Dataset of Reinforcement and Width Estimation in GMAW Weld Bead Process

In the first CSV file, named 'data.csv', the first columns describe the timestamp of the acquisition in hour:minute:second miliseconds format starting from the hour the experiment was registered, a Boolean flag for when Arc is open or closed, the position of the torch in mm, its speed in mm/s, voltage in Volts, current in Amperes, and wire-feed speed in m/min. The follow columns are the pixels of the thermographic image, with each row corresponding to a different measurement and a different image. This way, each column starting from "1x1" column represents the XY axes pixel values. The second CSV file, named 'scan.csv', contains 181 columns. The first 2 columns are related to the values of calibration of height and width of each pixel in the image. The follow three columns are the position of the sample, the width and the reinforcement. The remaining rows contain the measured pixels from the laser beam line. Each row corresponds to a different measurement and a different position of scanning. The data.cnf file contains essential information about the test parameters under which the data, later recorded in data.csv, was collected. Meanwhile, the data.stm file stores the sequence of stimuli transmitted to the welding source during the experiment. In this file, it is possible to see four lines of information regarding the steps of the experiment. The first number in each line is the step identification, followed by Welding Speed(mm/s), Welding Voltage(V), Wire feed speed (m/min) and Arc status (boolean). Both of these files are used in the Thermo Data Welding software. The met-data.dat file has the data regarding the profile of penetration as seen in a macrograpric analysis. It is composed by two rows: The first one is related to the data processing configuration values such as height in the left side (mm), height in the right side (mm), total length of the part (mm), pixels for the gausian filter, pixel thresholds and pixel cleaning kernel. The following row has the data for the penetration profile itself in an array.第一个CSV文件名为"data.csv"，其首列记录以实验启动时刻为计时起点、采用小时:分钟:秒.毫秒格式的采集时间戳；后续列依次为电弧(Arc)通断布尔标记、焊枪位置（单位：mm）、焊枪移动速度（单位：mm/s）、电压（单位：V）、电流（单位：A）以及送丝速度（wire-feed speed）（单位：m/min）。文件中后续列均为热成像图像（thermographic image）的像素值，每一行对应一组独立的测量数据与一张不同的热成像图像。其中，从"1x1"列开始的每一列，分别代表XY坐标系下的像素灰度值。 第二个CSV文件名为"scan.csv"，共包含181列。前两列用于校准图像中每个像素的高度与宽度参数；接下来三列分别为试样位置、焊缝宽度与余高；剩余列均为激光束线（laser beam line）的实测像素值。每一行对应一组独立的测量数据与一个不同的扫描位置。 "data.cnf"文件存储了后续在"data.csv"中记录的数据集所对应的测试参数关键信息。"data.stm"文件则保存了实验过程中向焊接电源发送的激励序列，该文件包含四行实验步骤相关信息：每行的首个数值为步骤标识，后续依次为焊接速度（mm/s）、焊接电压（V）、送丝速度（m/min）与电弧通断状态（布尔值）。上述两类文件均可在Thermo Data Welding热成像焊接软件中使用。 "met-data.dat"文件包含宏观金相分析（macrographic analysis）所得的熔深轮廓（penetration profile）相关数据，该文件由两行组成：第一行为数据处理配置参数，包括左侧高度（mm）、右侧高度（mm）、工件总长度（mm）、高斯滤波（Gaussian filter）所用像素数、像素阈值以及像素清理卷积核参数；第二行为熔深轮廓本身的数组数据。
