Piston rods for hydraulic cylinders
Cylinders for construction equipment, truck rollers, turbine rotors, rear axle shafts, inboard joints, surface rollers, copy rollers
Bonding of large-diameter, long parts is possible.
Parts are set quickly and with ease using rod and head (material) mounting device.
Quality can be controlled with a PC-based quality assurance device (condition management visualization, waveform display function).
Unmanned operation and automation are possible when used in conjunction with an auto loader.
Ideal, high-durability is obtained for “weld penetration” of bonded parts.
Thermal distortion is minimal, and high dimensional accuracy is obtained.
No spatter is produced, resulting in clean finishing.
The machine is equipped with a cutting device, eliminating the need for a deburring post-process.
Thermal distortion is minimal, eliminating the need for rod head correction.
Power consumption is 1/5 to 1/20 of that of other welding methods.
CO2 emissions can be reduced.
No toxic substances such as sparks or gas are produced.
We customize products in line with your company’s requests
