Brief Introduction:

KHB12—80 Tube to tubesheet automatic orbital welding machine is specially used for automatic welding of tube-tubesheet with outer diameter of tube diameter from 12mm to 80mm, including flat end connection (flat welding) and outreach angle connection (outer fillet welding). It is also suitable for welding methods without filling and filling. It adopts argon arc welding method, which has beautiful weld seam and excellent welding quality. The welding torch can be adjusted circumferentially, axially and radially. The whole machine is compact in structure, light in weight and convenient and reliable in adjustment.

Product advantages


1. Mature technology and advanced technology

23 years of experience in intelligent welding equipment technology R & D and manufacturing, multi-generation product process accumulation and upgrade,compact machine head and small in size, adopts elastic positioning mandrel and three-point support frame, which can be adjusted circumferentially, axially and radially, and the operation is fast. accuracy in positioning.


2. Imported motor, stable and reliable

The IGBT inverter is used to control the DC pulse current, the welding efficiency is high, the arc stability is strong, and the bead is beautifully formed.


3. Operating economy, efficient production

The TIG water-cooled welding torch is equipped with a 16-liter stainless steel water tank, which is not limited by the on-site water pressure and other conditions. The cooling is sufficient to ensure that the welding machine can work 24 hours a day.


4. Easy to control, easy to use

The program control system is easy to operate and can store up to 100 welding specifications. Each group can be divided into 1 to 16 segments. It can be operated with simple training without special foundation and special language. The truck-mounted integrated design is free to move and easy to use.


Working principle


After completing the welding program setting on the control box panel, insert the machine head into the working position, press the start button on the remote control, the welding machine starts the arc, and the current gradually rises from the arcing current to the welding current. The welding does not rotate and not feed wire either at this time, the purpose is to preheat the tube sheet, which can be controlled by rising the time parameter. When a stable molten pool is formed on the workpiece, the torch begins to rotate and the wire feed begins simultaneously. The wire feed speed is adjustable from 0 to 1.5 m/min. During the rotation process, there will be flat welding, downslope welding, overhead welding, upslope welding, etc at some time. This welding machine allows the user to set any segmentation of 1~6 segments within 360° according to the situation, and set them separately. Through setting up welding speed, current size, wire feed speed and other parameters of each section, the weld is consistent overall. When the welding torch rotates 365° (the lap angle can be set arbitrarily), the welder enters the attenuation program. At this time, the machine head continues to rotate, but the wire stops feeding, and the current gradually decreases from the welding current to the arcing current, forming a weld seam. This process can be controlled by entering the fall time parameter. The welding process of the entire nozzle is automatically completed according to the setting procedure after pressing the start button.
