Small AC resistance welding machine for copper welding

Explanation of butt welding machine

Butt welding is a method of welding where the weldments are placed separately between two clamping devices so that their end faces are aligned and the contact is electrically heated. Butt welding requires the same or similar cross-sectional size and shape at the contact area of the weldments to ensure uniform heating of the contact surface of the weldments. Butt welding is mainly used in the manufacture of closed parts (e.g. bicycle rims, steel windows, etc.); rolled steel joint lengths (e.g. steel town, steel pipes, steel bars, etc.). Welding of dissimilar materials (e.g., butt welding of dissimilar materials to save valuable materials and increase the life of the working part of the tool). Butt welding is widely used because of its high productivity and ease of automation.

Copper and aluminum rod butt welder

It consists of a single-phase welding transformer, welding fixture (eccentric and spiral type), body and electrical configuration, etc. (Refer to other descriptions of UN series for use and maintenance. (Use and maintenance refer to the UN series of other instructions, appearance with the UN-16.) The welding diameter is 5-15mm for mild steel, 4-8.5mm for copper, 6-14mm for aluminum. 

The UN-20 butt welding machine is specially made according to the current customer's requirements for welding 8mm diameter low oxygen copper rod. It is used for welding copper rods and also plays an effect of saving electricity. Its structure mainly consists of single-phase welding transformer, welding jigs (eccentric and spiral type), the body and electrical configuration. (Use and maintenance refer to the UN series of other instructions, appearance with the UN-16.) The welding diameter is: mild steel 5-15mm, copper 4-8.5mm, aluminum 6-14mm.
