How the electrode affects the welding quality of medium frequency welder? [DCS16]
Jan 02,2024
The current density is determined by the contact area of electrodes in medium frequency welder. The resistivity and thermal conductivity of electrode materials are related to the generation and loss of heat, so the shape and material of electrode have significant influence on the formation of Nugget.
With the deformation and wear of electrode end, the contact area will increase and the strength of solder joint will decrease.
The strength of solder joint always decreases with the increase of electrode pressure. When the electrode pressure is increased, the welding current is increased or the welding time is prolonged to compensate for the decrease of the resistance and keep the solder joint strength unchanged.
The stability of solder joint strength can be improved by adopting this welding condition. If the electrode pressure is too small, spatter will come and the strength of solder joint will come weak.
