BS EN ISO 5183-1:2001 – Resistance spot welding — Electrode adaptors, male taper 1:10 — Part 2: Parallel shank fixing for end-thrust electrodes
1 Scope
This part of ISO 51 83 specifies the dimensions and tolerances of resistance spot welding electrode adaptors where the fixing element for the cap (see ISO 5821 ) is a male taper of 1 :1 0 and a parallel shaft is used to fix the adaptor to the electrode holder in accordance with ISO 8430-3.

3 Dimensions
The dimensions shall be those given in Figure 1 and Table 1 .
4 Designation
The designation of electrode adaptors which comply with this part of ISO 51 83 shall include the following:
a) the description block (i.e. “spot welding electrode adaptor”);
b) reference to this part of ISO 51 83, i.e. ISO 51 83-2;
c) the type of electrode adaptor, in accordance with Figure 1 ;
d) the diameter, d 1 , in millimetres;
e) the length, l 1 , in millimetres;
f) the material of which the electrode adaptor is made, in accordance with ISO 51 82.
EXAMPLE A type C spot welding electrode adaptor, of diameter d 1 = 1 6 mm, length l 1 = 68 mm and material type A 2/1 ,shall be designated as follows:
Spot welding electrode adaptor ISO 5183-2 – C – 16 ? ? 68 – A 2/1
5 Materials
The material of which the electrode adaptor is made shall be in accordance with ISO 51 82:1 991 , preferably group A, type 2.
6 Marking
Electrode adaptors complying with this part of ISO 51 83 shall be marked with the designation laid down in clause 4,but excluding the description block and the reference number of this part of ISO 51 83, e.g.:
A – 16 68 – A 2/1
