Know the influence of welding speed on welding, in order to better operate and adjust the high frequency straight seam welded pipe unit, in order to achieve higher efficiency. Today, let's take a look at the influence of welding speed on high frequency longitudinal welded pipe machine.
The forming speed of welded pipe unit is restricted by the high frequency welding speed. Generally speaking, the unit speed can be opened faster, reaching 100 meters per second. The speed of existing units in the world can even reach 400 meters per second. High frequency welding, especially induction welding, can only be below 60 meters per second, and steel plates exceeding 10mm can be formed. The forming speed of domestic unit production can only reach 8~12 meters per second. The welding speed affects the welding quality. When the welding speed is increased, it is beneficial to shrink the heat affected zone and extrude the oxide layer from the molten groove; on the contrary, when the welding speed is very low, the heat affected zone becomes wider, which will produce larger welding burrs and oxide layer Thickening, the quality of the weld becomes worse. Of course, the welding speed is limited by the output power and cannot be raised very high.
Domestic unit operation experience shows that the welding speed of 2~3mm steel pipe can reach 40 m/s, the welding speed of 4~6mm steel pipe can reach 25 m/s, the welding speed of 6~8mm steel pipe can reach 12 m/s, and the welding speed of 10~16mm steel pipe is below 12 m/s. The speed can be higher when contact welding and lower when induction welding.
