German UTP electrode parameters:
UTP electrode welding current range – 90-110A; Packaging and packaging – 4 packs of 5,6 kg in cardboard boxes (22,4 kg); Diameter – 4,0 mm; Length – 400 mm; Welding current range – 100-130A; Packaging and packaging — 4 packs of 5,2 kg in a cardboard box (20,8 kg); Welding process: When welding on direct current or alternating current, electrodes of UTP 86 FN are more preferred. When welding on direct current with direct polarity, the preferred depth provarivaniye when welding fillet joints. Welding, under various space regulations, is best performed on AC. The welding area must be cleaned extensively beforehand to keep the electrode vertical, maintain a short arc, and enable fast welding speeds.
German UTP electrode advantages:
UTP electrodes have the unique welding characteristics of medium welding, have a stable arch shape, and provide a flat structure of the weld that does not include undercuts. It is particularly good at producing corner joints when a smooth joint surface needs to be provided, for example when welding cast iron (GGG) flanges or their connection to cast iron (GGG) pipes. The covered bimetallic core provides high tokoprovodnost and unique productivity. Accumulated metal treshchinostoyek easily succumbs to processing. Chemical composition of combined metals, %: nickel (Ni) — base, iron (Fe) — 45%, Углерод© — 1,2%. Mechanical properties of joint metal: Gap temporary resistance: Gv>=500 MPas; Relative elongation: >=18%; Flow limit: Gt>=340 MPas; Hardness: 220 HB. Dimensions, welding current: diameter - 2,5mm; length - 300mm; welding current range - 65-90A;
