Supervision and control

Technical documentation for welding must contain all the data for preparing, welding, and controling of welding joints and details about:

  • basic material, product size and dimension
  • welding process and additional welding material
  • shape and dimension of weld
  • preheating and heat intake during welding
  • heat treatment after welding
  • subsequent treatment of weld
  • testing the method and volume
  • requirements applied for welding joints, quality, accepted tolerance, etc.

„PONDT“ D.O.O. COMPANY, WITH OUR CERTIFIED EXPERTS, OFFERS A COMPLETE SERVICE FOR SUPERVISION, CONTROL, AND TESTING OF WELDING JOINTS WITH NON-DESTRUCTIVE METHODS.

Methods

Radiographic testing

Radiography is a process of recording inner and outer defects in three-dimensional objects on a two-dimensional film plane.

Ultrasonic testing

Ultrasonic testing is based on the fact that solid materials are good at carrying sound waves.

PAUT- Phased array ultrasonic testing

An advanced method of ultrasonic testing that has applications in industrial nondestructive testing.

Magnetic testing

With the use of magnetic flux it is possible to find flaws on the surface of the object as well as directly below the surface.

Penetrant testing

Penetrant testing is one of the first widely accepted non-destructive testing method.

Visual inspection

Visual inspection is the oldest and the most common non-destructive testing method.
