How to install gas and liquid containers in spot welders

【summary】 The strength of the welded joint will be reduced. Factors such as oxides, dirt, oil and other impurities affecting the surface of the workpiece make the contact resistance high.

The strength of the welded joint will be reduced. Factors such as oxides, dirt, oil and other impurities affecting the surface of the workpiece make the contact resistance high. About how the diameter of the flux cylinder of the welding machine should be mastered In order to better introduce the spot welder, ultrasonic metal welder, battery equipment, lithium battery special equipment, energy storage spot welder, automatic spot welder, AC spot welder, automatic spot welder for capacitor lead-in sheet, automatic spot welder for lithium battery type, automatic spot welder, automatic spot welder, automatic spot welder for AC parallel automatic spot welder, and so on, we will continue to introduce new knowledge and help you to better learning.

Because of its small size, simple operation, easy to use, fast speed, welded seam after welding and other advantages are widely used in various fields, especially for the requirement of high strength of the parts is particularly practical, can be in an instant will be the same kind of metal materials (or dissimilar metals) coupled together, just welding method is different) for the connection, the weld is heat-treated, the strength of the weld and the base material is comparable to the sealing of a good seal, which solves the problem of gas and Liquid container storage and transportation problems. In the aging furnace, the electrode contact area determines the current density, the resistance and thermal conductivity of the electrode material are related to the generation and dissipation of heat, and the electrode shape and material have an important influence on the formation of the electrode melt core.

Welding head deformation and wear makes the contact area of the welded joint is large, the strength of the welded joint is reduced; affect the surface of the workpiece oxides, dirt, oil and other impurities and other factors make the contact resistance is large. Oxide layer is too thick may even make the current can not pass. Because the current density is too high, the local conduction will produce spatter and surface burns. The presence of the oxide layer also affects the unevenness of the heating of each welding joint, resulting in fluctuations in weld quality. Therefore cleaning of the workpiece surface is necessary to obtain a high quality connection. Spot welders are heat-balanced and heat-sinking welds in which only a small portion of the heat generated is used to form the welded joint.
