WHL Weld Head Locator / Manipulators

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. > 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. > The 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. >

Jetline weld head locators are designed to use either an Acme style leadscrew or a ballscrew for elevation of the crosshead and boom. > The boom provides horizontal movement in and out from the mast. It is made of rectangular box section tubing and, after stress-relieving, is ma- chined to accommodate hardened ways identi- cal to those used on the mast. The boom rides on hardened guide wheels with sealed bearings.Machined mounting plates located at each end of the boom are used for the mounting of the weld- ing head. Welding equipment can be mounted on both ends providing that the total...

This type of car is used in conjunction with the larg-er sizes of weld head locators. It consists of a large platform on which the weld head locator, with or without the kingpin, is mounted. Provision is made on the platform to locate the welding equipment and other ancillary equipment such as fl ux recov- ery or wire pay-off packs. The platform is large and robust enough to carry the operator control station. This permits the operator to travel on the car along with the equuipment as the weld takes place.The fl oor mounted track comprises rail sections which are welded to cross members to...
