(1) 小径管环向对接焊接接头的透照布置
小径管采用双壁双影透照布置,当同时满足下列两条件时应采用倾斜透照方式椭圆成像
a) T(壁厚)≤8mm
b) g(焊缝宽度) ≤D0/4
椭圆成像时,应控制影响的开口宽度(上下焊缝投影最大间距)在1倍焊缝宽度左右.
不满足上述条件或椭圆成像有困难时可采用垂直透照方式重叠成像.

Pipe ring (1) the path to the butt welded joint of transillumination layout
Small tube with double-wall double transillumination decorate, while at the same time satisfy the following two conditions should be tilted transillumination mode elliptic imaging
A) T (wall thickness) 8 mm or less
B) g (weld width) D0/4 or less
Elliptical imaging, should control affect the opening width of the (weld projection maximum spacing) up and down at about 1 times the width of the weld.
Do not meet the above conditions or elliptical imaging have difficulty can adopt vertical transillumination mode overlapping imaging.
