，也要做到焊接方法規(guī)定！
4、電焊焊接電級(jí)：在突點(diǎn)電焊焊接全過程中，左右電級(jí)的平面度是十分關(guān)鍵的，假定電焊焊接電級(jí)高低不平，電焊焊接電流量會(huì)先穿過碰的地區(qū)，電流量會(huì)過度集中化在高地址上，導(dǎo)致突點(diǎn)遍布電流量不勻稱，進(jìn)而造成濺出，危害外螺紋！

根據(jù)之上4點(diǎn)，大伙兒懂了焊接螺母是能夠保證無需回牙的

！要是有好的自動(dòng)點(diǎn)焊機(jī)，有技術(shù)專業(yè)的焊接方法師及系統(tǒng)軟件的學(xué)習(xí)培訓(xùn)，這種都能夠降低和防止的。

Many customers will say that my automatic spot welding machine returns teeth when welding the nuts, and I don't know what the reason is. Rongshijie manufacturers will come and explain to everyone.
The key of automatic welding nut refers to the welding of metal sheet and full-automatic bump welding. The key of electric welding method is to choose the resistor hot-melt welding. To fully automatic multi-external threads welded by electric welding will not damage and will not return teeth. The key is 4 factors:
1. Welding working pressure of automatic spot welding machine: The welding working pressure of automatic spot welding machine is very related to the welding welding cylinder control board relay. The cylinder of Rong Shijie automatic spot welding machine uses well-known brand cylinders, plus imported solenoid valves To ensure the stability of the working pressure during the entire welding process of the automatic spot welder. It is assumed that the cylinder steering headlights are not good. At the moment of automatic welding, it is assumed that the cylinder steering headlights are not good. Immediately, the electric welding welding will be spattered. If the splashes enter the external threads, the external threads must be returned to the teeth.

2. Electric welding welding current, in the case of welding nuts, most of the fully automatic are with bumps, the reliability of the electric welding welding current quantity, can reasonably block the welding spatter, automatic spot welding machine The use of an independent intermediate frequency AC and DC power supply, manipulating the welding time of ms, has the characteristics of fast welding speed and stable output current, which ensures the reliability of welding quality!
3. The adjustment of the main parameters of the welding method. In the case of adjusting the main parameters of the welding method, if the welding current is adjusted to be too large or the time is too long, it will affect the external thread of the welding nut. When you choose Rong Shijie's automatic spot welding machine, Rong Shijie's process engineers will adjust the main parameters of the appropriate welding method in accordance with your product processing technology regulations to ensure the external thread is also based on the welding method regulations!
4. Electric welding level: In the whole process of bump welding, the flatness of the left and right electric levels is very critical. Assuming that the electric level of the electric welding is uneven, the electric current of the electric welding will pass through the area where it touches. Excessive concentration on high addresses, causing uneven currents across the bumps, causing splashes and damaging external threads!
According to the above 4 points, everyone understands that welding nuts can ensure that no back teeth are required! If there is a good automatic spot welder, and there is a professional training of welding methods and system software, this can be reduced and prevented.
