The Background

Trained where failure is not an option.

For eight years, I worked as a precision TIG welder for a global leader in radiation detection and measurement. The components I built went into systems that protect workers and the public in some of the most demanding environments on earth.

That kind of work doesn't tolerate shortcuts. Every joint inspected, every parameter logged, every weld traceable. I spent nearly a decade doing TIG work in a sector where the tolerance for error is, effectively, zero. Aluminum, titanium, stainless steel, magnesium — all welded to the discipline that nuclear safety equipment demands.

I started Apex Fabrication LLC to bring that same standard to small and mid-size manufacturers in the Southern Tier — companies that need a welder who treats every joint like it has to pass nuclear inspection. Because at this level of craftsmanship, that's exactly how every weld gets treated.

The Craft

Bead character. Penetration. Consistency.

Quality indicators are visible to anyone who knows what to look for. Recent in-shop samples — no filters, no retouching, just welds under shop light.

SHOP FLOOR · NO RETOUCH
01

Bead Consistency

Even ripple pattern. No skips, no undercut, no wandering. Each pass laid with the same hand.

02

Heat Tint

Tight color band on stainless and titanium — controlled heat input, no overheating, no oxidation.

03

Full Fusion

Root penetration where the print calls for it. Strong joints, not just pretty surfaces.

04

Clean Atmosphere

Back-purge maintained where required. Critical for titanium and reactive metals — no exceptions.

Capabilities

What Apex
delivers.

Three primary services — consulting, training, and ASTM-compliant crates — rooted in the discipline of the nuclear safety supply chain. Plus custom TIG fabrication as schedule allows.

Custom TIG Fabrication

One-off TIG work, multi-material assemblies, equipment repair welds, and short-run custom fabrication across aluminum, titanium, stainless steel, and magnesium — taken on alongside the primary consulting, training, and crate work.

Material Expertise

Four materials. Four disciplines.

Each metal demands its own approach. Knowing the difference is the difference between a weld that holds and one that fails inspection.

M-01

Aluminum

Thin-gauge to structural. AC TIG with high-frequency start, balanced for cleaning and penetration.

5xxx · 6xxx Series
M-02

Titanium

Aerospace and medical-grade. Demands exceptional purity, full back-purging, and rigorous atmosphere control.

Grade 2 · Grade 5 · 6Al-4V
M-03

Stainless

Food-grade to nuclear-spec. Back-purged where required, with attention to chromium retention.

304 · 316 · 321
M-04

Magnesium

A specialist's metal. Lightweight aerospace and defense applications welded with controlled heat input.

Coverage

Based in the Southern Tier. Built to travel.

Apex Fabrication's work is centered in the Corning / Elmira corridor, with regular service to manufacturers throughout the Southern Tier — Bath, Hornell, Ithaca, Binghamton, and the surrounding region.

But the work I came up in served clients across the country and around the world. For the right project — on-site consulting, weld training, or specialized fabrication — Apex travels.
