Spot welding machine welding stress changes and curves

In the early stage of the medium frequency spot welding machine, due to the effect of welding pressure, the grains with similar crystallization directions and stress directions first cause movement. As the welding current cycle continues, the solder joint displacement occurs. Until the solder joi... Read More

The Capacitor of Energy Storage Spot Projection Welding Machine

The device that stores charge in the energy storage spot welder is a capacitor. When the charge is accumulated on the capacitor, a voltage will be generated between the two plates. Capacitance describes not the amount of charge stored in the capacitor, but the ability to store charge. How much ch... Read More

What factors are related to the effect of energy storage spot welding machine?

What factors are related to the effect of energy storage spot welding machine? Let’s take a brief look at: 1. Welding current; 2. Welding time; 3. Electrode pressure; 4. Electrode raw materials.     1. Influence of welding current It can be seen from the formula that the impact of curr... Read More

Is the welding circuit of medium frequency spot welding machine important?

Is the welding circuit of medium frequency spot welding machine important? The welding circuit is generally composed of the secondary winding of the solder resist transformer, hard conductor, soft conductor (composed of multiple layers of thin pure copper sheets or multiple sets of multi-core cop...

The Importance of Safety Grating for Medium Frequency Spot Welding Machine

When the medium frequency spot welding machine is working, the welding pressure is hundreds to thousands of kilograms instantaneously. If the operator works frequently and does not pay attention, crushing events will occur. At this time, the safety grating can come out and be installed at the loc... Read More

How to control the welding quality of Capacitor Discharge Spot Welder?

Although Capacitor Discharge Spot Welder are suitable for multi-point welding, there will be big problems if the quality is not up to standard. Since there is no online non-destructive welding quality inspection, it is necessary to strengthen the management of quality assurance.     Pr... Read More

What is the preload time of medium frequency spot welding machine?

The preloading time refers to the time from when we start the switch – cylinder action (electrode head action) to pressurization, which is called preloading time. The sum of the preloading time and the pressurizing time is equal to the time from the cylinder action to the first power-on. I... Read More

Why is chrome zirconium copper the electrode material of IF spot welding machine?

Chromium-zirconium copper (CuCrZr) is the most commonly used electrode material for IF spot welding machine, which is determined by its excellent chemical and physical properties and good cost performance. Electrode is also a consumable, and as the solder joint increases, it will gradually form a... Read More

Influence of welding time of IF spot welding machine on electrode pressure?

The influence of welding time of IF spot welding machine has obvious influence on the total resistance between two electrodes. With the increase of electrode pressure, R decreases significantly, but the increase of welding current is not large, which cannot affect the reduction of heat generation... Read More

How to maintain electrode of IF spot welding machine?

In order to obtain high-quality welding spot quality, apart from electrode material, electrode shape and size selection, IF spot welding machine shall also have reasonable use and maintenance of electrode. Some practical electrode maintenance measures are shared as follows: Copper alloy shall be... Read More

Why is the current unstable during spot welding of IF spot welding machine?

We will encounter some problems when operating the IF spot welding machine. For example, the welding process is caused by unstable current. What is the cause of the problem? Let’s listen to the editor. Inflammable and explosive articles such as oil, wood and oxygen bottles shall not be sta... Read More

How to check the use of intermediate frequency spot welding machines?

The intermediate frequency spot welding machine needs to regularly inject lubricating oil into various parts and rotating parts, check the gaps in the moving parts, check whether the matching between the electrodes and electrode holders is normal, whether there is water leakage, whether the water...
