Welding technology and skills of argon arc welding?

Argon arc welding is a welding technology using argon as shielding gas. Also known as argon shielded welding. That is to say, argon shielding gas is introduced around arc welding to isolate the air from the welding area and prevent the welding area from being oxidized. Next, I will tell you in detail the methods of argon arc welding spot welding and the welding skills and techniques.

First, argon arc welding spot welding?

1. Before welding, prepare the argon cylinder, install the argon flowmeter on the cylinder, and then connect the gas pipe with the air inlet on the back panel of the welder, and ensure that the joint is tight to prevent air leakage.

2. Connect the argon arc welding gun, gas connector, cable quick connector and control connector to the corresponding sockets of the welding machine. The workpiece is connected with the "+"connecting bolt through welding grounding wire.

3. Connect the power cord of the welder and check whether the grounding is reliable.

4. After turning on the power supply, choose AC argon arc welding or DC argon arc welding according to the welding needs, and set the line switch and control switch to AC or DC. Note: These two switches must be used synchronously.

5. Set the welding mode switch to the "argon arc welding" position.

6. Open the argon bottle and flowmeter, and turn the gas test switch to the "gas test" position. At this point, the gas will flow out from the welding torch. After adjusting the gas flow, turn the gas testing and welding switch to the "welding" position.

7. The welding current can be adjusted by the current adjusting handwheel. The clockwise rotation current decreases and the counterclockwise rotation current increases. The adjustment range of current can be determined by the current size change-over switch.

8. Select the appropriate tungsten rod and the corresponding chuck, then grind the tungsten rod into a suitable taper and install it in the welding gun. After the above work is completed, press the switch on the welding gun for welding. /article/image/2022/0 1/26/6 1f 1 188 a02a 1 1-thumb . png
