Former Welding Warehouse Inc Customer? We’ve Got You Covered.

The Welding Warehouse, Inc. — formerly located at 7654 E. Slauson Ave, Commerce, CA 90040 and reached at 1-800-800-1150 — built a strong reputation as a welding wire and filler metal distributor serving aerospace, defense, industrial, and specialty fabrication industries across the United States.

Their closure leaves a gap in the market for specification-grade filler metals that thousands of engineers, procurement teams, and welding operations depend on. WeldTool Technologies steps in as the natural, superior replacement.

We’ve built our business on exactly the same product categories The Welding Warehouse carried — AMS, AWS, MIL, nickel alloys, titanium, stainless steel, cobalt, aluminum, magnesium, copper, brazing alloys, flux cored wire, and mild steel — with a broader selection, deeper stock, and infrastructure built to fulfill orders at scale.

The Same Alloys. A Better Partner.

Whether you were ordering exotic nickel alloys for high-temperature turbine repair, titanium TIG wire for aerospace fabrication, or stainless steel flux cored wire for pressure vessel work — WeldTool has the inventory, the documentation, and the technical team to support your program.

Wire Processing & Value-Added Services

The same processing capabilities Welding Warehouse Inc offered — delivered with greater capacity and faster turnaround.

Straightening & Cutting

Precision wire straightening and cut-to-length services for TIG filler metals. Exact lengths, straight pulls, clean ends. Custom length runs with full lot traceability available.

Custom Spooling

Custom weight spools — 1 lb, 2 lb, 10 lb, 25 lb, 33 lb, and specialty reels. We spool exotic alloys other distributors won’t touch, with consistent layer winding for smooth MIG feeding.

Ultrasonic Wire Cleaning

Ultrasonic cleaning removes surface oxides, lubricant residue, and contamination from welding wire — critical for titanium, nickel, and other contamination-sensitive alloy applications.

Custom & Generic Packaging

White-label or custom-branded packaging for resellers and OEM supply programs. Generic packaging for cost-sensitive applications. Tube, sleeve, carton, and industrial pail options available.

Flag Tagging — One End or Both

Heat number, specification, alloy grade, and customer-specific information flag-tagged on one or both ends of cut-length TIG wire. Essential for traceability in aerospace and defense programs.

Wire Drawing

Wire drawing to customer-specified diameters for micro-wire and specialty alloy applications. We serve R&D, medical device, and precision instrument markets requiring non-standard wire gauges.

Why WeldTool is the Right Long-Term Partner

Bigger Operation. Better Fulfillment.

The Welding Warehouse Inc served the market well. But WeldTool Technologies was built for the next level. Our warehouse infrastructure, sourcing network, and technical team are scaled to fulfill large, complex, and recurring orders without the capacity constraints that smaller distributors face.

More Products. More Grades. More In Stock.

Beyond the standard categories, WeldTool stocks micro wire, tool steels in AISI grades, AMS-grade magnesium, ChannelFlux® and vacuum-grade brazing alloys, palladium braze alloys, and braze foil and rope — specialty materials that most distributors don’t even carry.

Technical Expertise That Comes Standard

Every order is backed by metallurgical knowledge. Our team can help you select the right filler metal, verify specification compliance, interpret data sheet requirements, and source alloys that aren’t in our standard catalog. This is the kind of expert support that makes us more than a commodity supplier.

Answers for former Welding Warehouse Inc customers and new buyers looking for specialty filler metal supply.

Is The Welding Warehouse Inc still in business?

The Welding Warehouse, Inc. (formerly at weldingwarehouseinc.com, 7654 E. Slauson Ave, Commerce, CA 90040) is no longer operational. Their website shows a PHP error and the business is closed. WeldTool Technologies is fully operational and ready to fulfill all of your filler metal and welding wire requirements immediately.

Who stocks the same AMS, AWS, and MIL-spec filler metals Welding Warehouse sold?

WeldTool Technologies stocks the complete range of specification-grade filler metals across AMS, AWS, and MIL classifications. This includes nickel alloys, titanium, stainless steel, cobalt, aluminum, copper, magnesium, brazing alloys, and mild/low alloy steel — every category The Welding Warehouse carried, plus additional exotic grades they did not.

Do you offer custom spooling, flag tagging, and wire drawing like Welding Warehouse did?

Yes. WeldTool offers all the processing services The Welding Warehouse provided: straightening and cutting, custom spooling, ultrasonic wire cleaning, custom and generic packaging, flag tagging (one end or both), and wire drawing. Contact our team to discuss your specific processing requirements.

Can you provide full traceability and mill certifications?

Absolutely. Every order from WeldTool ships with full chemical and mechanical mill certifications, traceable to heat number and manufacturing lot. We also maintain SDS/MSDS documentation and product data sheets for our complete alloy catalog — essential for aerospace, defense, and high-specification fabrication programs.

Do you stock stainless steel flux cored wire?

Yes. WeldTool stocks stainless steel flux cored wire across a range of grades and classifications for positional welding, pressure vessel fabrication, and structural applications where solid wire is not optimal.
