This standard specifies the dimensions and tolerances of convex electrode caps for resistance spot welding. The axial taper of the electrode cap enables the electrode cap to be fixed on the internally taper electrode joint and to be fixed to the electrode holder. This standard applies to convex electrode caps for resistance spot welding under general use conditions. This standard is used in conjunction with JB/T9959-1999 "Electrode joints with internal taper 1:10 for resistance spot welding".

The axial taper of the electrode cap enables the electrode cap to be fixed on the inner taper electrode joint and to be fixed to the electrode holder. This standard is applicable to convex electrode caps for resistance spot welding under general use conditions. This standard is used in conjunction with JB/T9959-1999 "Electrode joint with inner taper 1:10 for resistance spot welding". Note: The maximum electrode pressure Fx of the convex electrode cap specified in this standard should not exceed 4kN. Cited standards

For example: the L-shaped convex electrode cap with an outer diameter of 16mm and a length of 25mm should be marked as: Convex electrode cap JB/T9960--L16×25
Note: The text part and the number of this standard can be omitted on the finished product of the convex electrode cap. Example: L16×25
Note: The other dimensions of the M and N type electrodes are alternate with the L type. 6
