precision and control in stainless steel fabrication
For stainless steel pressure vessels, weld quality and precision are key.
At Deprest, we use Plasma Arc Welding (PAW) to achieve both — combining high energy density with exceptional process stability.
PAW produces narrow, smooth and deeply penetrating welds with minimal heat distortion, making it ideal for thin or polished stainless steel shells.
The result is a clean, uniform weld seam that meets the highest visual and technical standards.
In the photo, you can see our two PAW installations in action:
In the foreground, our clamping bench for longitudinal welds, designed for perfect alignment and straightness.
In the background, our second PAW setup, used for circumferential welds, vertical vessel assembly, and special longitudinal seams.
By mastering multiple welding techniques — including PAW, TIG, MIG/MAG, and SAW — Deprest delivers superior quality and consistency across every type of pressure vessel.
Plasma precision at work — Deprest quality in every seam.
