About Nexa Weld & Flux LLP

Forging a Legacy of Metallurgical Excellence

Founded in 2017 and headquartered in Delhi, Nexa Weld and Flux LLP is a premier manufacturer of high-performance welding consumables. We specialize in producing an expansive, globally benchmarked range of products, including Mild Steel, Stainless Steel, Alloy Steel, Hard Facing, Maintenance, Low Heat, and Cutting/Gouging rods.

Our foundation is built on more than four decades of deep metallurgical expertise and a relentless commitment to quality. We don't just manufacture welding consumables; we engineer solutions that hold the world's most critical infrastructure together.

Our Story: A Heritage of Global Standards

NexaWeld represents the culmination of over 35 years of legacy in the welding industry. Our leadership team, spearheaded by industry veterans Mr. Sanjay Kapoor and Mr. Sunil Aggarwal, brings unparalleled technical and market insight to every product we develop.

This legacy of quality is rooted in our previous venture, MarutiWeld, founded by Mr. Kapoor. MarutiWeld's reputation for uncompromising quality culminated in its 2013 acquisition by the German conglomerate Boehler Voestalpine, the second-largest welding company globally. In a powerful testament to our exacting manufacturing standards, Boehler Voestalpine retained our proprietary formulations and processes exactly as they were post-takeover.

Combined with Mr. Aggarwal’s decades of experience as the industry's leading marketing stalwart and top distributor, NexaWeld operates with a profound understanding of what structural fabricators and heavy industries demand from their consumables.

State-of-the-Art Manufacturing Capabilities

To deliver on our promise of exceptional quality, NexaWeld operates advanced, multi-line manufacturing facilities with dedicated capacities of 300 MT for welding electrodes and 100 MT for Flux Cored Wires (FCW) per month.

Our infrastructure is designed to control every variable of the production process:
