ADJUSTABLE MOVING COPPER SHOE FOR MULTIPLE PASS ELECTRO GAS WELDING

摘要

A functional copper shoe for multi-layer electro gas is provided to secure the property of the weld metal and weld heat-affected zone while maintaining the high productivity. A functional copper shoe for multi-layer electro gas(50) comprises a receiving part(51a) formed in a main body(51); a coolant circulation port(52) cooling the deposit metal; a stopper fixing the copper shoe in the extrusion and the insertion state; and a wheel(54) installed in both sides of the main body in order to minimize the frictional force generated between the main body and base material.
