摘要

摘要本文的目的是验证在焊接接头区域进行多点温度测量的方法,作为对有关接头进行质量评估的工具。为了建立给定点的温度读数、热输入值和点与焊接轴的距离之间的关系,对一组填充焊缝进行了初步试验。计量资料的相关分析显示0.99的高水平。在研究的第二阶段,测量了两种不同焊接方法的焊接接头的温度:HPAW(混合等离子弧焊)和SAW(埋弧焊)方法。所得的温度曲线反映了给定焊接过程中热输入的强度。当与金相试样的热效应相比较时,曲线的形状显示了生产条件下接头质量评估的潜力。对于先进的大功率焊接工艺,用经典的分析方法估计热效应是不精确的。监测温度可以在焊接过程中评估接头的质量,这可能是限制由MART钢(高级高强度马氏体钢)制成的接头的HAZ(热影响区)回火的一个显着因素,这种现象极大地降低了接头的强度。本文提出的焊接接头质量评价方法可以扩展焊接热条件的分析。

Welding Thermal Cycles of Joints Made of S1100QL Steel by Saw and Hybrid Plasma-Mag Processes
Abstract The aim of this article is to validate the method of conducting a multipoint temperature measurement in the area of welded joints as a tool for quality assessment of the joints in question. In order to establish a relationship between temperature readout at a given point, the value of heat input and the distance of the point form the weld axis, preliminary tests have been conducted on a set of padding welds. Correlation of measurement data analysis showed the high 0.99 level. In the second stage of the study, temperatures of joints welded with two different methods have been measured: the HPAW (Hybrid Plasma – Arc Welding) and classic SAW (Submerged Arc Welding) method. The obtained temperature curves reflect the intensity of heat input in a given welding process. When compared to thermal effects on metallographic specimens, the shapes of the curves show a potential for quality assessment of joints in production conditions. Estimating thermal effects with classic analytical methods proves imprecise with respect to advanced high-power welding processes. Monitoring temperature will allow to assess the quality of joints in the course of welding, which may be a remarkable factor in terms of limiting the HAZ (heat affected zone) tempering of joints made from MART steels (advanced high strength martensitic steel) – a phenomenon that exceedingly decreases the strength of the joints. The method for quality assessment of welded joints presented in this paper allows to extend the analysis of welding thermal conditions.
