1. Weld Procedures

MATCO can provide a full-time Welding Engineer at your facility to develop and document required welding procedures. Documentation will be on your company letterhead, as required by code. MATCO will arrange for full testing and evaluation of the welded test plates, including chemical, physical and non-destructive means of study. Typical means of testing:

- Radiographic, ultrasonic, magnetic particle, dye penetrant inspection Through NDT Group.
- Microscopic and metallurgical examination.
- Corrosion and stress-corrosion testing.
- Tensile tests, bend tests, charpy impact tests and hardness tests.
- Prepare Procedure Qualification Records (PQR's) and Weld Procedure Specifications (WPS's).
