What is the matter with the intermittent welding process of the second welding process?

There are many reasons for frying wire, the main reasons are 1, the wire feeding speed and voltage do not match, and the voltage should be slightly increased. 2. There is a problem with the workpiece, for example, there is a degree of zinc on the surface. 3. The wire feeding hole of the contact tip is seriously worn out due to long-term use, and the wire feeding hole is too large, the recommended method is to knock it with a hammer, so that the welding wire does not shake in it, and the wire feeding is smooth.

4. There is iron slag in the conductive nozzle, which is easy to stick to the welding wire, but the wire feeding is unstable because the welding wire machine is pushing in the back, so it is best to replace it with a new one. 5. There is a problem with the melt wire setting and welding consumables of the welding machine, which is not common. If there is a problem with the melting wire, you need to find a machine to repair it, and if there is a problem with the welding wire, you need to replace it!

That's all for that.

Most of the time the quality of the welding wire is not good, or the impurities of the weldment are too large

The principle of the second welding is that the welding wire and the weldment are used as two electrodes to generate an electric arc, and the heat of the arc is used to melt the metal, and carbon dioxide gas is used as the shielding gas to protect the arc and the molten pool, so as to obtain a good welding joint.

1. The full name of the second protection welding is: carbon dioxide gas shielded welding, which is a welding method.

2. This welding method has become one of the most important welding methods for ferrous metal materials.

3. Features: 1) Low welding cost. Its cost is only 40 50% of submerged arc welding and electrode arc welding.

2) High production efficiency. Its productivity is 1 4 times that of electrode arc welding.

3) Easy to operate. Open arc, no limit to the thickness of the workpiece, can be welded in all positions and can be welded downward.

4) High crack resistance of welds. The weld is low in hydrogen and also has less nitrogen.

5) The deformation after welding is small. The angular deformation is 5 thousandths, and the unevenness is only three thousandths.

6) Small welding spatter. Welding spatter can be reduced when ultra-low carbon alloy or flux-cored wires are used, or AR is added to CO2.

If the quality of the gas is not good, there will also be the phenomenon of fried wire, and it will not be adjusted well.

It should be your current, and the voltage is not batched.

The quality of welding, the weld that should be welded at one time is often divided into several sections to be welded. The following lessons are for reference only: Nine Reasons Why:

1.The welding wire has a hard bend2The welding wire is corroded3

The thickness of the welding wire is uneven 4Improper use of wire feeder compression wheel 5The welding torch is bent too much when it is used by 6

The welding torch wire feeding hose grinds out the groove 7The contact tip is not cleaned in time; 8.The wire feeding hole of the contact tip is too worn9

The current and voltage do not match during welding.

1515 bar, the general carbon dioxide gas shielded welding wire is a low-carbon count steel, so the melting point is about the same as that of Qinbeishou low-carbon steel.

When burning the second protection weld, why does the welding wire suddenly fuse as soon as it touches the weld, and what is the reason?

The pressure of the pressing wheel is too high. The resulting wire is flattened and broken at the wire feeder. It is sufficient to reduce the pressure of the wire feeder so that the wire can be fed smoothly.

The higher the wire feeding pressure, the better. 2: The problem of the measurement of the welded wire beam.

The diameter of the inferior miscellaneous small factory welding wire is uneven, and the diameter of the higher than the oak is stuck at the wire feeder, resulting in broken wire. 3: The welding wire does not match the wire feeding hose.

For example, if you use aluminum alloy welding wire or other soft welding wire, you must replace the Teflon wire feeding hose. Ordinary steel wire hoses are only used for welding with low-alloy structural steel welding wires. Using a steel wire feeding hose to weld a softer material welding wire will also cause the wire to get stuck in the wire feeding hose, and the wire feeder will break at the wire feeder due to the continuous wire feeding.

If you send it, forget it. Problems with the welding wire are a little more likely. Welding wire branch shouting?

Diameter? How long is it stored? Is there rust?

Clean up all the paths that the wire has passed. The force of the thread pressing wheel is too great, and it is not good. That's my answer!

Hope it works for you! Thank you!

Dear, hello, for your question [what happens to the second welding machine automatically out of a section of wire after welding] This question is the following answer for your reputation: kiss the second protection welding inspection Zen section of the welding wire when a long line comes out This is because: First, check the lower stool air valve to see if the air supply is not smooth.

The air volume does not affect the wire feeding speed, and the wire is also supplied when the air valve is closed, and the speed remains unchanged. Second, check whether the quality of the welding wire is not up to par, thick and fine. This situation is almost zero, and welding consumables manufacturers have made control and self-inspection.

Third, straighten out the line and see if the path of wire feeding is bent. Highly likely, but as a welder should have found out. Fourth, check the switch on the welding torch to see if there is any damage.

It doesn't exist, and if it's broken, it doesn't move. Fifth, find a professional to repair it. Reasonable.

The long length of the wire when the carbon dioxide gas shielded welding nozzle is closed is because the arc closing current switch is turned on. So when the welding is finished, you release the torch switch, but the current does not stop immediately, and it will continue to spit out a small piece of wire. In this case, you can turn off the arc current switch on the welding machine, and then when you release the torch switch during welding, the welding wire will stop immediately.

There are two reasons for this:1Release the switch when extinguishing the arc, do not move the welding gun, wait for a while and then move the welding gun.

2.The (2t, 4t or manual automatic or none, repeated) toggle switch on the welding machine panel.

1. There are two adjustable rotary buttons on the second protection welding machine, one is the current and the other is the voltage, and the current is to adjust the speed of the second protection welding wire.

2. The first time the switch is pressed, it belongs to the wire feeder current, and the second time the switch is pressed, there are two kinds of situations: it will be loosened when pressed, and the welding machine will stop working at this time; If you hold it down, then the welding machine current, which is what we call the arc closing current. The mediation of the arc closing current is torsion on the welding machine.

If it is an inverter welding machine, there will be an additional adjustment torsion called inductor, which is used to control the penetration depth. The wire feeding written on the welding machine is manual and automatic, which corresponds to the arc closing without arc retraction. The general two-protection welding machine is nothing more than the power switch arc retraction, no arc retraction, wire inspection, gas detection, wire diameter, arc retraction current, arc retraction voltage, inductance and other buttons.

3. The second protection welding machine is the abbreviation, and the full name is carbon dioxide protection welding machine. The hidden resistance welding machine is composed of transformers, control circuit boards, switches, frames, etc., as well as auxiliary equipment such as carbon dioxide cylinders, wire racks, wire feeders, etc. Due to the large welding current, generally hundreds of amperes, the wire is very thick, mostly copper coils, but also aluminum coils.

Summary. Hello, if this situation generally occurs, there are two reasons:1Failure of welding power supply (welding machine);

2.Although the wire feeding speed has been adjusted to the maximum, in fact, due to the failure of the wire feeder or other reasons, the wire feeding speed has not been unable to go up, and the smaller the wire feeding speed, the smaller the penetration depth in the case of fixed welding voltage.

Summary. Extended Information: Welding, also known as welding, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by means of heat, high temperature, or high pressure.

There are many types of energy** in modern welding, including gas flames, arcs, lasers, electron beams, friction and ultrasonics. In addition to being used in factories, welding can also be performed in a variety of environments, such as in the field, underwater, and in space. Welding can be dangerous to the operator wherever it is, so proper precautions must be taken when performing welding.

The possible injuries to the human body caused by welding include burns, electric shock, vision damage, inhalation of toxic gases, excessive ultraviolet radiation, etc.

What is the reason for the welding of the second guarantee welding wire.

Hello, I have seen your question and am sorting out the answer, please wait a while

The switch that started the welding machine was broken or the cable was broken. The switch on the welding gun has two contact signals, when the welding switch is pressed, one is sent to the wire feeder for wire feeding, and the other is sent to the welding machine for arc welding. Now the signal sent by the token to the welding machine has not been delivered, this is a common problem, it is easy to damage the signal cable by dragging the welding torch around, so it will be good for the electrician to check and connect.
