- Authorized BIS certifies that electrode welding stainless steel core wire is in conformity with the standard IS 10631:1983.
- Such a certificate coupled with a quality product is a winning combination which industrial clients and government tenders cannot resist.
- It is an effective means of quality assurance and alloy composition can also be monitored through it during manufacturing.
- Greatly simplifies the process of getting the green light for both local and foreign purchases.
- Increases the value of the brand and creates a positive cycle whereby business keeps expanding.
Introduction
A mid-sized stainless steel welding electrode manufacturer in Pune was struggling to win orders from large industrial clients. Even though the company was making high-quality electrodes, the procurement teams were repeatedly requesting proof that the products complied with Indian standards. Obtaining BIS certification for a stainless steel welding electrode core wire according to IS 10631:1983 completely changed the situation. It was the factor that really helped the company to gain trust, increase the client base, and get both domestic and export contracts, as it gave an unequivocal quality, chemical composition, and mechanical properties assurance.

What is IS 10631:1983?
IS 10631:1983 is an Indian standard that defines the necessary requirements of stainless steel electrode welding core wires. It specifies the chemical composition, the mechanical properties, and the manufacturing processes that are required to keep the product quality stable and its performance reliable in the welding applications.
The standard is critical for manufacturers because it ensures:
- Chemical Composition Compliance: The standard details the permissible levels of chromium, nickel, and other alloying elements, which are necessary to make the material resistant to corrosion and durable.
- Mechanical Properties: It specifies tensile strength, elongation, and other major parameters to make sure that the electrode is capable of functioning during the welding process.
- Manufacturing Guidelines: It employs the manufacturing methods of the core wire, dimensional tolerances, and quality control aspects to maintain the consistency of the product throughout the different batches. ISI MARK
- Testing Methods: There are standard procedures detailed in the document, which are used to determine the ease of welding, the amount of slag formed, and the quality of the deposition, which in turn confirm the performance of the batch tested.
Why is BIS Certification Mandatory
- It makes the product comply with the Indian standards regulations and thus, legal problems are avoided.
- Provides the company with the industrial and government procurement business opportunities.
- Assures that quality, chemical composition, and weld performance are maintained at the same level.
- Helps in gaining customer trust and confidence with the ISI mark.
- Helps in risk reduction of operational failures, safety hazards, and money losses.
