KH-315A Orbital Welding Machine
KH auto pulse argon arc orbital welder can realize auto welding of KHGK Caliper tube - tube, KHGC closed tube-tube and KHB12-80 suspension tube plate. It adopts advanced inverter power supply, self-designed control system and accordingly control software.

Application:

Boiler, heat exchanger, pharmaceutical, chemical, food machinery, engineering installation, industrial pipeline, biological engineering, refrigeration engineering, electronic equipment, instrumentation ships, military industry, nuclear power, etc.

Parameter:

Power: 50/60Hz, single phase Power control mode: IGBT inverter control Rated input voltage: AC 200/220V ±10%(380V, 3 phase available ) Welding current(base current): 4~300A
Advantage
1.To addresses the issue of operator error in GTAW / TIG . computer-controlled process runs with little intervention from the operator. 

2.Three-in-one Multi-function, It is wildly used for KHGK, KHGC, KHB12-80 series 11 different type of orbital welding heads.

3.To guarantee high quality repeatable welding. a successful programming monitors variables and performs periodic samples during its test welding. LCD touch screen, easy to input.

4.Intelligent welding . 100 successful programming stored in PLC, just pick one. 

5.High productivity.  2-3 times higher than conventional TIG welding.
 
6.10 hours continuous welding. qualified welding head and power and water cooling system make it.

7.Car-integrated design, freedom of movement.

8.Small space of scientific design


















 


 

















KH-315A Multi-function Automatic TIG welder is a power source with Multi-function control system, which suits for KHGC, KHGK and KHB12-80 series various of tube orbital welding heads and Tube to tube sheet orbital welding head.

1)KHGK series open-frame orbital welding heads are used to weld tube OD 16mm - 300mm, and the tube wall-thickness is 1.5mm - 20mm.

2)KHGC series closed- frame orbital welding heads are used to weld tube OD 3mm - 180mm, and the tube wall-thickness is less than 3mm.

3)KHB12-80 series Tube to tube sheet orbital welding head is used to weld tube to tube-sheet, the tube OD 12 - 80mm, Max. 89mm,  and tube thickness 1 - 6.5mm.
 




























NOTES:

1.the tubes must be standard type, the deviation must be within machine tolerance.

2.A trained operator is necessary to make sure its normal work.

Structure
How to use:
  1. Polish the nozzle clean→Open uniform and symmetrical standard groove according to the relevant process→Make sure 1mm error measurement of pipe butt joint→Spot welding in advance.
  2. Program welding procedures on control panel→Fasten machine to tube-tube to be welded(locating hood)→Press start button on remote control→Fill the chamber of machine head with argon gas→Form a stable argon gas protection environment.
  3. A stable molten pool form is formed on workpeices→ Welding torch starts rotating→When workpieces rotates 365°, welder begins reduction process→ Current decreases gradually from welding current to crater arc current→Weld seams are connected→This procedure can be controlled by inputting fall time.
