Description
Technical field
The utility model relates to the heat exchange equipments such as air cooler and composite cold and pressure vessel angle joint one side welding with back formation
Welding field more particularly to a kind of groove for angle joint abutment joint one side welding with back formation.
Background technique
The joint form of the heat exchange equipments core component such as air cooler and composite cold is mostly angle joint form, in D type structure
Chamber size is smaller, personnel can not in internal welding, currently, the country be all made of artificial argon arc welding single-side welding double-side forming technology with
Meet product quality requirement, but artificial argon arc welding low efficiency, quality are limited by welder's level of skill, when output is big again
It is difficult to recruit suitable welder, production task is restricted repeatedly, using the automatic weldings mode such as robot, is limited by vertical plate and transverse slat
Not uniform thickness, the welding of conventional groove are difficult to accomplish single-side welding double-side forming, often occur burning or the defects of incomplete fusion, and weld
Process is discontinuous, is especially difficult to meet the requirement of UT flaw detection.
In view of the foregoing, a kind of groove for angle joint abutment joint one side welding with back formation is now developed.
Utility model content
The purpose of this utility model is to overcome deficiencies in the prior art, provide a kind of for angle joint abutment joint list
The groove of two-sides forming is welded in face, and groove type is simple, easy processing, and group is to convenient, solderability height, in automatic welding similar to angle joint
When, single-sided welding two-sides forming, and the requirement that UT detection is qualified can be easily reached.
The utility model to achieve the goals above, adopts the following technical scheme that a kind of for angle joint abutment joint single side
Weld two-sides forming groove, be by: vertical plate, half U-shaped groove, U-board, half V-butt are constituted；U-board, U is arranged in vertical plate side
Shape plate and vertical plate are mutually perpendicular to constitute D-shape configuration, and vertical plate upper and lower ends are symmetrical arranged a pair of of half U-shaped groove towards U-board side,
U-board is symmetrical arranged one and half V-butts towards the both ends of vertical plate, at the half U-shaped groove bottom margin of vertical plate and U-board half
The docking of V-butt root constitutes welding filling cavity between the half U-shaped groove of vertical plate and half V-butt of U-board.
The cambered surface radius of the half U-shaped groove is R, and R is 4~8mm, R ± 2mm.
The inclined-plane extended line of the half U-shaped groove and the angle of half U-shaped groove vertical centre extended line are α 2, and α 2 is 8
~12 °.
Angle between the slope surface and bottom surface of half V-butt is α 1, and α 1 is 55~70 °.
Welding method: the both ends of vertical plate are higher by the both ends 6mm of U-board, to form fillet weld, the half U-shaped groove of vertical plate
Root and U-board half V-butt root alignment, upper lower deviation 1mm, welding parameter setting, electric current 300A, voltage 12V,
Along weld movement 60~100mm/min of speed, tungsten electrode swings to vertical plate side and stops 0.3~1s tungsten electrode, swings to the stop of transverse slat side
0.1~0.6s after completing bottom welding, continues to fill up one layer using MAG welding, then turns SAW and complete filling and capping.
The beneficial effects of the utility model are: the R arc of this technique half U-shaped groove can increase, the offset of R arc can also increase,
The increase of above 2 sizes will not influence one side welding with back formation quality, but will increase loading, and then influence efficiency, this
The groove type of technique is simple, easy processing, and for group to conveniently, solderability is high, when automatic welding is similar to angle joint, can be easily reached
Single-sided welding two-sides forming, and the requirement that UT detection is qualified.
