Abstract

This paper first proposes to define the welding parameters of the GTAW (TIG/WIG) heat exchanger for a robotic system. The paper describes the first process of welding performed on the heat exchanger assembly, named pilot. An analysis will go through all the stages starting with the programming and simulating description of the welding process (cold tests), up to the analysis of the test results obtained after the pilot welding. The paper shows the programming technique used for the robotic welding process of the heat exchanger, more specifically, the article makes an explicit interpretation of the programmed code into the robotic system console. The documentation describes the existing sequences from the two programs developed in the console of the robotic system for the welding of the 288 pipes found as components of the heat exchanger assembly.
