What is Cap Pass in Welding? Welding, at its core, involves joining two or more pieces of metal to create a solid and durable structure. However, achieving this outcome requires more than just running a bead of molten metal along the joint. Different stages, or passes, contribute to the quality …

How to measure Fillet Weld Size Welding is an essential process in many industries, and fillet welds are one of the most common types of welds used to join metal parts. However, the quality of a fillet weld largely depends on its size, which directly affects its strength and functionality. …

ASME B31.4 vs ASME B31.8 Pipelines are the backbone of global transportation for fluids and gases, enabling the efficient movement of essential resources over vast distances. The ASME (American Society of Mechanical Engineers) has developed a series of standards that ensure the safety, efficiency, and reliability of these pipelines. Among …

Differences Between Water-tube and Fire-tube Boilers Introduction Boilers are central to energy generation and industrial heating processes, and understanding their design is critical for optimal performance. For a boiler engineer, the distinctions between water-tube and fire-tube boilers go beyond basic operation—they influence efficiency, safety, and application suitability. Let’s explore their …

Introduction to Low Hydrogen Welding Electrodes What Are Low Hydrogen Electrodes? Low hydrogen welding electrodes, often abbreviated as “low-hy electrodes,” are consumables designed to minimize the hydrogen content introduced during the welding process. Hydrogen can enter the weld pool from moisture, contaminants, or electrode coatings. This hydrogen can cause delayed …

Cold Cracking: Causes and Cures Introduction Welding is more than just joining metals—it’s about creating structures that can endure stress and last a long time. However, welding comes with challenges, and one of the most critical is cold cracking. Known as the “silent destroyer” of welds, cold cracking can occur …

Weld Acceptance Criteria ASME B31.3 Process Piping Weld quality is essential in industries where process piping transports chemicals, gases, and liquids. The ASME B31.3 standard for process piping sets stringent guidelines to ensure safe and reliable welds. One key component of this standard is the weld acceptance criteria, which provides …

On-Torch Extraction of Welding Fumes Introduction to Welding Fumes and Safety Concerns Welding is critical to various industries, from automotive manufacturing to construction and shipbuilding. However, welding processes release hazardous fumes that pose significant health and safety risks. Managing these fumes effectively is crucial for maintaining a safe work environment, …

The Primary Welding Positions: Flat, Horizontal, Vertical, and Overhead Introduction to Welding Positions The Primary Welding positions are foundational concepts in welding, as they define the orientation of the workpiece and the welder. This positioning not only affects the welder’s approach to the task but also influences the quality, strength, …
