Welded structures

In addition to welding all types of steel and stainless steel, we also focus on the welding of aluminium alloys. We employ highly qualified welders certified according to the European standards. We most commonly used the MIG/MAG and TIG/WIG methods.

Why opt for welded structures from Zihos?

We weld steel, stainless steel and aluminium alloys.
We weld small and large structures.
Professional team of welders including a welding engineer.
We handle both piece-work and series production.
For the series production sector, we manufacture own automatic welding machines = lower contract price

Manufacturing of own structures and frames

In 2015, we acquired a press brake, which enables us to bend and weld own structures from sheet-metal and profiles. We can thus offer the custom design and manufacturing of various bent and welded structures to the customer, for instance, welded machine and equipment frames (length 4.5 m, height 2 m, width 2 m, weight up to 3 tonnes), etc.

Series and piece-work production

We also weld small parts using own jigs, as well as large dimension and heavy-weight welded structures. We perform piece-work and serial production for our customers. In this segment, we are capable of offering a relatively interesting price. The reason for this consists in the automatic welding machines, which we make for use in series production. In this way, we are capable of improving the efficiency, automation and end price of the work. In series, we annually make up to several hundred units.

At Zihos, we pay attention to the professionalism of our employees

All of our welders have accomplished welding tests according to the standard and we also have a certified welding engineer. We are making long-term efforts to employ top-quality people from the region and provide them with professional training. We are convinced that this philosophy will enable us to even compete with the disproportionately larger companies in the Czech Republic.

TIG welding

Tungsten Inert Gas (TIG) welding technology is an arc-welding process that produces the weld with a non-consumable tungsten electrode in an inert gas shield atmosphere. During the welding process, the electrode is exposed to extreme temperatures and should thus be made of resistant material. For this reason, Tungsten (Wolfram) electrodes are used. The TIG method is also known as WIG welding – this is an identical method. The main advantage of the TIG method is precision and high level control over the weld pool. TIG welding is mainly applied in the welding of steel. This method is used to weld:

thin joints and materials
sophisticated and smaller welded structures made of quality metals (wheel and motorcycle frames, decorative items, etc.)
boiler pipes in energy engineering and others

MIG welding

It is semi-automatic arc-welding of metals in an inert gas shielded environment – the acronym MIG is derived from the English term “metal inert gas”. MIG welding is particularly used to weld aluminium and other general light metals. Argon, or its mixture with Helium, is the most commonly used inert gas in MIG welding. In addition to the welding of aluminium, it can also be used to weld copper (including its alloys – particularly, bronze) and titanium.
