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 battery spot welding machine is mainly an industrial equipment that uses micro-computer control technology for welding operations. induction welder. It not only has three welding modes such as single pulse, double pulse and multi-pulse, but also can be used to directly adjust the welding requirements of different workpieces. The parameters thus ensure the accuracy and repeatability of the welding operation and are often used in a variety of workpiece welding operations. So, what are the operating points that people should pay attention to when using a professional battery spot welder?

1. When using a battery spot welder, care should be taken to place the nickel sheet on the surface of the lithium battery, and use a suitable type of battery clamp to move the nickel sheet on the surface of the lithium battery. Finally, use the foot to step on the pedal of the welder. Welding can be done.

Second, people need to press the nickel plate and the battery with two needles when using the battery spot welding machine, and also pay attention to the welding needles touching each other to avoid affecting the welding effect when welding the workpiece.

Third, when using the battery spot welder, the welding pressure of the welding machine should be adjusted, that is, the knob that uses the hand to screw the welding pressure, if the rotation is in the clockwise direction, the pressure is increased, such as rotating in the counterclockwise direction. In order to reduce, people can adjust the appropriate pressure according to the welding requirements before performing the welding work.

Fourth, in order to prevent accidents and other accidents, people should do sufficient inspection work before using the battery spot welding machine for welding work. For example, when checking the carbon deposit of the welding pin, it should be cleaned with a file or sandpaper, and the right foot is also applied. Under the foot pedal of the welder, the head of the welder should also be lowered to visually check whether the needle is accurately aligned in the position to be welded.

Battery spot welders are widely used in high efficiency laser spot welding or sealing welding in the battery industry, mobile phones and other related industries. induction welder.  For manufacturing companies, choosing a high-quality battery spot welder determines the rate of product qualification, and can improve employee productivity, save time costs and produce good quality products. A good quality battery spot welder has the following four characteristics:

First, the welding effect is excellent

The battery spot welding machine has the advantages of high strength, small welding point, no pollution, easy control, low processing cost, and can be processed into various micro-miniature metal devices in addition to widely used in mechanical and electronic fields. The spot welder is especially suitable for the sealing welding of stainless steel shells and aluminum shells in the manufacture of lithium batteries, and has high customer acceptance.

Second, the operation is simple and convenient

The battery spot welding machine adopts pneumatic control, the micro switch controls the welding ignition, the welding point is white and bright, it is very firm, can maintain consistency, and is equipped with a positioning fixture. There is no technical requirement for the operator, and the batch welding can be quickly standardized. Products with high qualification rate have high production efficiency.

Third, the performance is stable and reliable

It is controlled by 16-bit microprocessor and has a variety of welding program storage. The battery spot welding machine can maintain the same energy output per weld. It has high stable output and is not affected by the fluctuation of the power grid. It can be applied freely on the production line.

Fourth, powerful

The battery spot welding machine has the functions of automatic compensation of power supply voltage fluctuation and strong anti-interference ability, stable operation and good solder joint consistency. The main circuit adopts high-power thyristor non-contact control, high reliability and long life. The battery spot welding machine adopts a high performance pneumatic system, the upper electrode movement speed is adjustable, the welding speed is fast, and the impact and noise are small.

Energy storage stud welding does not require gas protection and is relatively simple to operate . It is suitable for automated production lines , so this welding technology has been widely used in automotive welding production lines . The productivity of stud welding depends on the charging speed of the capacitor , which can be achieved by hand welding up to 8/min and automatic welding to 60/min . induction welder.

The sensor is a kind of precision tool, which has high price and high technical content. Therefore, it must be carefully used and carefully maintained.

1) When multiple sensors are used at one point of use, there is a sensor storage rack and numbered.

2) Before using the sensor, wipe the contact surface with a fine gauze. Handle it gently to prevent bumping and deformation.

3) When installing the sensor, the clamping mechanism such as the pressing bolt or the eccentric chuck must be tightened, and the positioning block fixing screws should be checked frequently and should not be loosened.

4) Water connection is the key, no mistakes are made, no omissions are made, and power is allowed to be confirmed after water is passed.

5) The effective circle and workpiece clearance should be checked regularly according to the requirements of different sensors. The effective circle of deformation should be adjusted before use.induction welder.

6) If the position of the magnetizer is changed or other accessories are loose, etc., adjust it before using it.

The gear adopts high-frequency heating machine for quenching and tempering to heat treatment . Due to the influence of operating process and surrounding environment , it is easy to produce defects such as low hardness , uneven hardness and deformation . These defects can affect the service life of the gears , and the gears will be scrapped . induction heater.Therefore , it is very important to understand the causes and preventive measures of defects .

First. the causes and precautions of low hardness defects are as follows: 1. The carbon content of gear steel is low . For this reason , we should check the chemical composition of steel before heat treatment . 2. quenching heating specifications are not appropriate , for this , when using high-frequency heating machine quenching , we should adjust the quenching specifications . 3. The tempering temperature is low . For this , we should increase the tempering temperature .

Second. the causes of the uneven hardness defects and preventive measures are as follows: 1. The original steel structure is poor . For this , we should check the quality of the steel . 2. quenching and tempering heating temperature is not uniform , for this reason , we should improve the uniformity of quenching and tempering temperature .
