Overview
ABSTRACT
In this article, we explore the various factors affecting the quality of welded joints, from edge preparation to the management of thermal and metallurgical stresses. Critical issues such as cold cracking, hot cracking, lamellar tearing, and fatigue failures are discussed, along with practical recommendations to enhance weld durability.
Read this article from a comprehensive knowledge base, updated and supplemented with articles reviewed by scientific committees.

INTRODUCTION
Steel welding is a critical stage in many construction projects, both structurally and functionally. The quality of welded assemblies depends on a number of metallurgical, geometrical and procedural parameters. This article analyzes the main phenomena affecting weld performance, drawing on current practices and the precautions to be taken. Whether it's a question of edge preparation, consumable selection, hydrogen control or internal stress control, every aspect is essential to guarantee the reliability and durability of welded structures.
