Hydrogen may be the smallest atom, but in welding it creates serious problems. During welding, hydrogen enters molten metal from moisture, flux, or electrodes. As the weld cools, hydrogen becomes trapped inside the crystal structure and builds internal pressure. This makes the metal brittle and leads to delayed cracking, especially in the heat affected zone. This failure is known as hydrogen induced cracking or hydrogen embrittlement. Using low hydrogen electrodes, proper preheating, and dry ele

Most weld failures don’t occur in the weld metal—they occur in the Heat Affected Zone (HAZ). Visit weldfabworld.com Follow Technical Master HAZ is the area of base metal that is not melted but undergoes metallurgical changes due to welding heat. Grain growth, increased hardness, and reduced toughness can make this zone critical. Proper control of heat input, correct welding parameters, and post-weld heat treatment are essential to maintain weld integrity. Understanding HAZ helps welders, enginee

Heat input plays a crucial role in welding quality and performance. Too much heat input can cause excessive distortion, grain growth, and reduced toughness, while too little heat input may lead to lack of fusion and weak joints. By properly controlling voltage, current, and travel speed, welders can achieve strong, reliable, and defect-free welds. This concept is extremely important in pipelines, pressure vessels, and structural fabrication where safety and durability matter the most. Understand
