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.
