Incompletely interpreted and defective parts
Incomplete penetration refers to defects caused by the fact that the base metal does not melt and the weld metal does not enter the joint. According to the welding method of the welded parts, the roots are not welded and the middle is not welded.induction welder.
The root is not welded because the liquid weld metal does not enter the blunt edge of the root, and most of it exists in the single-sided welding of the V-shaped or U-shaped groove. The middle is not welded because the liquid metal does not enter the middle blunt edge, and most of it exists in the double V-shaped or double U-shaped groove double-sided welding. The weld is not welded to the defect The lack of penetration in the weld will reduce its effective area and seriously reduce the mechanical properties such as the strength of the welded parts. Incomplete penetration will also cause stress concentration and severely reduce the fatigue strength of the weld. In addition, when the welded part is under load-bearing stress, it may develop into a crack if it is not welded, and may eventually cause the weld to crack. The incomplete penetration is more harmful than the defects such as pores, slag inclusions and tungsten traps, which are harmful defects.
Welding plugging - preparation before welding
In industrial production, some continuously operating equipment leaks for a variety of reasons. induction heater. Such as pipes, valves, containers, etc. The occurrence of these leaks affects the stability of normal production and the quality of the product, and pollutes the production environment, causing unnecessary waste. What's more, some media, such as toxic gases, grease, etc., will cause serious damage to safe production and the surrounding environment. The sealing of equipment with pressure, oil or toxic substances is a special welding under abnormal working conditions. Unlike normal welding specifications, it emphasizes safety during operation. Precautionary safety construction measures must be in place before welding to ensure the safety of the workplace, welders and other workers. Welders must be experienced and skilled, and must have technically experienced welding engineers to provide safe technical guidance. For example, a certain type of fuel tank must understand the capacity, ignition point, pressure, etc. of the oil inside, and can ensure that the welding process will not cause personal injury or even a greater safety accident, in order to be able to construct. Therefore, the following points must be done before welding and welding: First, safety relief. Before welding is plugged, it must be determined whether the pressure of the equipment to be welded will constitute personal injury. Or under the influence of the welding heat source, the equipment has a safe pressure relief passage (such as a safety valve installed). Second, temperature control, before the welding is plugged, all measures must be taken to prevent fire and explosion. In welding, the welder must strictly follow the minimum and minimum heat input specified in the process documentation, and must perform safety cooling measures during welding to prevent fire or explosion. Third, anti-poisoning, when the container or pipeline containing toxic substances is plugged and welded, it is necessary to timely discharge the toxic gas leaking and timely supply of fresh air. At the same time, it is necessary to do a good job of pollution isolation of toxic substances.

Causes damage to the tip of the pin stud welder
Because of the good and reliable welding quality of the stud welder, as long as you can use the right stud material in the right way, you can ensure that the two materials can be firmly connected together. An important device in the stud welder is the pinch tip, which can cause damage to the pinch head if not handled properly. Let's ask the industry's leading stud welder manufacturers to introduce the reasons for the damage caused by the clip.induction welder.
1, the stud is too deep
Whether it is an energy storage type stud welder or an arc type stud welder, the studs are directly "planted" on the base metal. Therefore, if the studs are installed too far too close to the current, then it will be because The temperature of the contact is too high, causing the tip of the clamp to burn out. Therefore, in order to avoid the occurrence of damage to the clamp head, the stud should be kept at a certain distance.
2, the chuck is too loose
If there is slack in the collet of the stud welder, the stud and the stud are too loose. If you continue to use a stud welder to weld various materials in this state, then The tip of the clip will be damaged due to poor contact. In order to avoid damage to the tip of the gun for this reason, the chuck should be kept properly tight, and it should be adjusted in time if the chuck is found to be slack.
3， There is rust on the stud
When using a stud welder to weld materials, all related objects should be kept smooth and clean. If the surface of the material being welded is not clean, the welding effect will be unsatisfactory, and if the studs are used, Rust, then it will lead to poor contact during welding, it is possible to burn the tip of the clip.
What is the maintenance of the nut projection welder?
The current users have already understood the reasons for the cleaning work before and after the daily operation of the nut projection welder, which may also be a trap for future failure. Because the nut projection welding machine is a welding equipment evolved from the spot welding machine, it is mainly used to realize the welding of small parts. Because the price of the nut projection welding machine has the advantages of small welding core and high precision of welding point control, Widely used in small parts processing enterprises. The following is a detailed introduction to the maintenance of the nut projection welder?
1. Do grounding to prevent accidental leakage
The nut projection welder cannot touch the next two electrodes during use and cannot be used to disassemble the machine or modify the structure of the machine. Regularly grind the electrode tip with a file or sandpaper, or replace it with a new one. When setting the welding pressure and the forging pressure, the characteristics of the nut projection welding machine should be considered. The pressing speed of the projection welding is very important. If the breaking is too fast, the generated heat will be insufficient and a qualified fuse will not be produced, so that the welding pressure will be in the initial stage. The workpiece is completely compacted, but not comminuted and tracked at the same time, not only to ensure the generation of heat, but also to form a completely molten core under pressure.induction welder.
2. pay attention to the regular application of lubricant
The cylinder of the nut projection welding machine, the solenoid valve, the welding head guide rod spray lubricating oil, the oil mist maintains enough lubricant, the oil mist enters the solenoid valve or the cylinder to ensure smooth running and prolong the service life. The screws should be tightened before use. In particular, the screws between the soft copper and the electrodes are fixed and stable. After use, the water should be kept clean in time. The oxide between the electrode rod and the electrode arm is periodically cleaned to maintain good contact.
3. Regularly check the equipment for abnormalities.
The weekly nut welder inspection work is indispensable. When using the cooling fan to rotate smoothly, the starting device has abnormal sound or smell, and each terminal is loose. Nut projection welders should not be used in closed and corrosive spaces and should be operated in a ventilated, dry room. Turn off the switch or power distribution switch. (The red light on the control box should be visible and extinguished). Press the white button under the water filter to drain the water stored in it.
In summary, it should be noted that the water temperature in the cooling water pipe of the nut projection welding machine should be reasonable, and the residual water in the cooling water pipe will be blown away by compressed air to avoid freezing the pipe when the winter ambient temperature is below zero. Turn off the air supply, unplug the air hose, if there is too much oil in the oil mist of the nut welder, if it is less than a small scale, it should be that the oil mist needs to add lubricant. (It is necessary to use a lubricant suitable for the cylinder and install the oil mist according to the customer's needs).
Introduction of UHF induction heating equipment
Ultra-high frequency induction heater equipment is mostly used for surface quenching of industrial metal parts . It is a metal heat treatment equipment that generates a certain induced current on the surface of the workpiece , rapidly heats the surface of the part and then rapidly quenches the surface . The working principle of the ultra-high frequency induction heating device is as follows : the workpiece is placed in the inductor , and the inductor is generally a hollow copper tube that inputs an intermediate frequency or a high frequency alternating current (1000-300000 Hz or higher ) . The alternating magnetic field generates an induced current of the same frequency in the workpiece . The induced current is uneven in the distribution of the workpiece , strong on the surface , and weak inside , to the core close to 0 , using this skin effect The surface of the workpiece can be heated rapidly , and the surface temperature rises to 800-1000oC in a few seconds , while the core temperature rises little .
