摘要

本文是利用冷金属转移(CMT)机器人金属活性气体(MAG)焊接技术对乘用车后座靠背角焊缝质量进行评价研究的结果。当机器人化的过程中，参数，如过程本身的速度，精度和焊接接头的质量是重要的。试验材料为双相铁素体-马氏体钢HCX 590X，对4个焊缝节点进行了评价。采用目测法和毛细管法对焊接接头质量进行了评价。在金相分析的基础上，对焊缝根部的焊缝深度进行了评价。测量值随后用统计学方法方差分析(ANOVA)进行处理。研究证实，焊缝的最终质量取决于焊缝根部焊缝进入基材(BM)的深度。该参数对焊缝的影响最大，并导致整个产品停止使用。

EVALUATION OF FILLET WELDS PROPERTIES PERFORMED BY COLD METAL TRANSFER ROBOTIC METAL ACTIVE GAS WELDING TECHNOLOGY

The article is the result of research evaluating the quality of fillet welds used in the production of rear seat backrests for passenger cars and manufactured robotically by Cold Metal Transfer (CMT) robotic Metal Active Gas (MAG) welding. When robotizing the process, parameters such as the speed of the process itself, accuracy and quality of the welded joints are important. Dual-phase ferritic-martensitic steel HCX 590X was used for the experiment and four weld nodes were evaluated. The quality of welded joints was evaluated by visual and capillary methods. Based on the metallographic analysis, the weld depth of the weld root was evaluated. The measured values were subsequently processed by statistical method ANalysis Of Variance (ANOVA). The research confirmed that the final quality of the welds depends on the depth of the weld root weld into the Base Material (BM). This parameter has the greatest effect on the welds made and results in the entire product being taken out of service.

期刊介绍： At present, transport is one of the key branches playing a crucial role in the development of economy. Reliable and properly organized transport services are required for a professional performance of industry, construction and agriculture. The public mood and efficiency of work also largely depend on the valuable functions of a carefully chosen transport system. A steady increase in transportation is accompanied by growing demands for a higher quality of transport services and optimum efficiency of transport performance. Currently, joint efforts taken by the transport experts and governing institutions of the country are required to develop and enhance the performance of the national transport system conducting theoretical and empirical research. TRANSPORT is an international peer-reviewed journal covering main aspects of transport and providing a source of information for the engineer and the applied scientist. The journal TRANSPORT publishes articles in the fields of: transport policy; fundamentals of the transport system; technology for carrying passengers and freight using road, railway, inland waterways, sea and air transport; technology for multimodal transportation and logistics; loading technology; roads, railways; airports, ports, transport terminals; traffic safety and environment protection; design, manufacture and exploitation of motor vehicles; pipeline transport; transport energetics; fuels, lubricants and maintenance materials; teamwork of customs and transport; transport information technologies; transport economics and management; transport standards; transport educology and history, etc.
