Laser marking

De.Ma. produces stainless steel tubes from cold rolled strips. The process takes place online inside a chamber in an inert atmosphere. The electro-welding process takes place without filler metal. This process guarantees the perfect maintenance of the structure and the material which remains unaltered.

Our products are tested by carrying out welding bend tests, expansion tests, flattening tests, in-line Eddy Current tests, tensile tests, hardness tests.
