Butt-welded technology is a kind of metal bonding by heating the workpiece to a melting or plastic state by the electrical current flowing through the contact surface. Working pressure under 4.0MPA that is available in refrigerant R410a.
Aluminum and copper
3003 and 6061
Butt-welded Copper Aluminum Connector is widely used for cold storage refrigerant systems. we provide the latest butt-welding technology to make sure zero leaks in evaporators operating.
We tested our fusion area at more than 6.9mm, after helium detection, no leak risk happens in working pressure 4.0Mpa. authorized patten N0:10-1925119.
Butt-welded refers to a method that applying pressure and heating by an electric current on weldment. when welding, no required filler metal, high productivity, and automation.
Butt Resistance welding is a method of forming metal bonding by heating the workpiece to a melting or plastic state by using the resistance thermal effect caused by the current flowing through the contact surface and the adjacent area of the workpiece.
