Structural Reinforcement

We don't just patch; we reinforce. Whether it's a cracked aluminum boat hull or a heavy equipment boom, our repairs are engineered to be stronger than the factory original.

Why We Back-Purge

Oxidation is the enemy. At DudeRacing, all stainless steel exhaust components are back-purged with argon. This prevents "sugaring" (internal crystallization) inside the pipe, ensuring laminar flow and preventing structural cracking under thermal cycling.

Many shops skip this step to save gas and time. We don't. A weld that looks good on the outside but is crystallized on the inside creates turbulence and weak points. Whether it's a 1500+ hp twin turbo build or a simple exhaust repair, the atmosphere is purged before the arc is struck.

Engineering Process

1

Consultation & Mockup

Measurement / Physical Mockup to define packaging constraints.

2

CAD & Material Selection

Design validation. Choosing Schedule 10/40 vs. Thin Wall.

3

Precision TIG Welding

Strict back-purging protocols. Sanitary welds. Void-free penetration.

4

Finish & QC

Pressure testing, surfacing flanges, and Cerakote options.
