Company introduction
The welding seam direction is only allowed to be radial and
circumferential.In the future, this requirement may be removed for
large pipe caps.The splicing distance should be more than 3δ, and
not less than 100mm(welding heat affected zone is a high stress
zone, and the chemical composition in this area will burn loss.So
avoid high stress areas, which are related to thickness.According
to practical experience, the stress attenuation length is greater
than 3δ, and not less than 100mm).But refrigeration equipment is
difficult to achieve this requirement, has its particularity.
After splicing the head, splicing weld should be 100% ray or
ultrasonic test, the qualification level goes with the equipment
shell.The welding seam detection level and proportion of the final
forming are the same as that of the equipment shell, which leads to
high waste.For example: if the equipment shell is 20% tested, III
qualified.The straight splicing weld and the final weld are also
III qualified, with a welding joint coefficient of 0.85;
If the equipment shell is 100% tested, II is qualified.The splice
weld and the final weld are also II qualified with a joint
coefficient of 1
So although the head splicing is 100% detected, the qualification
level is not the same, and it goes with the equipment shell.
