Measures to overcome nugget offset of intermediate frequency spot welding machine

Measures to overcome nugget offset of intermediate frequency spot welding machine

Under normal conditions, when the intermediate frequency spot welding machine is welding with different thicknesses and materials, the nugget will not be offset to the thick plate or the weldment with poor electrical and thermal conductivity due to the symmetrical bonding surface. As a result, the size on the bonding surface will be lower than the nugget diameter. At the same time, the penetration rate on the thin part or the weldment with good electrical and thermal conductivity will be lower than the specified value, which will reduce the bearing capacity of the solder joint.

Solution to Common Problems of Pack Battery Automatic Spot Welding Machine

Solution to Common Problems of Pack Battery Automatic Spot Welding Machine

1. No display on the boot LCD screen. If you encounter this situation, you must first reflect on whether you can stop energizing the pack battery automatic spot welder. If you ensure that the power is on, but it is still not displayed, it may be a power failure. We can reflect on the power line to see if there is a short circuit. Maybe the safety tube was burned. If this is the problem, we only need to change the insurance tubes of different specifications.

Shenzhen STE Technology: What are the advantages of battery spot welding machine?

The 1. battery spot welding machine adopts DC output: the current of the battery spot welding machine is pulsating DC, and its wave ripple is very small, there is no AC zero and discontinuous heating shortcomings, can achieve a highly concentrated state, so that the thermal efficiency of welding can be improved. It is especially suitable for the welding of non-ferrous metal materials and some difficult-to-weld materials. The welding process is stable and the welding quality is significantly improved. The electrode life can be extended accordingly.

Spot Welding Machine Manufacturer: Introduction to Benefits and Methods of Cleaning Weldments Before Welding

Spot Welding Machine Manufacturer: Introduction to Benefits and Methods of Cleaning Weldments Before Welding

The contact resistance value of the cleaned weldment surface increases with the increase of storage time. Because the cleaned weldment surface is oxidized under the same storage condition, when the storage time is not long, the newly formed oxide film on the surface is thin and uniform, which has little effect on the welding quality. If the storage time is too long, the oxide film will thicken and cannot be welded. Therefore, for oxidized materials, the time elapsed from surface cleaning to the end of welding must be strictly controlled. The length of storage time depends on the type of material, surface cleaning method, storage environment and quality requirements.
