Weld Head Locators
nnPowered Vertical LiftPrecision Boom Track All Arc Welding Processes Choice of Three Models
Optional Kingpin Base
Optional Travel Car
nnIntroduction
For all arc welding processes, it 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.The parts to be welded in the average work shop vary in size and shape. The welding point varies and it is therefore necessary to locate the welding head accordingly. The welding head locator pro-
vides a universal solution as the boom can be lifted and lowered on the mast and can be extended or retracted as required by the geometry and size of the part.Further capability is provided by the use of a kingpin base and a travel car, both of which extend the area in which the system can operate.Jetline weld head locators have been developed to be strong enough to carry a complete sub-
merged arc welding head with all the associated wire and fl ux handling equipment without droop or vibration. All Jetline weld head locators use case hardened tracks. Because of this, their movement is smooth and very precise, rendering them suitable for use with the gas tungsten arc welding (GTAW) process. They are even accurate enough for use with a micro-plasma welding head.All systems are supplied complete with powered lift which has variable speed control. The standard >
model can be used for vertical welding purposes if desired. Welding in the fl at position is achieved by the use of the optional power movement of the boom. >
nnDescription
The system consists of a crosshead which rides up and down a vertically orientated mast. The crosshead carries a boom which can extend out horizontally from the mast.The mast can be mounted to a fi xed base. The base can be fi tted with a kingpin to permit rotary swivelling of the mast. Either the fi xed or kingpin base can be mounted on a travel car to carry the weld head locator along a fl oor mounted track to various points along a large part. >
nnMastThe mast is mounted vertically on the base and consists of a heavy wall, rectangular box section tube with machined ways for the tracks. On the smallest model, the track is a case hardened vee-
way; on the larger models, the track consists of case hardened and ground roundways. The stress relieving and machining of the mast guarantees precision vertical movement of the crosshead on the mast. >
