squeezing roller is to squeeze the edge of the tube which has been
heated to welding temperature, by squeezing rolls giving a certain
pressure to achieve welding purpose. Welding bead cutter is used to scrap weld seam and remove external
burr. It is made up of two cutters for using alternately. If one is
damaged, the other one will take the place to scrap. Scrapers can
be adjusted and have the quick lift function by cam. There are two
supporting roller underneath knife rest, in order to bear the
overdraft of scraping.and after the bead cutter with one horizontal
stand for polishing. |

Composition of stainless steel all in one integrated welder
System composition
The solid state high frequency all-in-one welder consists of 5
parts: SCR all-wave rectifier, IGBT high frequency inverter +PWM
voltage regulator, high frequency transformer, FRED quick recovery
diode module high frequency rectifier, E-bridge inverter output.The
rectifier +PWM AC voltage regulation is completed by one circuit
board.PWM control unit board is embedded on the main board. Main
functions of the unit board are completed by the single-chip
computer +PWM control system. Voltage adjustment and feedback
control are completed by combining with the double closed loop PI
regulator of the main board.Alarm control by digital circuit as the
control core combined with hardware fast response makes the
protection action sensitive.
The solid-state high frequency all-in-one welder adopts the
full-wave rectification IGBT inverter regulation mode, and does not
need the phase shift angle adjustment of SCR.Therefore, it has the
advantages of high power factor and good power saving effect also
reducing the cross section area of inputting cable.
Brief Introduction of Solid State HF Welder
