Stainless steel welding for assemblies in industrial and plant construction

Many stainless steel constructions look impressive in CAD but fail in production due to warping, reworking, and time-consuming assembly. With a well-thought-out approach to stainless steel welding, Deckert ensures that your assemblies come out of production just as you planned them.

Overview of welding techniques for stainless steel welding

Different shielding gas processes are suitable for welding assemblies made of stainless steel. It is crucial to determine which process is used at which part of the component.

Shielded arc welding for load-bearing areas

Many load-bearing connections are made using shielding gas processes that are designed for stable penetration and reproducible seams. They form the foundation when frames, supports, or brackets need to reliably carry loads.

MIG welding for productive stainless steel assemblies

MIG welding is suitable for areas with series production and a focus on throughput. Frames and frameworks, where the seam is not directly visible later, can be produced economically in this way without neglecting the mechanical function.

TIG welding for visible and thin-walled zones

TIG welding is used when seams remain visible or when thin-walled stainless steel parts need to be joined. The heat input can be finely controlled so that dimensional accuracy and seam appearance are maintained even in sensitive areas.

In many projects, the techniques are combined. Load-bearing sections are designed for throughput, while visible details are implemented with higher demands on aesthetics.

When stainless steel welding is the right choice

Stainless steel is always worthwhile when the environment and stress require more than conventional structural steel.

Typical situations include:

Assemblies in a damp or chemically aggressive environment
Constructions that are regularly cleaned
Load-bearing elements that remain permanently in the visible area
Retrofitting where steel components are to be replaced by stainless steel

In these applications, not only the choice of stainless steel is important but also how the construction is welded and processed. If the welding sequence, heat input, and processing do not match, distortion, additional straightening, and delays in assembly occur.

How a typical stainless steel welding order proceeds

1. Review documents and key data

At the beginning, we review your drawings, models, or sample parts and clarify together what functions the assembly should fulfill. You receive feedback on which areas are critical for production and where small adjustments can save effort in future production and assembly.

2. Define welding concept

Based on this, we determine how the component will be clamped, tacked, and welded. The joining sequence, order of the seams, and suitable clamping devices are chosen so that distortion remains manageable and all areas are easily accessible. You receive a comprehensible plan for how your construction will be implemented in stainless steel welding.

Stainless steel welding in defined procedure

The welding work follows a defined scheme, tailored to material thickness, geometry, and requirements for visible surfaces. This produces reproducible results, and you can rely on the fact that even series components match the drawing.

4. Mechanical processing and surface preparation

After welding, mating surfaces, holes, or reference edges are machined. We prepare the surface in such a way that further steps like coating or corrosion protection solutions can follow seamlessly.

Your advantages with Deckert in stainless steel welding

Welded assemblies that work in assembly

Even in the planning phase, we consider how the assembly should be mounted later. The welding sequence, clamping concept, and machining are designed so that parts fit together in reality and do not need to be adjusted on site.

Less rework due to coordinated machining

Welding and machining complement each other. Functional surfaces and holes are created after welding in relation to the real part. This reduces the need for rework and minimizes adjustments during assembly.

Certified welding with clear procedures

The welding is certified according to DIN EN ISO 3834-2 and DIN EN 1090-1/-2. Certified welders according to DIN EN ISO 9606-1 and welding supervision at engineering level ensure that your stainless steel welding constructions meet the required standards.

One contact person for the entire process

You discuss your stainless steel welding with a partner who knows the entire process. From the first concept to the finished part, the process remains in one hand, interfaces are minimized, and queries can be clarified directly.

Typical applications in stainless steel welding

Stainless steel welding constructions by Deckert are found in various industries and fields.

Common examples include:

Frames and structures in plant and mechanical engineering
Brackets and consoles in damp or clean-intensive areas
Hygienic assemblies with direct media or food contact
Conversions and extensions where existing steel assemblies are replaced with stainless steel

It is important for all projects that the assemblies function in everyday use and do not just look good on the drawing. Therefore, we coordinate welding, machining, and surface from the beginning.

Stainless steel welding planned instead of reworked

Are you planning a new stainless steel welding assembly or do you want to adapt existing constructions and are looking for a partner who aligns processes, welding sequence, and machining to your specific application from the start? Send us your drawings or describe your task. Based on this, you will get a clear assessment of how stainless steel welding can be implemented technically sound and economically for you.
