What is the difference between argon arc welding machine, pulse argon arc welding machine, pulse AC

AC TIG Welding Characteristics Independent Amplitude Current control can be adjusted to set the positive and negative half-wave current values of AC independently, so as to accurately control the heat input of the workpiece and electrode. Balance ratio control, which allows for the adjustment of the oxide removal function, is the basis for high-quality welding of aluminum. These models expand the range of applications.

Frequency adjustment can control the width of the arc cone, which can improve the control of arc direction. AC waveform advanced square wave melt pool fast solidification, deep penetration and fast welding speed. The gentle arc of the soft square wave allows for maximum control of the melt pool and good wetting.

Sine wave is suitable for users who prefer traditional arcing, quiet welding and good wetting effect. The triangle wave reduces the heat input, which is especially suitable for the welding of thin aluminum plates, and the welding speed is relatively fast. The DC TIG welding characteristics are very smooth and accurate....

Pulse argon arc welding machine is an argon arc welding machine that uses pulse current to achieve welding, which can effectively control the welding heat input, has deep penetration, high weld strength, and can achieve single-sided welding and double-sided forming. The better pulse argon arc in the domestic welding machine is Nebula's nebula

A series of digital welding machines, high current control accuracy, good product consistency, and concentrated arc.

TIG welding is a general term, pulse TIG welding, pulsed AC and DC TIG welding are all classifications inside.

The pulsed AC/DC argon arc welding machine contains the functions of the pulsed argon arc welding machine, and also adds the function of AC argon arc welding.

The welding of aluminum must be AC argon arc welding function.

First, the reference is different.

1. AC argon arc welding: argon arc welding that uses the welding power supply to output an uneven current to the arc with a certain regular change.

2. DC argon arc welding: an arc welding machine that adopts tungsten electrode and non-melting electrode, argon gas protects the welding pool, and the welding process current is always unchanged.

Second, the principle is different.

1. AC argon arc welding: the use of continuous, uninterrupted fundamental current (also known as dimension arc electric combustion Hui lap current) to maintain the ionization channel of the main arc, and periodically apply a copolar high peak pulse current to generate a pulse arc, to melt the metal, control the transition of the molten droplets, to achieve the purpose of welding.

2. DC argon arc welding: the welding wire is fed through the wire wheel, and the contact tip conducts electricity, generating an arc between the base metal and the welding wire, melting the welding wire and the base metal, and using inert gas argon to protect the arc and molten metal for welding.

Third, the characteristics are different.

1. AC argon arc welding: it can accurately control the heat input and melt pool size of the workpiece, improve the protection ability of the weld against burn-through and the molten pool, and easily obtain a uniform penetration depth, especially suitable for thin plate (thin to full-position welding and single-sided welding double-sided forming.

2. DC argon arc welding: high current density, heat concentration, high deposition rate and fast welding speed. In addition, it is easy to start arcing. It is necessary to strengthen protection because the arc light is strong and the smoke is large, so it is necessary to strengthen the protection.

I hope my judgment can help you, and if mine is helpful to you, please give me a thumbs up! Thank you, and I wish you a happy life!

First, the welding current is different.

The current in the DC TIG welding process is always constant.

However, in the process of pulsed argon arc welding, the welding current has two currents, the base value and the peak value, alternately change.

Second, the heating and cooling rates are different.

Pulse argon arc welding each solder joint is heated and cooled rapidly, the molten pool metal condenses quickly during the welding process, and the high temperature residence time is short, which can reduce the tendency of cracks during the welding of heat-sensitive materials.

Whereas, DC TIG welding heats and cools slowly.

Third, the scope of the heat-affected zone is different.

Compared with DC TIG welding, the pulsed arc can obtain a larger penetration depth with a lower heat input, so the heat-affected zone can be reduced under the same conditions. When welding heat-sensitive materials, reducing the pulse current passage time and base current value can reduce the range of the heat-affected zone to a minimum.
