Welding, automatic machine

Teams of welders join the pipe sections into a continuous tube. The most modern welding techniques involve automatic welding machines. X-ray equipment is used to inspect welds, When several sections of pipe have...

The component parts are heated. The blade shape is laid out on the hub disc and tack welded, which ensures that the blade cannot be misaligned. The hub disc with the tack welded blades are placed on the automatic impeller welding machine and heated for welding. After the blades are completely welded to the hub disc, the cover disc is welded on by the same means. The completely welded impeller is then ready for annealing and finish machining.

Mechanical scenarios are mai r. They include metal presses, buzzers for dressing or planing timber, lathes and drill presses. Automatic or semi-automatic systems include contact or spot-welding machines on vehicle production lines, either controlled by an operator or fully robotic, automatic control of chemical process facihties such as oil refining (with a manual override), car cruise control and aircraft autopilots. Mechanical systems place large amounts of energy at the operator s disposal so a high-powered car and an inexperienced driver can be a fatal combination. 

Cast-on battery elements are either continuously connected or made in discrete one-cell modules. The first method requires that long intercell connections be used, which travel over the intercell partition and are seated in a slot in this partition this is known as the loop-over-partition design. In the second cast-on method, tabs on the ends of the plate straps are positioned over holes that have been prepunched into the intercell partitions of a battery case. These tabs are welded together manually with a very small torch or automatically by a resistance welding machine. The latter also squeezes the tabs and the intercell partition to provide a leak-proof seal. 

Alternatively, soldered-cored wire (where the solder alloy is of the required karatage) is used to make the chain, which is also postsoldered in a belt furnace. On more modem machines, instead of postsoldering, the solid wire links are automatically welded by laser or microplasma welding torch in situ on the machine [35].
