BIS CERTIFICATION OF COVERED ELECTRODES FOR MANUAL METAL ARC WELDING OF CARBON AND CARBON MANGANESE STEEL

INTRODUCTION

Welding plays a crucial role in various industries, serving as the backbone of construction, manufacturing, automotive, aerospace, and many other sectors. It is a fundamental process for joining metals, enabling the fabrication of structures, machinery, and components essential for modern society. From towering skyscrapers to intricate machinery and pipelines spanning vast distances, welded joints are the invisible bonds that hold our world together. In the realm of welding, adherence to standards is paramount to ensure the safety, reliability, and quality of welded structures and components. One such standard that governs the production and use of welding consumables, particularly covered electrodes for manual metal arc welding, is the Indian Standard IS 814:2004.

IS 814:2004 COVERED ELECTRODES FOR MANUAL METAL ARC WELDING OF CARBON AND CARBON MANGANESE STEEL

IS 814:2004 is an Indian Standard established by the Bureau of Indian Standards (BIS) that outlines the requirements for covered electrodes used in manual metal arc welding processes involving carbon and carbon manganese steel. This standard plays a critical role in regulating the quality and performance of welding consumables, ensuring the integrity and reliability of welded joints across various industries. Key elements involved are as under :Scope: IS 814:2004 defines the scope of covered electrodes for manual metal arc welding, specifying the types of steel covered (carbon and carbon manganese steel) and the intended applications. Tensile Strength: The standard sets maximum limits for the tensile strength of the weld metal deposited by the electrodes, ensuring that it does not exceed 610 MPa.

Hydrogen Control: Certain electrodes are designed to control hydrogen levels in the weld metal, mitigating the risk of hydrogen-induced cracking.

Classification System: Electrodes are classified based on their properties and characteristics using a coding system, facilitating the selection of suitable electrodes for specific welding applications.

Type of Covering: Various types of electrode coverings, such as acid, basic, rutile, and semi-basic, are defined, each offering unique performance attributes.

Welding Positions: Electrodes are specified for use in various welding positions, including flat, vertical, horizontal, and overhead positions, ensuring versatility and adaptability in welding operations.

Current Conditions: Electrodes are designed to operate under specific welding current and voltage conditions, optimizing performance and efficiency during welding processes. 

IS 6419 WELDING RODS AND BARE ELECTRODES FOR GAS SHIELDED ARC WELDING OF STRUCTURAL STEEL  

This standard prescribes of solid filler rods and wires for welding structural steel by inert gas tungsten arc welding (TIG), gas metal arc welding (MIG) or CO2 welding process. The chemical composition and tensile properties of filler rods and wires are also specified. This standard also prescribes mechanical properties of melt deposits. Rods supplied in straight lengths shall preferably have lengths 250, 350, 450, 500, 600, 750, 900 , 1000 mm. The temper of the filler metals shall be such that they are suitable for uninterrupted feeding on automatic or semi-automatic welding equipment. The cast of filler metals shall be such as to have imparted a curvature to the filler metal so that a specimen sufficient in length to found one loop or a maximum 3 m when cut from the package. Soundness test, all weld metal mechanical test, all weld impact test are some of the tests specified for wires and rods. 

QUALITY CONTROL ORDER (TECHNICAL REGULATION) ISSUED BY THE DEPARTMENT FOR PROMOTION OF INDUSTRY AND INTERNAL TRADE, MINISTRY OF COMMERCE AND INDUSTRY, GOVT. OF INDIA ON 09 AUGUST 2023 FOR MANDATORY BIS CERTIFICATION

The DPIIT, Ministry of Commerce & Industry, Govt. of India, has issued an order, making it mandatory for electrodes to be used in India, whether manufactured in India or imported from foreign countries, shall mandatorily carry the Standard Mark (ISI Mark) of the Bureau of Indian Standards under a valid BIS license. In short, it has become obligatory for all the manufacturers of aluminium cans, whether in India or overseas, to immediately apply for BIS license and obtain a valid BIS certification license for electrodes.

BIS CERTIFICATION SCHEME AT A GLANCE
