revised: Customer process cladding in the Welding & Cutting sector

Cladding

Change of surface properties

PROCESS DESCRIPTION

The aim of coating construction components is to create surface properties that the base material does not have. Important characteristics include:

  • Corrosion resistance
  • Wear resistance
  • Thermal or electrical resistance or conductivity
  • Optical properties

Often it is metals that are coated. Here methods are used whose principles of operation are known from joining technology, such as:

  • Soldering
  • Electric arc welding
  • Shield gas welding,
  • Plasma-powder welding

For heat sensitive or non-metallic components special processes have been developed, such as:

  • Thermal spraying
  • Vacuum-coating
  • Electro- or immersion bath-galvanisation
  • Chrome plating

null Calibration Gases - Introduction 2b

The ISO 17025 specifies the general requirements for the competence of testing and calibration laboratories. For example, a laboratory accredited according to ISO 17025 has proven its competence to carry out calibration as well as to manufacture and analyze gas mixtures. 

The ISO 17034 describes the general requirements for the competence of reference material producers. A manufacturer accredited according to ISO 17034 is competent to produce certified reference materials (CRMs). 

In general, a calibration gas certified by an accredited laboratory play an important role in analytical chemistry as they satisfy the highest metrological standards. Calibration gases are primarily used in laboratories, which are subjected to GMP or ISO 17025 regulations.

In Europe, Messer operates four laboratories with an accreditation according to ISO 17025. 

Our plant in Switzerland is accredited according to ISO 17034, thus we have the competence for manufacturing certified reference materials (CRMs). As a manufacturer of certified reference materials (CRMs), we proved the reliability of our processes, validated our technical expertise and showed our commitment to quality. 

Our long-term experience in manufacturing and analyzing individual calibration gas mixtures and the skills of our teams enable us to offer highly accurate and traceable products.
