Tungsten Electrode -- Argon arc welding

 

1. The principle of argon arc welding

Argon arc welding is a gas-shielded arc welding method used argon as a protective gas , It is a welding method using arc heat between tungsten electrode and work piece for melting the base metal and filler wire, also known as GTAW (Gas Tungsten Arc Welding) or TIG welding (Tungsten Inert Gas).

2. The characteristics of argon arc welding

 

a. High quality of the weld. Since the argon is an inert gas that does not react chemically with the metal, while the argon does not dissolve in the liquid metal, as a gas protective layer so that the high temperature welding metal alloy elements will not Oxidation burn, and the protection effect is good. therefore, it can get a higher welding quality.

b. Welding deformation and stress is small, especially suitable for the welding of thin pieces.

c. A wide range of materials can be welded, almost all of the metal materials can be argon arc welded.

d. Operation technology easy to grasp, easy to achieve mechanization and automation.

 

3. TIG welding material

TIG welding materials are mainly tungsten electrode, argon and welding wire

4. The classification of argon arc welding

 

--According to the electrode materials can be divided into:

a. Tungsten argon arc welding (GTAW / TIG)

b. Metal Argon Arc Welding (MIG)

 

--According to the operating mode can be divided into:

a. Manual argon arc welding

b. Semi-automatic argon arc welding

c. Automatic argon arc welding

 

--According to the type of power can be divided into:

a. DC argon arc welding

b. AC argon arc welding

 

5. Equipment for argon arc welding

 

--The manual TIG welding equipment consists of welding source, welding torch, gas supply system, control system and cooling system.

(1) welding power supply

TIG welding requires the use of steep drop characteristics of the welding power supply, DC power supply and AC power. (Commonly used DC TIG welding machine WS-250 type, WS-400 type; AC TIG welding machine with WSJ-150 type, WSJ-500 type; AC-DC TIG welding machine WSE-150 type, WSE-400 type, etc. Sen Song company for the Panasonic TSP-300 type.

 

--Resistance welding

 

1. Application of resistance welding

 

Using the quality heating to melt the parent material by the large current and pressure is the basic principle of resistance welding, such as resistance spot welding, projection welding, seam welding, seam welding, etc.

 

2. Characteristics of resistance welding

- Efficient

- Easy to learn for beginners

- Less deformation

- No need for welding wire, reagents and consumables

- Low cost
