Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, right
The present invention is further elaborated.
A kind of T connector submerged welding process, comprises the following steps:
A. offering groove on web 1, described groove is that K-type is arranged；
B. wing plate 2 and web 1 group is found into component；
Liner 3 is installed at groove 7 the most overleaf, component is adjusted on ship type moulding bed 4；
D. weld: the bottoming welding of first front, then carry out sealing run welding, finally carry out front other weld seams weldering
Connect.
Specifically, to select suitable welding material according to maternal instinct material, in described step A, groove arranges shape before
Formula is the asymmetric groove of K-type, can guarantee that postwelding angular deformation is minimum, and groove is that zero root face is arranged, and front bevel angle is 50 °,
Underside groove angle is 55 °.
In described step B, employing group is found machine and is completed wing plate 2 and web 1 group and stand, and the group of wing plate 2 and web 1 is stood gap and is
Zero, and use double-sided symmetrical tack welding to position, described tack welding thickness is more than or equal to 3mm, a length of 45-50mm, and spacing is
500-600mm。
In described step C, liner 3 is ceramic substrate 3, and liner 3 angle is consistent with underside groove angle, is installing liner
Before 3, underside groove is polished, closely can be as the criterion with underside groove laminating with ceramic substrate 3 after polishing, it is ensured that lining
Pad 3 is tight with underside groove laminating, and liner 3 is fitted in underside groove by aluminum foil and adhesive tape and separate paper, is finally adjusted to by component
Preparing welding on ship type moulding bed 4, the angle of inclination of ship type moulding bed 4 is 30 °.
In described step D, bottoming welding in front uses the double filament submerged-arc welding of single supply to weld.Described pair of filament is adopted
With series system, while keeping big energy input, effectively shunt welding current, thus reduce arc energy and too much concentrate on
Groove root, makes motlten metal under surface tension and ceramic substrate 3 rest, reaches balance and form weld seam.Front bottoming welding
