1. The role of the pre-pressure stage is to reduce contact resistance, increase conductive cross-section, and increase physical contact points, creating conditions for the smooth passage of welding current in the future; in addition, under the action of pressure, the plastic deformation caused by the extrusion of metal into the gap helps to form a transparent sealing layer around the nugget to seal the nugget.

The UN6 water-cooled pneumatic butt welding machine is a relatively complex resistance butt welding machine. Xinxing Welding reminds you that you must operate in accordance with this safety operating procedure. 1. When starting, turn on the water source, air source, and finally the power supply. 2. After the welding machine is powered on, it should be inspected first

Welding steel mainly depends on the carbon content to determine whether it can be welded or not. In order to ensure high-quality welded joints, Xinxing editor recommends giving priority to low carbon steel, and then medium carbon steel.
Read articleWhether it can be welded with the Xinxing flash butt welder depends on the type of steel? Steel is divided into: (1) Ferritic F steel (2) Austenitic (A) steel (3) Cementite Fe C steel (4) Pearlite (P) steel (5) Martensite (M) steel

The main workpieces that need to be tempered after flash butt welding are steel and copper. The function of tempering is to reduce the brittleness of the metal, eliminate or reduce internal stress, obtain the required mechanical properties, stabilize the size of the workpiece, and facilitate cutting. Xinxing editor also often sees direct tempering after butt welding.
