Elaboração de especificação de procedimento de soldagem pré-qualificada: soldagem de junta de topo em sistema de ancoragem de uma linha de vida rígida horizontal

Abstract

The present work presents the elaboration of a pre-qualified welding procedure specification for the GMAW (Gas Metal Arc Welding) process, through a bibliographical review of Brazilian and foreign standards, aiming to define the parameters to be applied to the butt joints. that connect “I” profile beams. The structure used as a reference to determine the dimensions of the material to be welded and the environmental conditions of welding, consists of a horizontal rigid lifeline anchoring system, installed in a closed environment, a seed pod storage shed. Welding is a fundamental process for the structural integrity of anchoring systems, ensuring the safety of workers using the lifeline. GMAW welding was chosen due to its efficiency and versatility. The study will address the selection of welding parameters, the preparation of the joints, the materials to be used and the criteria that allow this specification to be classified as “pre-qualified” according to the standard; aiming to ensure the quality and reliability of the weld. Through this work, it is expected to contribute to the standardization and improvement of welding procedures in anchoring systems, aiming at the safety and efficiency of structures.
