UTP 8 electrode, analog of OZCh-4 for cold welding and a naplavka of cast iron

UTP 8 electrodes (analog of electrodes of OZCh-4) — it is low - a hydrogen electrode for cold welding of cast iron: gray, malleable, high-strength and cast staly, for welding of cast iron from a stalyama, copper and copper alloys. It is especially recommended for single-pass welding and drawing the first layer on cast iron at multilayered welding. Allows to weld old and greasy cast iron at restoration and repair.

The electrode of UTP 8 has excellent welding characteristics. The high-quality covering allows to carry out welding without spraying and to control a welding bathtub. The welding seam and near a sutural zone have high plasticity and can be processed by a file. When processing by the metal-cutting tool on border cast iron - the built-up metal is not formed "step".
The electrode of UTP 8 possesses a stable arch and provides the flat structure of a seam excluding undercuts. It is especially good at the combined welding about iron the nickel electrode of UTP 86 FN used as filling at multilayered welding.

Universal application. Welding on a direct current of direct polarity (-) on an electrode.

The zone of welding has to be previously rather widely cleared, an electrode to hold a vertical - but, to keep a short arch. Thickness of the roller is no more than 2 diameters of the core. Roller length for one pass no more than 10 diameters of an electrode. To delete slag right after drawing the roller and to make pro-forging. To maintain intermediate temperature not above 80ºС.

To make renewal of an arch on a welded seam, but not on the main metal.
