  What are the precautions for the use of resistance spot welding machine ?

  The resistance spot welding machine of Stech Technology refers to a kind of welding equipment that uses the principle of resistance heating to weld. Resistance spot welding machines can be divided into different types according to different uses and requirements. From the classification of welding methods, point welders, seam welders, projection welders and butt welders, etc.

  From the electrode pressure type, there are lever type, electric cam type, pneumatic type, hydraulic type and pneumatic and hydraulic combined type, etc.; from the welding current type of resistance spot welding machine, there are single-phase power frequency welding machine, secondary Class rectifier welding machine, three-phase low frequency welding machine, capacitor energy storage welding machine and inverter power welding machine, etc. The resistance welding machine is mainly composed of the main circuit part, the pressure transmission part and the control part.

  Precautions for the use of resistance spot welding machine:

  (1) Precautions for welding electrodes

  Electrode materials are commonly made of aluminum oxide copper (red copper), cadmium bronze, chromium bronze, tungsten alloy, etc.;

  The shape of the electrode is various, mainly determined by the shape of the weldment.

  When installing electrodes, pay attention to the appearance of the upper and lower electrodes to be parallel;

  The three-dimensional electrode should be kept clean, and it should be trimmed with emery cloth or file.

  (2) Precautions for welding process

  Welding cycle The welding cycle of spot welding and projection welding consists of four fundamental stages (spot welding process).

  Pre-compression stage-the electrode drops to the current-on stage, to ensure that the electrode is pressed against the workpiece, so that there is proper pressure between the workpieces.

  Welding stage-the welding current passes through the workpiece and generates a high temperature to form a nugget.

  Maintenance phase-cut off the welding current, the electrode pressure continues to be maintained until the nugget is condensed to a sufficient strength.

  Resting phase-the electrode is lifted until the electrode begins to drop again, and the next welding cycle begins.

  (3) In order to improve the function of the welded joint, it is sometimes necessary to add one or more of the following items to the welding cycle:

  Increase the pre-pressure to eliminate the gap between thick workpieces and make them fit tightly;

  Use the preheating pulse to improve the plasticity of the metal, so that the workpiece is easy to fit tightly and avoid splashing;

  Adjust the current or welding time to achieve the ideal welding effect for the welding workpiece;

  Doing so during projection welding can make multiple bumps evenly contact the plate before energized welding, so as to ensure the divergence of heating at each point.

  Resistance spot welding machine welding method-spot welding

  Spot welding is a resistance welding method in which the weldment is assembled into an overlap welding head and pressed between two cylindrical electrodes, and the base metal is melted by resistance heat to form a welding spot. Spot welding is mainly used for welding thin plates, wires, small hardware and other products. The process of spot welding:

  (1) Preload to ensure good contact of the workpiece.

  (2) Energize to form a nugget and plastic ring at the weld.

  (3) Power-off forging, so that the nugget cools and crystallizes under the continued pressure to form a densely structured solder joint without shrinkage or cracks.

What are the common problems in the welding of precision spot welders?
Common problems in the welding of precision spot welders: the welding point is not penetrated, and the welding spatters, which makes the spot welder unable to weld. Therefore, in actual use of the spot welding machine, the following items should be paid attention to.

The influence of the pressure of the intermediate frequency spot welder on the welding quality
In the actual intermediate frequency spot welding machine, adjusting the electrode pressure is one of the key parameters of spot welding. The nature of the workpiece adjusts the parameters and pressure. Excessive or too small electrode pressure will reduce the load-bearing capacity and dispersion of the solder joints, especially for tensile loads.

Introduction to the workflow of automatic battery spot welding machine
One is to adjust the effective value of the welding current to make the heat of the internal power source change significantly; second, due to the concentration and contraction of the contact points of the two weldments during the operation of the automatic spot welding machine, concentrated heating occurs there , And the plastic junction area first seems to form unevenly during spot welding plus this unfavorable factor
