Welding is an important tool for efficient maintenance of plants and quality fabrication in industry. The welding electrode or rod consists of a metal wire with a baked chemical/mineral coating. The coating of the electrode holds the key to quality welding.
Welding defects caused due to poor quality and weak welding are a nuisance because
The susceptibility to increased hydrogen from atmospheric exposure is a function of electrode manufacturer, packaging method, storage time and possibly diameter. Within manufacturers, the conditions that may influence the rate of moisture absorption include factors such as percent fill of electrode, tightness of joint, rolling vs. drawing, fluxing ingredients and lubricant types
Bry-Air Dehumidifiers: ensures longer shelf life of electrodes and eliminates welding defects.
Bry-Air Desiccant Dehumidifiers have effectively maintained the exact condition for welding electrode storage not only at L&T but also at Philips, Alsthom Power, Cochin Shipyard, Indian Oxygen, etc. A relative humidity of 40±5% RH at ambient temperature during manufacture, storage prior to packaging, packaging and bulk user storage is essential for retaining the quality of the mineral coating of the welding electrode. Bry-Air’s large range of standard and engineered Dehumidifiers ensure longer shelf life of electrodes.
