How To Prevent Spatter In The Early Stage Of Spot Welding

Spattering of the spot welder during the welding process may affect the strength of the welding spot and cause damage to the operator. So what should we do in the project to prevent spattering in the early stage of spot welding? Next, our spot welding machine manufacturers will briefly introduce it for us. We need to strengthen the finishing of the spot welder, and clean the spot welder table and the welding object before and after each use to ensure that the welding object is neat and clean.

Pay attention to the preload during the welding process. If possible, it is recommended to use a preheat current to slow down the heating speed. When using the spot welder, the spot welder is not cleaned up. We must pay attention to the cleaning of the work piece of the spot welder, so that the welding will be better.

It may be because the pressure on the touch surface of the spot welder and the welding object is unevenly distributed, resulting in excessive current density in some parts, and then leading to the early melting of the welding object, which leads to the occurrence of spatter. If spatter occurs in the later stage of spot welding, what is the reason? This may be because the pressure during spot welding is too high, exceeding the range of electrode pressure, causing the plastic ring to break through and forming a spatter. At the moment of energizing and reducing the current to avoid splashing.
