FAQ

Mm 0.2 enameled wire and copper welding, with spot welder good. Better with laser welder. Now the parts are machined with micro spot welding machine. Pressure and current are not good control, welding quality is not good, not welding is not strong, it will break.

Enameled wire is not good, if the copper sheet can be bent a hook, the enameled wire will be placed in the middle of the hook, and then welding with a common touch welding machine will be fine.

The spot welder often stops itself and points out that the spot welding is not finished and needs to be done manually. Why is that?

The general problem is the control system

Our company is the production of mobile phone antenna, the antenna is composed of each section of small shaft assembly, a small shaft is connected by tubes with pin and connected together, the problem is due to the shaft diameter is relatively small, the pin diameter is smaller, the pin will be riveting is not strong, so I want to use it directly to spot welded together, do not know who can recommend a more suitable for our company specifications of spot welder. The diameter of our company's pin is between 0.6mm-1.2mm. There are recommended best. Please specify the performance, price and so on. Thank you all for the good plus 100 points as compensationThe pipe head hole size and outer diameter are 0.9 and 0.7 respectively. It is necessary to use spot welder to weld him to the pin. The time is urgent. I hope someone who knows the matter will contact me immediately

Send some work. I'll try the welding below

Why is there any spatter in spot welding machine? How to solve?

In the process of welding, the interface of the welding rapidly melts in a short time, the metal heat increases instantaneously, and the molten liquid can not be cooled,Under the action of pressure, the liquid ejected from the nugget and produced a splash.Produce heat publicity Q=I2RT, we know that when the heat is too high, easy to splash. Therefore, the spatter can be controlled from the angle of current and resistance.Current density: the workpiece surface has dirt or gap between the workpiece, the current density increases, splash increasesThe electrode cap is asymmetrical or worn, the current density is increased, and the spatter is increasedElectrode pressure: electrode arm prevents electrode misalignmentReasonable welding stress controlled by electrode pressureWelding parameter: current control, reasonable welding currentPower on time, reasonable timeFluctuation of power grid prevents fluctuation of current caused by fluctuation of power supply

Customers who need batteries and series automatic spot welders can contact Dongguan three edge automation

Spot welding power supply can be used as "characteristic welder" to recognize the sign "Styler". This is authentic.

How do you make a simple spot welder with several 10000uF-250V capacitors?

Small 220V power transformer one, 300W or more, the bigger the better, the price is about 100 yuanRelay oneInching switch oneTwo barWelding ability1.5mm+1.5mm steel, aluminium, stainless steel plate

That is, welding nickel belt, that spot welder, can not be used to weld electronic components, why?I think the copper clad copper foil is too thin, want to replace with a thicker wire, I shed technology does not pass, often for appearance of a solder joint tangled for a long time

Yes, it does matter. Just on the pressure, it won't passYou can try to use good wire and welding aidsThe degree of beauty is mainly the first line of welding wireYou calculate the melting point, wire thickness

Control principle of spot welder?

Belonging to a welding machine in resistance welding, resistance welding is divided into four forms: welding spot welding, projection welding, butt welding, seam welding. As a result of wide range of applications, the form of direct, so we are accustomed to welding machine collectively. So you ask the spot welding control principle, in fact, is the principle of resistance welding.Resistance welding is a method of welding the workpiece by applying pressure through the electrode and using the resistance heat produced by the current passing through the contact surface of the joint and the adjacent region.The physical essence of resistance welding process, is to use a lot of energy of plastic deformation and resistance to heat and the welding zone itself, so close to the lattice distance form the metal bond between the metal atom two separation performance, to produce a sufficient amount of grain in the combined surface and get the weld joint of solder joints, or. Resistance welding is a welding quality stability, high production efficiency, easy to realize mechanization, automation of the connection method, widely used in automobile, aerospace, electronics, household appliances and other fields.
