It is carried out the determination of consumption parameter of coated tubular electrodes for hardfacing of pieces in sugar industry. Two versions of coated tubular electrodes (ferroalloy particle size in the soul =0,1 mm and in the range of 0,1- 0,25 mm) are evalueted. This study is made in comparative way, using the DIN E60-10 Z commercial coated electrode, which has same diameter (4mm) and same application (hardfacing, widely applied in sugar industry) as this studied. Starting from the results, the best operational range for this electrode is established, in that referred to welding current, looking for the biggest efficiency in the application.

The feasibility study is very important for the decision making in a project appraisal. The paper work "Feasibility economical and financial analysis for a Flux production using in a sugar cane industry" is made according to the development project for welding materials in The Center of Welding Research of the university la Universidad Central "Marta Abreu" de Las Villas, it focus on carry out a economical-financial feasibility study for Manganese Bonded Flux. This study explains the necessary elements to make a right decision about the flux investment in the national market area showing possible advantages for the national development.

In this work is carried out the evaluation of hardfacing welds obtained by shielded metal arc welding process (SMAW) using the CIS1 experimental tubular electrodes, for the recovery or production of sugar cane knives. The welds are studied from the metallographical point of view, analyzing the effect of the piece geometry in the microstructural characteristic, in the dilution coefficient and consequently in their abrasive wear resistance.

The use of slag of iron production is presented in cupola furnace ovens in sugar industry companies for the obtaining of a matrix of a flux for recovery of pieces by submerged arch in this sector. From the analysis of the characteristics of the slag generated in the mentioned foundries their processing outline is conceived for the adaptation to the characteristics of the matrix of a flux agglomerate for the recovery of pieces that responds to a wide demand range, contributing to an increase in the durability of machine elements and to the decrease of the slag like residual solids.

A coated tubular electrode for hardfacing of pieces which work under abrasive wear conditions in the sugar industry is obtained. The above-mentioned is carried out by the addition in the electrode core of a ferroalloy in powder form, using simultaneously a forming process with butt closing. The obtained tubular wire, in reel form, with diameter 4 mm, is fractioned to longitude of 350 mm and recovered by immersion with a basic type coating. Using the obtained electrode his potential application is studied by the evaluation of multi-layer weld and the basic criterion about their possible use under abrasive wear condition were established.

The present work approaches the obtaining of manganese flux to be used in Submerged Arc Welding (SAW). This study starts with a transformation of a manganese mineral by the increase of temperature and the addition of other minerals. These conditions modify the binary system MnO-SiO2 and the behavior of the flux. A comparative analysis of the technological behavior of the flux during the welding process as well as the chemical and mechanical properties of the junctures in relation with trademark fluxes are presented.

The present paper studies the characterization of a low carbon steel to be use in the manufacturing of the splints of cane transporters. It was made the chemical characterization by Emission Atomic Spectroscopy (EEA) and classical Chemical Analysis, as well as the micro structural characterization by metallographic analysis, measurement of grains sizes and micro and macrohardness. It was made a search of homologous samples, from the obtained results and its essential properties, using for it different selection criteria and tools of searches, for instance: International Handbooks, Standards and data bases.
