The Influence of Resistance Spot Welding on Weld Joint Quality and Service Life of Electrodes

Popis výsledku v původním jazyce

The contribution deals with results of research of resistance spot welding of deep drawn sheets with surface treatment used in automotive industry. Welded material was low carbon, high strength, deep drawn steel HX180BD with hot-dip galvanic layer ZnMg.There were welded two of the same plates with thickness 0.8 mm with the same surface treatment. To obtain welding parameters area there was made optimalization according to EN ISO 14327. The weld joint quality was evaluated by visual testing and mechanized peel test according to EN ISO 14270. Spot joints welded by optimized parameters were compared with joints welded by parameters commonly used in automotive industry for this material. There were made durability tests of electrodes (according to EN ISO8166) for optimized welding parameters and commonly used parameters. The comparison of worn electrodes shown, that the optimized parameters result in increased service life, but also to reducing the strength of resistance spot weld joints
