KHMA Series Saddle-shaped Pipe Submerged Arc Automatic Welding Machine

Product application

Applicable industries

KHMA application in boiler, pressure vessels, chemical plant, petroleum industry, repair, shipbuilding industries, etc.

Applicable scope

Equipment adopts digital control; realize nozzles and cylinder at the intersection of space curve motion, So as to realize the nozzles and cylinder welding with orthogonal, partial, skew etc seam welded.

MODEL:KHMA500A, 500B, 1000, 1600, 2000

SIZE: Various

KHMA series of orthogonal saddle-automatic submerged arc welding machine, dedicated to the tube diameter Φ100 ~ 2000 (mm) and orthogonal saddle-shaped cylinder automatic welding. Is carbon steel, alloy steel boiler equipment, and welding equipment important.

The machine consists of the power (selected according to user needs), control system and head and other parts.


The machine uses advanced inverter technology power supply and power units in parallel technology, a high success rate with arc welding process is stable, welding specification width, small size, light weight, strong ability to compensate for power fluctuations, etc.

The KHMA equipped with the company developed a control system, including the control box. Touch screen and the corresponding control software. Through the LCD touch screen control system and control panel, man-machine dialogue, you can easily set and adjust the process parameters, optimize the best process planning; process planning can prepare a good long-term storage, at any time.

KHMA is mainly used for round welding for the saddle-shaped or round-shaped pipes, outer diameter of the base part (Shell) scope is over 300mm, the scope of outer diameter of welding pipe is 100mm-2000mm, KHMA make the all position welding is possible, tidy welding seam forming, high quality, highly automation, It is an ideal equipment for welding pipes

Function and characteristics

1, Adopting advanced modular design, the power can be based on user actual need choice.

2, AdoptingPLC control systemand industrial control module, the machine has the strong anti-jamming.

3, Canstored up more than 48 group welding standard,each group of welding procedure can be divided into 1 ~ 8 section, achieve fine welding process control.

4, Industry-specificLCD touch human-machine interface, make operation simpler, and not need professional basis and special language. Through the control system of LCD touch screen and control panel, convenient realization man-machine dialogue, setting and adjust every process parameters, select the best technical process, and will prepare good craft standard long-term storage, facilitate always accessible.

5, Can from arbitrary position start of weld, easy to use

6, Realize dynamic control of welding process, groove size neat through dynamic process parameters fine-tuning also can get good quality welds.
