Background technology
Flat-bulb steel is a kind of medium section being mainly used in shipbuilding and bridging field, and wherein Flat-bulb Steel for Ship Use is that shipbuilding is with auxiliary
Help medium section.Recently as the fast development of shipbuilding industry, Flat-bulb Steel for Ship Use is in great demand.Generally large ship and regular
Boats and ships main hull when design selects Flat-bulb Steel for Ship Use mostly, uses the flat-bulb steel with consecutive panels same thickness with material to make bone
Material (also referred to as muscles and bones or Os Draconis).And its flat-bulb steel welding procedure has become one of important key technical index of its shipbuilding.Existing
Welding technique is had generally when with automatic fillet welding dolly welding flat-bulb steel, pore can often to occur so that appearance of weld is the most beautiful
Seeing, quality also can not be guaranteed, the most troublesome, operator requiring, height, labor intensity also increase, has a strong impact on it
Welding quality and aesthetic property, not enough for its existing welding technique, the present invention provides the angle of a kind of new Flat-bulb Steel for Ship Use
Weldering welding technique.
Summary of the invention
It is an object of the invention to provide a kind of Flat-bulb Steel for Ship Use fillet welding welding technique, be used for solving in existing welding procedure
Easily produce the technical problem of bubble, and then make face of weld beautiful appearance that flat-bulb steel fillet welding is welded, inside once detect a flaw conjunction
Lattice rate is high, and this welding technique simultaneously, operating characteristics is higher, greatly reduces labor intensity.
For reaching above-mentioned purpose, technical scheme proposed by the invention is:
A kind of Flat-bulb Steel for Ship Use fillet welding welding technique of the present invention, it comprises the following steps:
The first step, is grouping the deck of boat with flat-bulb steel, and ensures that the deck of boat and flat-bulb steel are undeformed；
Second step, brushes polishing to the rounded portions (1) of flat-bulb steel；
3rd step, uses flux-cored wire gas shield welding mode butt welded seam to weld, and makes the rifle head of welding gun inclined with weld seam face
Angle.
Wherein, also include before the described first step: the deck of boat and flat-bulb steel are carried out the step of the pre-heat treatment.
Wherein, in described 3rd step, group 30-50mm a length of to tack welding, spacing is 350-500mm.
Wherein, when the weld seam needing staggered intermittent to weld, first to rule before welding and weld afterwards.
Wherein, when hull structural member uses interval angle weld seam, in the specific length of cornerite weld seam, two-sided continuous angle is used
Weld seam.
Wherein, during hull structural member pole ends chamfering, the length of cornerite weld seam is not less than the height of component and not less than cutting plagioclase
Degree.
Wherein, also include after described 3rd step: if welding deformation is beyond code requirement, answer firer to smooth, and by regulation
Carry out the step of flaw detection inspection declaration.
Flat-bulb Steel for Ship Use fillet welding welding technique disclosed by the invention, it is when the deck of boat is with flat-bulb steel welding, in advance
First the rounded portions (1) to flat-bulb steel brushes polishing, thus produces bubble when solving fillet welding welding, causes welding quality
The highest problem.
Accompanying drawing explanation
Fig. 1 is the flow chart of Flat-bulb Steel for Ship Use fillet welding welding technique of the present invention；
Fig. 2 is Flat-bulb Steel for Ship Use structural representation of the present invention；
Wherein: 1 is flat-bulb steel rounded portions.
Detailed description of the invention
Below with reference to accompanying drawing, the present invention is given elaboration further.
Refer to accompanying drawing 1, in this embodiment, this Flat-bulb Steel for Ship Use fillet welding welding technique, comprise the following steps:
First step S1, is grouping the deck of boat with flat-bulb steel, and ensures that the deck of boat and flat-bulb steel are undeformed；
Second step S2, brushes polishing to the rounded portions (1) of flat-bulb steel；
3rd step S3, uses flux-cored wire gas shield welding mode butt welded seam to weld, and makes the rifle head of welding gun with weld seam face in inclining
Oblique angle.
Describe in detail this Flat-bulb Steel for Ship Use fillet welding weldering with the mother metal of one of which material and welding material model below
Connect process.
Mother metal is as shown in the table with welding material model:
Welding process requirement is as follows:
This technique is mainly used in the fillet welding of flat-bulb steel and the deck of boat, group to front it should be noted that should check whether the deck of boat and flat-bulb steel have relatively
Large deformation, if having, it is necessary to be grouping after re-calibrating again；Flat-bulb steel rounded portions (1) can be caused during due to steel plate pretreatment
Paint blocked up, it is necessary to flat-bulb steel rounded portions (1) (with the part of hull contact bonding) is brushed polishing.
Wherein, it should be noted that claimed below before welding:
Require to determine whether preheating according to operation card；Tack welding a length of 30-50mm during group pair, spacing is advisable with 350-500mm；
If flat-bulb steel and deck of boat position to be welded have welding slag, rust etc. to carry out purging, brush or polishing before formal welding.During welding
Should require to carry out according to welding condition, it should be noted that monitoring weldquality；Surface quality problems as serious in found continuous print,
Welding should be stopped immediately, until could welding again after solution problem.Must strictly control Size of welds, it is impossible to arbitrarily strengthen weldering
Foot size.If construction drawing requires the weld seam of staggered intermittent weldering, first to rule before welding and weld afterwards.
When hull structural member uses interval angle weld seam, following position is used two-sided the specific length planted agent of cornerite weld seam
During the pole ends chamfering of continuous fillet weld: component ends, particularly component, the length of its cornerite weld seam should be not less than the height of component
And not less than cutting plagioclase degree.
The end of the otch of various components, corner cut and discharge orifice, air-vent etc., is mutually perpendicular to the infall of component, when
When thickness of slab is more than 12mm, the length of cornerite weld seam should be not less than 75mm, when thickness of slab is less than or equal to 12mm, and its cornerite fusion length
50mm should be not less than.
When the component angle weldings such as aggregate/stiffener intersect with jigsaw seam, intersection point both sides at least 50mm sequential welding；When aiding the strong
When the components such as material have bracket to be connected, bracket end the most at least 50mm sequential welding.
Postwelding such as welding deformation exceeds code requirement, answers firer to smooth, and is carried out in accordance with regulations flaw detection inspection declaration.
Foregoing, only presently preferred embodiments of the present invention, be not intended to limit embodiment of the present invention, and this area is general
Logical technical staff, according to the central scope of the present invention and spirit, can carry out corresponding flexible or amendment very easily, therefore this
The protection domain of invention should be as the criterion with the protection domain required by claims.
