodes in the form of welding rods usually with a shield and no protective gas, in which all welding operations are done by the welder.

Application : Electric arc welding machine specialized for connecting metal parts such as iron, steel, stainless steel . together through melting and adhesion of metal materials and welding materials.

For example, the Hong Ky SR-200R rod welding machine has a high operating capacity of up to 8.3 KVA, allowing for quick and efficient welding, suitable for soldering, for extremely beautiful welds.

What is TIG welding machine?

TIG welding machine is a type of welding machine that applies welding technology with tungsten electrode in an inert atmosphere. The gas will protect the weld from outside air penetration.

Application : TIG welding machine can be used for many metals such as stainless steel, aluminum, magnesium, copper and copper, nickel and nickel alloy, low carbon steel with different thickness .

For example, the Hong TIG HK TIG 200E electronic welding machine can weld chopsticks and weld Argon gas, using 1-phase 220V power and maximally save electricity thanks to the application of Inverter technology. Size of 1.6mm welding rods - 3.2mm and 1.6mm - 2.4mm welding needles, the ability to adjust the output current 10A - 200A and the average working efficiency reaches 60%, bringing high efficiency and productivity. working.

What is MIG welding machine?

MIG welding machine adopts metal arc welding method in environment with protective gas. The main electrode here is the melted solder wire, which is automatically applied to the welding object, the environment is Argon or Helium inert gas.

Application : MIG welding machine is often used to weld alloys, non-ferrous metals and high alloy steel Al, Ni, Cu .

For example, MIG SMARTER INMIG-250 welding machine is commonly used in the production of tables, chairs, bicycle frames, motorcycles, mechanics, etc., because of its ability to weld most metals, easy to automate and for long welds without interruption.

What is MAG welding machine?

MAG welding machine, also known as semi-automatic welding by molten electrode in a protective atmosphere of CO ₂ gas. When welding CO2 will be heated and produce insoluble CO in liquid metal (structural steel), especially when at high temperature it will expand and move at high speed so it has a protective effect efficient melting welding area.

Application : MAG welding machine is used to weld structural steel with low and medium carbon content. In addition, the structure with large thickness can also use mixed gas (Oxygen, Ar .)

What is Plasma cutting machine?

Plasma cutting machine uses the principle of Plasma operation to perform metal cutting process. The principle of Plasma cutting is based on the utilization of very high temperatures and the high speed of movement of gas from the nozzle of the Plasma cutting head to melt and blow metal from the cutting groove. During use, the cutting edge is flat and not grainy, to create a perpendicular cutting edge that needs to reduce the cutting speed.

Application : This plasma cutting machine is commonly used in large-scale industry.

For example, the HK 70 Hong Ky Plasma Cutting Machine can cut on copper, stainless steel, iron materials . including non-ferrous metals and high hardness materials. The machine operates stably, maximizes power saving, with high working efficiency, safety with over-temperature, overload, and unstable power supply modes.
