​Flash butt welding is widely used for the longitudinal connection of steel bars and the welding of prestressed steel bars and screw end rods. The principle of flash butt welding of steel bars is to use a butt welding machine to bring the two steel bars into contact with each other. After the steel bars are heated to a certain temperature and softened by a strong current of low voltage, they are subjected to axial pressure upsetting to form a butt welded joint.

When the wood flakes are skewed relative to the positioning line, the hdpe jointing machine can adjust the angle by means of a yaw drive member arranged on the base. This is one of the reasons why many people choose hdpe jointing machine.

​Hdpe pipe welding machine is used in electrical, aviation, medical, and other fields. With the improvement of technology, various types of electric melting machines have been produced to meet the work needs of different industries and different scenarios, greatly improving the quality of products and work efficiency, and becoming an indispensable part of people's production and life.

​The manual butt welder has small size, simple operation and low price. In the work of steel welding, if the strength requirements are high, it must be polished, if the strength requirements are not high, it can be that the joints are less melted.

​The plastic pipe butt welders usually refers to the connection of Haval sleeves. For example, HDPE pressure pipes used in common gas pipes and water supply pipes are usually welded by electric heat fusion pipe fittings. Of course, there are also welding using heat fusion butt welding machines. When the pipe surface is damaged, the plastic extrusion welding gun is usually used as a repair tool, but it is limited to small repairs. After all, such pipes are usually pressure-bearing pipes and need to be safe and reliable.
