Since 1977 BARUZZI SALDATURE is situated in Vobarno and is specialized in welding and metal working.
The company operates in the following application fields:

What is Welding
Welding is a junction process that permanently joins previously separated solid objects. The benefit of welding compared to other kind of joints (for example bolting, stapling, nailing, pasting) is to obtain continuity of material which result is a monolithic final product.

Metallic continuity enables to distribute the stress to which the welded piece is subject, on all its structure; therefore, in order to produce welded joints where the pressure power is correctly balanced, (to prevent the piece from breaking) it is required an accurate knowledge of processes, materials and welding alloys. Baruzzi Saldature has achieved this knowledge through a 30 years' experience in the field of welding.

In welding a filler metal is usually spread in a melted state between the edges of the pieces to join, which form the base material. Autogenous welding is when a certain amount of base material is fused in addition to the filler material. Braze welding is when the base material is not melted but only heated; in this case the filler material has a lower fusion temperature than the base material one.

Weldability is the attitude and reaction of the material in the production of welded joints with desired characteristics. This peculiarity is not definable on a whole scale but just step by step. Furthermore, if the weldability degree of material is low, higher precautions are required for the execution of each welding process.

History of welding
Since Middle ages was performed the union of iron parts which were heated on the forge and then hammered in order to make them homogeneous.

Reproducible pieces, realized with the welding process were obtained in the first years of 1900 through the oxyacetylene welding. With this welding method the parts were joined through the fusion of their edges and the power required for the fusion of the pieces was supplied from the gas combustion, in this case the acetylene, with the pure oxygen. The high temperature which are reached with this process produce welded joints that doesn't require hammering and contribute to increase the repeatability and the simplicity of the welding process.

In the 20th century a new method was introduced, which consisted in utilizing an arc, powered from electric generators, with necessary power for iron fusion. This first unprotected electrode process, which tooks advantage on the utilize of the arc, was substituted from the coated electrode method, which grants a higher quality of welded joints.

In 1925 resistance welding process was developed and was used in the industrial area for large scale production items. During the second world war a higher productivity normally given from the use of coated electrode was required, therefore in USA the study of the continuous wire feed and submerged arc begun; these methods enabled a higher and reproducibility than the ones given by coated electrode system.

In the postwar period were developed the MIG and MAG procedures, which granted a productivity similar to the one given by the submerged arc, but they had a higher number of application forms. In the same period TIG welding was also developed and allowed a more precise control of the characteristics of welding metals and a continuous working process.
