    What are the key points of hydraulic quick coupling welding technology?

    hydraulic quick coupling

    The transverse shrinkage of hydraulic quick coupling is related to the weight of weld metal per unit weld.  As the resistance of the weld increases with the increase of the amount of metal in the weld, the shrinkage produced in the first few steps of welding is larger, while the shrinkage produced in the next few passes of welding is gradually reduced.


    (1) With the increase of root clearance, the transverse shrinkage of root clearance n increases obviously, because when the root clearance increases, the total amount of welds increases.


    (2) groove type. Experiments shows that the butt joint with single V-groove will produce greater transverse shrinkage than that with double v-groove, partly because of the larger cross-sectional area of the weld with v-groove. 


    (3) Electrode diameter. With the increase of electrode diameter, the transverse shrinkage decreases. However, unless large diameter electrode is used in Shaoyi weld, the transverse shrinkage will not be reduced by increasing the diameter of electrode. the basic welding process of hydraulic quick couplings and pneumatic quick couplings are the same.
