We like to think that beyond a certain limit, welding does not remain a simple science, but becomes an art. Unfortunately, however, we often forget that it is a special process and cannot be evaluated through simple final measurements, but must be subjected to planning, control and qualification methodologies.

C.M.&M. is an ideal partner for construction works of welded metal carpentry, heavy and light, as it is able to follow the entire welding process with IWT (International Welding Technologist) and IWI (International Welding Inspector) certified staff.

The productivity capacity of the company welding department, coordinated by the Technical Office through specific procedures (Welding Procedure Specification) and process qualifications (Welding Procedure Qualification Report), guarantees the repeatability of a convenient product, in compliance with lead times. provided with the customer.

C.M.&M. they can be certified in accordance with the following standards:
• UNI EN ISO 15614-1: Specification and qualification of welding procedures for metallic materials – Welding procedure qualification tests – Part 1: Arc and gas welding of steels and arc welding of nickel and nickel alloys.
• UNI EN ISO 15609-1: Specification and qualification of welding procedures for metallic materials – Specification of the welding procedure – Part 1: Arc welding
