What is required for proper welding on corner fittings to ensure strength?

Using low-hydrogen welding techniques is essential for maintaining the strength and integrity of corner fittings during the welding process. Low-hydrogen rods are specifically designed to minimize the introduction of hydrogen into the weld area. Hydrogen can lead to hydrogen embrittlement, a phenomenon that makes the metal more brittle and susceptible to cracking under stress. Employing these techniques ensures that the weld is strong and has a good impact resistance, which is critical for corner fittings that are subjected to various stresses during loading, transport, and handling of containers.

Additionally, low-hydrogen techniques typically involve controlling the welding environment and the moisture content of the materials used, contributing further to the overall quality and durability of the weld. This approach not only helps in achieving a stronger bond but also ensures that the corner fittings perform effectively throughout their service life, which is vital in the context of container stability and safety.
