FIG. 1 is a circuit diagram of a welding power source FIGS. 2a-2d show some voltage and current curves FIG. 3 shows, somewhat schematically, an welding inductor. FIGS. 4, 5 and 6 are different modifications of the circuit diagram of FIG. 1. DESCRIPTION OF A PREFERRED EMBODIMENT A...
FIG. 5 is a schematic diagram showing a pneumatic and electrical system of the type used to control the operation of the welder. Referring in detail to the drawings, a flash-butt welding machine is shown generally at 6. The machine is of generally rectangular shape and includes a base plate...
The standards and regulations that apply to construction technology, boiler, machine, reactor and shipbuilding in regard to mechanical properties, chemical composition and suitability of the materials for welding must be observed. 1.4.1 Combinations for the drawn arc process Generally, for the drawn ...
If a problem cannot be corrected by following the instructions, take the machine-to the nearest Red-D-Arc Location. TROUBLE 1. Machine fails to hold the "heat" constantly. CAUSES A. Rough or dirty commutator. B. Brushes may be worn down to limit. C. Field circuit may have variable ...
The starting sequence is as described in the "hot starting" procedure except that when the arc strikes, the machine welds at the current* and voltage set by the start controls panel until the time set on the "Time in Seconds" control elapses. The circuit then automatically switches to the...

The joints produced at the MPW setup were tested for their bond strength by tensile shear testing in a Z100 testing machine (by Zwick, Ulm, Germany) with three repetitions for each parameter set at a testing velocity of 10 mm/min. Additionally, for one joint of each series, a cross-sect...
