Principle of Heat Pressure Welder(Upset butt Welder)

加熱圧接機2-1

The ends of the wire rods to be joined are butted together over a length (TD) of 2 to 2.5 times the wire diameter (φD) and then the wires are clamped. Initially, small pressure (P1) is applied to the butt section. After the squeezing period (t1),a large current (I) is applied to the section until a specified length (L1) of material becomes molten due to joule heat. Simultaneously,a high pressure (P2) is applied,which causes the excess molten material to be pushed out of the joint. After holding time (t2),the clamp is released to complete the operation.

Features

Applicable to a wide variety of materials

The heat pressure welders(Upset Butt Welder) have been designed primarily for use with high carbon steel wire rods that are normally difficult to join, and copper wires that are required to have high connection performance to cope with high-speed wire drawing machines. However, they can be applied to many other materials.

  • Aluminum wire rods for electrical conduction.
  • Flat wire rods for electrical conduction.
  • Brass wire rods.
  • Welding of stranded wires.
  • Welding of different types of metallic wires and rods.

High Performance of the Welded Section

With the heat pressure welding process, which is a two-step upsetting type, undesirable defects within the metal structure are eliminated when the excess molten material is forced out from between the joining surfaces. This feature assures unprecedented weld performance. In the case of high carbon steel is a rod, the decarburization and hardness loss typical of traditional processes will be reduced. In the case of copper wire rods for electric application, the welded section is less subject to the formation of overheat zone, oxygen absorption, or decrement in strength, unlike in the conventional process. These features are particularly useful in the welding of oxygen-free copper stock which must be protected against oxygen absorption of flat pieces that are subject to severe working conditions.

Finishing the welded section is very easy

A tip of special material attached to the end of the clamp section is used to remove the burr. This deburring is so efficient that the subsequent finishing operation takes a far shorter time than in the conventional method.

Skilled workers are not required

Automatic operation. Once the wire rods are clamped,no subsequent attention is required up to the deburring step. This assures uniform results regardless of the skill of individual operators.
