Quality welding is about more than just joining two pieces of metal. It's about understanding metallurgy, proper joint preparation, heat control, and the specific requirements of each application. Our welders bring this comprehensive knowledge to every job, whether it's a critical structural connection, a precision stainless steel assembly for a restaurant kitchen, or a decorative piece that requires beautiful, visible weld beads. At Iron Steel Laser Cut NYC, we take pride in welds that are both structurally sound and aesthetically clean.
Complete welding services using multiple processes to match every material and application requirement.
Metal Inert Gas welding is our most versatile and high-speed process. Ideal for carbon steel, stainless steel, and aluminum in a wide range of thicknesses. MIG welding delivers consistent, high-quality welds with excellent deposition rates, making it perfect for fabrication projects, structural work, and production welding.
Tungsten Inert Gas welding provides the highest precision and cleanest results of any welding process. Essential for thin materials, stainless steel, aluminum, and applications where weld appearance matters. TIG produces beautiful, precisely controlled welds with minimal distortion - the choice for food-grade, architectural, and visible weld applications.
Shielded Metal Arc Welding is the workhorse of structural and heavy-duty welding. Stick welding excels on thick materials, structural steel, and outdoor conditions where wind makes other processes difficult. Our welders are skilled in all common electrode types for structural, low-hydrogen, and specialty applications.
Flux-core welding combines the speed of MIG with the wind resistance of stick welding. Excellent for outdoor field welding, heavy plate fabrication, and high-deposition applications. Our flux-core welding is particularly effective for structural steel connections and heavy industrial repair work.

Fix broken welds, repair cracked metals, and restore weakened connections. We diagnose the cause of weld failures, properly prepare the joint, and re-weld using the appropriate process and technique to create a repair that's stronger than the original. Emergency repair service available for urgent situations.
Professional welding that starts with proper planning and ends with a quality inspection.
Every welding project begins with a thorough assessment. We evaluate the materials involved, joint configurations, load requirements, and environmental conditions. Based on this assessment, we select the optimal welding process, filler metal, and technique. For structural welding, we review the engineer's specifications for joint type, weld size, and quality requirements. For repair work, we diagnose the failure cause to ensure the repair addresses the root problem.
Proper joint preparation is crucial for weld quality. We clean all surfaces to remove rust, paint, oil, and contaminants that can cause weld defects. Joints are beveled, ground, or fitted as required by the weld specification. For critical welds, we ensure proper fit-up with controlled root gaps and alignment. This preparation step is often what separates a professional weld from an amateur one.
Our welders execute each weld with careful attention to heat input, travel speed, and technique. Proper heat management prevents distortion, maintains material properties, and produces consistent penetration throughout the joint. For multi-pass welds on thick materials, we control interpass temperature. For thin materials, we use techniques that minimize heat buildup and warping. The result is sound welds with full fusion and proper penetration.
After welding, every joint is visually inspected for proper profile, size, and surface quality. We check for undercut, porosity, cracking, and other discontinuities. Welds are ground smooth where specified, and any spatter is removed. For projects requiring additional inspection, we coordinate with third-party testing services for non-destructive examination (NDE) including ultrasonic, radiographic, or dye penetrant testing.

Common questions about our welding services in New York City.
MIG (Metal Inert Gas) welding uses a continuously fed wire electrode and is faster and more efficient for thicker materials and longer welds. It's the go-to process for structural steel, general fabrication, and production work. TIG (Tungsten Inert Gas) welding uses a non-consumable tungsten electrode with a separately fed filler rod, giving the welder precise control over heat and filler deposition. TIG produces cleaner, more aesthetic welds and is preferred for thin materials, stainless steel, aluminum, and applications where weld appearance is critical. We select the process that best matches your project's material, thickness, and quality requirements.
Yes, we weld aluminum regularly using both MIG and TIG processes. Aluminum welding requires different techniques and equipment than steel welding - specifically, AC TIG or pulse MIG capability, proper shielding gas (usually pure argon), and appropriate filler alloys (4043, 5356, etc.). Our welders are experienced with the unique challenges of aluminum including its high thermal conductivity, lower melting point, and oxide layer that must be cleaned before welding. We weld aluminum for architectural elements, equipment fabrication, marine components, and custom projects.
Absolutely. Our mobile welding service covers Manhattan, Brooklyn, Queens, the Bronx, and Staten Island, as well as Nassau and Suffolk counties on Long Island, Westchester, and northern New Jersey. Our on-site welding team arrives with truck-mounted welding equipment, portable generators, and all necessary safety equipment. We can perform MIG, stick, and flux-core welding on-site for repairs, installations, and field fabrication. Please call ahead so we can prepare the right equipment for your specific on-site welding needs.
When done properly, a welded joint can be as strong as or even stronger than the base metal. The key factors are proper joint design, correct filler metal selection, adequate penetration, and skilled execution. For structural applications, we use filler metals that match or exceed the base metal's strength (for example, E70 electrodes with 70,000 psi tensile strength for A36 steel with 58,000 psi tensile). The weld itself typically becomes the strongest part of the assembly. Problems arise only from poor technique, inadequate penetration, or contamination - issues our quality-focused process is designed to prevent.
Yes, cast iron welding repair is one of our specialized services. Cast iron requires special techniques because of its high carbon content, which makes it prone to cracking during and after welding. We use nickel-based filler rods specifically designed for cast iron, combined with careful preheating and slow cooling procedures to manage thermal stress. Our welders use a technique of short bead segments with peening between passes to relieve stress. While not every cast iron break can be perfectly repaired, we successfully restore most cast iron pieces including decorative elements, machinery components, and structural castings.
