Equipment for spot welding galvanized sheets
AGERA’s galvanized spot welding machine uses a DC power supply et MFDC technology, which has a small thermal impact on welding and can reduce overheating of the main cable. This type of welding equipment can also reduce electrode wear, eliminate the need for frequent electrode replacement, and effectively improve welding stability. The power of AGERA’s galvanized sheet spot welding machine is available from 75KVA to 1000KVA, and can be used to weld galvanized sheets or galvanized parts of different thicknesses.
Some of The Welder Model
-
This low-power machine can only weld small galvanized parts of about 1 mm and comes with a workbench for convenient placement of workpieces.
-
This welding machine can be used for spot welding and projection welding, and can easily weld galvanized sheets or galvanized nuts.
-
It can be used for ring projection welding of large galvanized explosion-proof nuts or other large contact surface welding with high current output.
Parameter settings for spot welding of galvanized sheet
The main welding parameters that affect spot welding of galvanized sheet are welding current, welding time and welding pressure. Since the galvanized sheet has a zinc layer, we need to set two current modes. The first mode uses a small current and a long time to melt the galvanized layer. The second mode uses a large current for instantaneous welding. In addition, the welding pressure cannot be set too small, which is easy to produce spatter and affect the appearance.
Precautions when spot welding galvanized sheet
First, we need to clean the workpiece et remove surface stains or oxide layers to avoid welding defects. In the process of welding galvanized sheet, we must pay attention to controlling the welding temperature to prevent the zinc layer from melting and affecting the welding quality. In addition, we must also pay attention to the maintenance of the electrode, regularly check the electrode wear, and replace the electrode in time.

Because the melting point of the zinc layer of the galvanized sheet is low, while the melting point of the base material is high. If you use an AC spot welder to weld, you can only set the welding current once. Therefore, although the zinc layer is melted, the base material is not completely fused. Only using our soudeuse par points à courant continu is the best choice for welding galvanized sheet.
It may be caused by improper parameter settings, too long current output time, or oxidation and corrosion at the welding position.
You can use our ADB-130 DC spot welder, which has a rated capacity of 130KVA and can weld 2-3mm thick galvanized sheet.
Although there will be more spatter if the welding pressure is too low, the pressure should be controlled not to be too high. Excessive welding pressure is prone to indentation, affecting the appearance and even crushing the joint.
