| description | A titanium layer of the small-caliber titanium steel composite pipe is arranged inside, a steel layer of the small-caliber titanium steel composite pipe is arranged outside, symmetrical V-shaped grooves are formed, the angle of the single-side groove of the steel side is 30 +/-5 degrees, and no truncated edge is left on the steel side; the single-side stripping length of the titanium layer is 2-3mm, and the single-side groove angle of the titanium side is 30 +/-5 degrees. The invention further discloses a welding method for the circumferential weld of the small-caliber titanium steel composite pipe. The method solves the problems that when the small-caliber titanium steel composite pipe is welded, operation is difficult, and the joint quality is poor.
本发明公开小口径钛钢复合管环焊缝坡口形式，该小口径钛钢复合管的钛层在内，钢层在外，开对称型V型坡口，钢侧单边坡口角度为30±5°，钢侧不留钝边；钛层单侧剥离长度为2～3mm，钛侧单边坡口角度为30±5°。本发明还公开了小口径钛钢复合管环焊缝焊接方法，该方法解决了小口径钛钢复合管焊接时操作困难、接头质量差的问题。 |
