Descriptions
The weld is a cast metal structure, and its chemical and mechanical properties are determined by the filler metal used to create it. While base metal quality is often rigorously controlled, the quality of welding consumables—sticks (SMAW electrodes), wires (GMAW, FCAW, GTAW), and fluxes (SAW)—can be a variable that is taken for granted. Relying solely on the manufacturer’s Certificate of Conformance (C of C) is a risk. Lot-to-lot variations, improper storage leading to moisture pickup, or even mislabeling can introduce a consumable that does not perform as expected, leading to weld defects, failed mechanical tests, or poor performance in service.
NY Welding LLC provides an independent, third-party verification service for your weld consumables. Our testing goes beyond the paperwork to analyze the actual chemistry and performance of the material you are putting into your welds.

The Invisible Threat in Your Weld. Quantify and Control Diffusible Hydrogen to Eliminate Cold Cracking.
Hydrogen-Induced Cracking (HIC), often called “cold cracking” or “delayed cracking,” is a metallurgical time bomb. It can occur hours or even days after a weld has cooled and passed visual inspection, leading to sudden, brittle fractures that can have devastating consequences. The primary agent of this failure is diffusible hydrogen—atomic hydrogen that dissolves in the molten weld metal during the welding process. As the weld cools, this hydrogen becomes trapped and can accumulate at microstructural discontinuities (like grain boundaries or non-metallic inclusions) and areas of high tensile stress (such as the heat-affected zone). When a critical concentration is reached, the pressure from the recombined molecular hydrogen can initiate a crack.
The single biggest source. This can come from hydrated oxides (rust) on the base metal, moisture in electrode flux coatings, damp submerged arc fluxes, or humidity in the shielding gas.
Oils, greases, and paints on the plate surface can break down in the arc, releasing hydrogen.
Water vapor in the surrounding air can be dissociated in the arc if shielding is inadequate.
If HIC occurs in production, diffusible hydrogen testing of the consumables used is one of the first and most important forensic steps in a root cause analysis.
