Product Description of Girth Seam MIG Welding
For all arc welding processes,Girth Seam MIG Welding is important that the welding head be rigidly mounted over the part to be welded to obtain the highest quality weld results. Any vibration or instability of the weld head mounting will have an effect upon the arc length and produce inferior results. Welding manipulator is used when the weld head has to be moved to a position relative to the work piece. Welding manipulator provide the perfect solution as the boom can be lifted and lowered on the column and can be extended or retracted as required, The ends of boom are machined to carry a welding head.
we can provide some :Girth Seam MIG Mag Welding for Hydraulic Cylinder and Chemical Machinery
Girth Seam MIG Welding machine and welder composed of auto welding mechanical equipment. It can use with welding rotator, widely applied to industries such as boiler, pressure vessel, petroleum, chemical industry and mechanism.
+ Structure : stationary, stationary and revolve , moving and revolve type.
+ Cross section of boom and column are rectangular-section beams, with double-rail, welded into shape,stress-relieved and mechanical machined finely, ensuring higher precision;
+ Drooping of boom along horizontal travel is 2mm/m.
+ Boom lifting device including ratchet-type anti-dripping unit on the column, safe and reliable to prevent chains from incidental broken.
+ Guide roller is eccentric structure, decrease clearance between roller and rail surface, ensuring smooth and no shivering boom travel.
+ Column revolve unit has motor -driven and manual drive type.
+ Control box includes control box and pendant , interface with positioner and rotator also prepared
1.Vertical RingSeam Automatic Welding Machine
Girth Seam MIG Welding HF-400C is a productdesigned, manufactured and developed by our company. Used for circumferentialseam welding or 3D arc welding of water tank flange nuts, cylinder inlet andoutlet pipes, oil tank inlet and outlet, and hydraulic cylinder oil port.
Themachine rotates the welding gun 360 °, and the workpiece is at a standstill.Welding of circular seams (including intersection lines) where the entrance andexit and water tanks, hydraulic cylinders and other vertical intersections arerealized.

2. Introduction to Verticalring seam automatic welding machine
++ Weldable materials include: 45#, 27SiMn, 35#,20#, stainless steel, etc.;
++ Girth Seam MIG Welding is mainly driven by a stepper motor. The control system uses cnc controller and relay control as auxiliary to realize automatic control of welding. The weldingcurrent and voltage can be set directly on the operation panel. The machine hasreliable quality, beautiful appearance and high degree of automation.

++ The equipmenthas the functions of automatic lifting, automatic reset, automatic arcstriking,etc. It has a high degree of automation, a key operation, and stable and reliable operation. V-type thimble positioning mechanism is used forclamping to facilitate loading and unloading of workpieces.
++ For theintersecting line welds, Girth Seam MIG Welding is equipped with a mechanical copyingmechanism.When welding the inlet/outlet port on the cylinder body, it isnecessary to follow the contour height difference between the surface of the jointand the cylinder so as to weld the intersecting line curve. Welding cylinder interface, equipped with two lifting V-shaped frame for supporting the cylinderblock, under the V-frame roller, can be manually moved to facilitate the transposition.Under the fixture is equipped with an adjustable lifting platform.

3. Machine Brief
++ base and bed:
base for the weight of the whole machine.
++ Welding Drive Mechanism:
1) Automatic pneumatic lifting mechanism of the welding torch: Girth Seam MIG Welding is composed of a bottom plate, a guide rail and a lifting cylinder. It can be usedfor up and down movement of the welding torch and resetting of the weldingtorch; the gun speed can be adjusted by raising and lowering the cylinderadjusting valve; the rotating speed of the welding torch can be set by thespeed adjusting knob; the torch moves up and down, and the length of thewelding torch is adjusted by the manual screw positioning.
2) Turning gun mechanism: It consists of a rotating gun shaft and a geardrive mechanism. DC Stepper motor drive, this machine uses the workpiece does not move, welding torch rotation welding.
3) Up and down the gunfine-tuning mechanism (imitation mechanism): from the spring, the roller track up and down gun movement, with the gun movement to complete the welding torch's intersecting line track welding.
++ Girth Seam MIG Welding Pneumatic system:
Girth Seam MIG Welding device has an organichead cylinder. Supporting pneumatic components and solenoid valves areinstalled behind the equipment. When the equipment is working, make sure theair pressure is above 0.5Mpa.
++ Girth Seam MIG Welding electronic
1) Power Supply Part: Control Power Supply: SinglePhase AC220V 50/60HZ; Welder Power Supply:AC 3×380V 50/60HZ;
2) Control Box: The upper part of the controlbox is a button panel. All operations are performed on this panel. Electricalinstallation board: The electrical installation board is mainly composed of electrical components such as cnc welding controller , intermediate relay, and DC stepper motor driver. It connects and communicateswith the control buttonson the control panel through cables and wires to realize the control functionof the machine.
++ Welding Power Supply: Configured according tocustomer requirements. For details, please refer to the manual of the welding power source.
