Certified Stainless Steel Welding
Precision for Purity and Corrosion Control
RAW Welding Inc. delivers high-integrity stainless steel welding essential for hygienic environments, chemical resistance, and high structural applications. Our certified specialists serve food processing, refineries, chemical facilities, and industrial plants where system failure or contamination is not an option.
We ensure every weld maintains the alloy’s critical anti-corrosive properties and structural strength. This content is backed by the expertise of our founder, Ruben Espinosa, leveraging his over 30 years of industry experience.
The Challenge of Stainless Steel & Our Contamination-Free Solution
Welding stainless steel is complex; excessive heat can compromise its anti-corrosion properties and its oxide layer, leading to weld defects known as “sugaring.” We prevent this by combining specialized knowledge with advanced equipment. Our approach utilizes controlled heat input, specialized inert gas purging, and orbital welding where applicable.
This ensures full penetration and a non-porous, crevice-free finish on the inner diameter (ID), critical for sanitary compliance.
Our Meticulous Stainless Steel Welding Process
Purity is paramount in stainless steel fabrication. Our process begins with detailed cleaning and using dedicated tools to prevent cross-contamination from carbon steel. We apply precise TIG welding (GTAW) techniques and Argon back-purging to maintain the alloy’s corrosion resistance.
Following the weld, we offer post-weld treatments like passivation to restore the surface chromium oxide layer, maximizing the lifespan of your high-value assets.
Every weld undergoes rigorous quality assurance, ensuring compliance with industry codes such as AWS D1.6 for Structural Stainless Steel.

Frequently Asked Questions (FAQ)
Is your stainless steel welding process truly contamination-free for sanitary applications like food processing?
Yes, our process is designed to be contamination-free. We use dedicated cleaning protocols and tooling, along with Argon back-purging, to prevent cross-contamination from carbon steel and ensure a non-porous, crevice-free ID (Inner Diameter) weld surface, essential for meeting sanitary compliance standards.
We are concerned about "sugaring" (carbide precipitation) and maintaining the stainless steel's corrosion resistance. How do you prevent this?
We prevent “sugaring” by strictly controlling heat input and utilizing TIG/orbital welding techniques. This precise thermal control ensures the chromium oxide layer—which provides corrosion resistance—is maintained and not compromised during the welding process, maximizing the lifespan of alloys like 304 and 316.
Our industrial plant is located outside California. Can RAW Welding support major outages or emergency repairs nationwide?
Yes, we offer industrial services and 24/7 emergency response throughout the United States. Our capacity extends beyond California, supporting scheduled outages, turnarounds, and critical emergency repairs wherever your facility is located.
