Improvement of Accuracy of Joining Single-Butt Links of Chains by Resistance Butt Welding.

Theoretical analysis of different methods of stabilization of heating of the shunting part of a blank and the welding joint is carried out. Practical methods of implementation of the proposed methods of improving the accuracy of resistance welding of single butt links of chains are indicated. It is shown that strictly set heating conditions of the shunting part of the blank and butt joint may be attained by using a new fast-acting drive of displacement of the mobile machine frame.
