KHGT pipe to pipe butt welding machine

KHGT desktop type automatic orbital welding machine is specialized for straight tube butt welding work with or without wire filling automatically(pipeline fabrication, pipeline producing). According to different needs, can be used for tube to tube, tube to sealing cap, tube to flange, and so on, according to the different thickness requirements, we can use different ways, such as cold welding wire, hot wire TIG welding TIG welding or TIG welding way. + MIG.

Application:

Petrochemical, boiler, refrigeration, medicine, aviation, pressure vessel, ship, food machinery, atomic energy, etc.

Advantage

Suitable tube sizes: Normally 19 - 80mm
Suitable material: carbon steel, stainless steel, alloy steel, and so on.
KHGT have OSC/AVC functions - with oscillation OSC and arc voltage control AVC.
KHGT could solve the issue of operator error in gas tungsten arc welding(GTAW/TIG).
KHGT is composed of the power supply,control system,cooling system, wire feeding system, and the welding head working station.

KHGT can rotate freely infinite at any angle of 360°.

KHGT is widely adopted in pipeline fabrication, pipeline producing.
Driving and wire adopts reliable stepping motors.
Suitable for various kinds of pipe - pipe joint way, and various groove form
Starting main components are used aviation materials, light weight, size stability, and high temperature deformation
24 hours continuous welding- Welding torch using forced circulation water cooling, can work long hours. Mandatory water cooling system, equipped with 16 liters stainless steel water tank, not affected by field water hydraulic conditions of limits, cooling fully, reliable convenient.
Intelligent welding- PLC control system and LCD touch human-machine interface, can be stored up to 100 groups of welding programs, each group of welding scope can divide 1-2 section, input is simple, do not need professional basis and specialized welding knowledge.
Using Panasonic IGBT inverter control DC pulse arc welder, high efficiency, arc welding strong stability, finished weld seam have a beautiful and strong effects.
