THE WELDING PROCESS:
JUMBO PRO STEEL owns welding procedures acknowledged for the following welding methods: manual electric welding, automatic and partly-automatic welding in protective shield (CO2 and argon) and automatic welding under flow bed.
JUMBO PRO STEEL has a certified staff, authorized to carry on weldings according to ISCIR, ASME Code and TUV. The welded joints are checked through nondestructive tests.
The nondistructive tests used by our company are:
- radiographics (X-rays, gamma)
- magnetic powder
- dye penetrant
- ultrasonic tests
JUMBO PRO STEEL has CND staff qualified in the levels 1, 2, 3 depending on education, professional training and physical abilities.
