I just learned argon arc welding, why is it either that it can t be welded or that it is welded thro

In our country, welding operations need to be licensed, welders are the type of work that belongs to the access category, in the professional qualifications of skilled personnel, only five of the 81 types of work in the access category, welders are one of them, and the actual situation is that most of the industry practitioners are unlicensed operations. With the continuous standardization of technology and the relevant requirements of the industry, more and more people want to take a welding certificate, the advantage of the certificate is still very large, first of all, the salary of the certificate and the non-certificate are very different, often able to reach more than double or higher level. Therefore, the issue of short-term welder training has naturally become a concern for practitioners.

Welding as an industrial "tailor" is a very important means of processing in industrial production, the quality of welding plays a decisive role in the quality of the product, so, what is the future development of welding technology?

Industry outlook. With the development of production, welding is widely used in aerospace, aviation, nuclear industry, shipbuilding, construction and machinery manufacturing and other industrial sectors, in China's economic development, welding technology is an indispensable means of processing. After entering the 21st century, welding is an important part of the manufacturing industry, and the rapid development, so it has brought unprecedented development opportunities to the welding industry.

At present, China consumes 300 million tons of steel every year (about tons of welded structure), and needs about 750,000 welding machines, and the welding industry will continue to grow in the next 8 10 years.

The current is too big or too small! The angle is not well controlled! The closer the tungsten needle, the better!

The technique is not skilled, and I do not pay attention to the melting changes of the molten pool

The current is not adjusted well, and there is no weld penetration.

The problem of welding techniques, I practice practice.

Reduce the current appropriately. Detect argon purity, at least yes. The reverse side should also be protected by argon. Speed up the welding speed, the welding is oxidized when the bottom is not laid, the bottom is not good, and the cover is definitely not beautiful.

TIG welding. It is a welding technique that uses argon as a shielding gas. It is also known as argon gas shielded welding.

It's arc welding.

argon shielding gas is used around the area to isolate the air from the welding area and prevent oxidation in the welding area.

Argon arc welding technology is based on the principle of ordinary arc welding, the use of argon to protect the metal welding consumables, through high current to make the welding consumables melt into a liquid state on the welded substrate to form a molten pool, so that the welded metal and the welding consumables to achieve metallurgical combination of a welding technology, because of the continuous delivery of argon in the high temperature melt welding, so that the welding consumables can not contact with the oxygen in the air, thereby preventing the oxidation of the welding consumables, so that stainless steel, iron hardware metals can be welded.

A type of tungsten inert gas shielded welding (TIG). It is a welding method that uses arc heat to melt the base metal and filler wire to form a joint under the protection of argon. It mainly controls three parameters: welding current, welding speed and argon flow.

Compared with manual welding, the arc and weld pool are visible and easy to operate; Sheet metal structures that can be welded to active metals; Weld seam***, the joint strength can reach 80% 90% of the base metal.

In 1930, inert gas shielded welding was invented in the United States, and in 1957, China began to use tungsten argon arc welding. It can be welded with stainless steel and high-temperature alloys.

Titanium alloy, aluminum alloy and other materials, used in nuclear energy, aerospace.

Shipbuilding, electronics, metallurgy and other industries.

Under the protection of argon, there is no oxidation of the surface. Hope.

Manual arc welding.

1. Causes.

1) Improper selection of welding rods.

2) The current is too low.

3) The welding speed is too fast, the temperature rise is not enough, and the speed is too slow, and the arc impulse is blocked by the welding slag, so it cannot give the base metal to the mountain tung.

4) The design and combination of welds are incorrect.

2. Prevention methods.

1) Choose a more penetrating electrode.

2) Use an appropriate current.

3) Use the appropriate welding speed instead.

4) Increase the degree of slotting, increase the gap between the teases, and reduce the root depth.

Summary. Hello dear, it's a pleasure to serve you! The argon arc welding machine cannot be welded without argon.

1. Argon arc welding is to use the inert gas argon as the shielding gas, if there is no argon protection, the outside air will interfere with the welding metallographic structure forming, such as oxygen, nitrogen, water vapor, etc., which will cause a large number of defects in the weld. Under the action of argon, these interfering factors are avoided, so that the weld is not easy to produce defects. 2. Argon arc welding is to use the inert gas argon as the shielding gas, if there is no argon protection, the outside air will interfere with the formation of the welding metallographic structure, such as oxygen, nitrogen, water vapor, etc., which will cause a large number of defects in the weld.

Under the action of argon, these interfering factors are avoided, so that the weld is not easy to produce defects.

Can an argon arc welding machine weld be welded without argon?

Can you weld stainless steel without gas for TIG welding?

Hello dear, it's a pleasure to serve you! The argon arc welding machine cannot be welded without argon. TIG welding is not gasless and stainless steel cannot be welded.

1. Argon arc welding technology is based on the principle of ordinary arc welding, using argon gas to protect metal welding consumables, 2. Through high current, the welding consumables are melted into a liquid state on the welded substrate to form a solution pool, so that the welded metal and welding consumables can achieve metallurgical combination, also known as argon gas shielded welding. Argon gas acts as a protective agent for welding consumables.

Not added. Welding wire.

If you turn the current down a little and solder slowly, there will be no problem you said. Weld-through means that your current is large, and your welding speed does not keep up, so you weld through.

Hello! According to your problem description, there are many reasons why the argon arc welding machine does not arc, and the common faults and detection and maintenance methods are as follows: high-frequency arc non-arcing.

Fault phenomenon: when argon arc welding, there is no high-frequency discharge, and the arc can be scratched. It means that there is no load voltage, and the argon arc welding gun is no problem, but it may be a problem with PCB1 and PCB6 boards.

There is no high-frequency discharge, it may be that the capacitor on the PCB6 is damaged, and it can be normal if the PCB6 board is replaced. No arcing. Fault Symptom:

When argon arc welding, there is a high-frequency discharge, there is no argon output and no arc, and there is a no-load voltage. There is high frequency, no-load voltage, which proves that the argon arc welding gun is no problem, there is no argon protection, argon arc welding will definitely not arc, at this time it is possible that the gas valve is damaged or the PCB1 board does not supply power to the gas valve. How to deal with it:

Use a multimeter to detect the wiring strip (XSI), 1, 2 pins and 6 pins on PCB1 CNI06, and the gun AC36V, indicating that the solenoid valve is damaged, replace the solenoid valve to solve, if the gun has no voltage, the PCB1 board needs to be replaced. The argon arc does not arc. Fault Symptom:

Manual welding is normal, and when argon arc welding, there is no no-load voltage output. Manual welding is normal, indicating that the main circuit is normal. The argon arc has the following possibilities for no-load voltage output:

The welding torch does not work. Use a multimeter to measure the 1 or 2 pins of the welding torch plug, if the torch is not passed, repair the welding torch switch or replace the welding torch can be normal. If the PCB5 relay does not work, replace the PCB5 board.

If the PCB5 is detected to be normal, it may be that the PCB1 board control circuit is faulty, and the PCB1 board needs to be replaced to be used normally.

Summary. Hello dear, <>

Why is the stainless iron welding not firm with argon arc welding, and the iron welding iron can't be welded? This is really the first time I've heard of argon arc welding iron, and in general, argon arc welding iron is very good. TIG welding is mainly used to weld iron and stainless steel.

If you can't weld the iron, then it must be that the current you are welding is too small. The accuracy of TIG welding is relatively high, and it can be welded with a small current. At this time, you need to increase the current a little bit to be able to weld.

Why is stainless iron welding not firm with argon arc welding.

Hello search good dear, <>

Why is argon arc welding welded stainless iron welding not firm, argon arc welding welding iron welding is not erected socks? This is really the first time I've heard of argon arc welding iron, and in general, argon arc welding iron is very good. TIG welding is mainly used to weld iron and stainless steel.

If you can't weld the iron, then it must be that the current you are welding is too small. The residual accuracy of TIG welding is relatively high, and it can be welded with a small current. At this time, you need to increase the current a little bit to be able to weld.

The reason why argon arc welding does not destroy the balance chain may be that the current is too small and the iron cannot be melted. Or the angle of the welding torch is not suitable, or it may be that the wrong welding consumables are used to cause the welding to not be blocked.

If the operation reason is excluded from the welding, 1, argon purity 2, the machine parameters are not adjusted correctly, such as the size of the welding current, the size of the arc and the hand arc current 3, the size of the groove design and the welding is not transparent, it will also affect the welding quality of the molding is not good 4, the gas information protection is not in place, and some need to do double-sided protection, such as the pipeline docking that needs to be detected by the world, the need to slip the gas protection on the back, or the protective agent of the back protector We-60F.
