Abstract
The paper gives the results of investigation of the influence of various kinds of alkali-silicate binder on adaptability to fabrication and welding properties of coated electrodes for tin bronze welding and surfacing. Both standard (sodium, potassium and mixed) and test lithium-containing liquid glasses were used during investigations. A procedure developed at PWI was used to determine plastic properties of electrode coating mixture and to assess the strength and hygroscopicity of electrode coatings. Studies of welding-technological and sanitary-hygienic properties of test electrodes were also performed. This resulted in selection of optimum kind of liquid glass, the most suitable for manufacture of coated electrodes for tin bronze welding and surfacing. 8 Ref., 4 Tables, 5 Figures.
