METHOD OF CONTACT FLESH WELDING OF ROUND SECTION ARTICLES AND FLESH TRIMMING Russian patent published in 2011 - IPC B23K11/04 B23K37/08 

FIELD: process engineering.

SUBSTANCE: invention may be used in welding round section articles at special-purposes welding machines mounted in drawing shops for integration of wire coils or for jointing reinforcing bars in construction. Ends of welded parts are fitted in electrodes of stationary and moving clamps provided with chilled steel semi-bushes with sharp edges arranged on opposed sides. Welding transformer is switched on to shift moving for fleshing off and precipitation. Fleshing off is conducted at increased welding voltage. After precipitation for preset allowance and transformer switching off, electrode clamping force is decreased at one of clamps till welded article slippage to cut off flesh heated in welding by aforesaid sharp edges of steel semi-bushes.

EFFECT: higher efficiency and precision of aligning faces.
