Automatically arc weld the L seam or straight seam of ladder or pipe fittings or plate and so on


1.The finished product has a good appearance. Ensure that the welding specifications are even and flat, and the operation is simple and reliable. The quality can meet the welding requirements.

 5 Axis CNC welding ladder

2.CNC welder can use MIG/MAG/TIG welding with automatic feeding wire system.The short-distance push-wire mechanism is to ensure the wire feeding stability.

  1. 3.5 axis automatic seam welder use Japan OMRON PLC and 5 axis CNC control system to control and achieve the welding process, improve reliability.

4.The welding type and welding specification can be preset, stored and recalled via the Teaching pendant screen. It is convenient to change parameters and state conversion on the touch screen 

5.The machine equipped with the function of high voltage, slow wire feeding and arc ignition to ensure reliable arc ignition, as well as low voltage and low current arc closing and arc crater filling functions.

6.Before welding ,adjust the welding torch position.During the welding, the workpiece is fixed ,and the welding torch is drive by motor to move left and right on the guide rail ,the speed is adjustable to ensure consistent welding. After welding,the welding torch return the original point automatically.

7.This seam welding machine consist of mainframe, welding torch 5 axis adjust mechanism,electrical control system, pneumatic system and welding power source with push type wire feeder.

8.The machine body adopts the cold bending and welding of webs and guide rails to reduce welding seams, improve the strength and appearance of the entire column, reduce the welding heat affected zone, and reduce the damage to the excellent characteristics of steel. After welding, stress relief is adopted to ensure the mechanical properties of the column

Welding torch 5 axis adjust mechanism

0.1 Right and left moving mechanism :

The column is driven by AC servo motor. With the help of serve motor reducer and rack &pinion,the column move on the guide rails.

10.2 Up and down moving mechanism:

The beam is driven by AC servo motor. With the help of serve motor reducer and ball screw,will move on the guide rails which installed on the column 

10.3 Forward and backward moving mechanism:

The beam is driven by AC servo motor. With the help of serve motor reducer and rack&pinion,the beam will move on the sliding plate 

10.4. Welding torch rotation mechanism:

It is driven by AC servo motor. The angle of mechanism can adjusted manually, and locked tightly.

10.5 Welding torch adjust slope angle

It is driven by stepper motor. The angle of mechanism can adjusted from 0~60°
