Abstract
The present invention relates to welding field, a kind of girth welding technique is specifically disclosed.The circular-seam welding method, it is characterised in that：To cover first and process that seam position outer ring that itchy process contacts on anchor ring in capping with cylinder grafting is a circle and vertical diameter row face is in 32.5 degree of slope anchor ring with cylinder grafting contact site, the axial circular cylinder root explained in detail in 32.5 degree of radial direction slope anchor rings and axial circular cylinder is a circle wide 1.5 millimeters, deep 0.5 millimeter scrobicular ring, cylinder is a thick 0.3 millimeter circle along bottommost with the lower of the capping of insertion, the base ring side of 0.5 millimeter of money, it is a circle and vertical sagittal plane in 32.5 degree of slope anchor ring against the lower edge of base ring side sealing cover, welded at trapezoidal position again.The beneficial effects of the invention are as follows：It is welded together with capping, melts cylinder transverse direction position and weld, reach the thickness requirement of welding position, reaches seal request.
Description
Technical field
The present invention relates to welding field, specially a kind of girth welding technique.
Background technology
At present, aluminium alloy cylindrical body welding portion requirement with pressure reaches certain sealing intensity requirement, but original aluminium alloy cylindrical body and when being sealed on welding, contact anchor ring and be processed into seam with cylinder in capping, it is processed into domatic in seam root, cylinder mouthful is inserted into capping seam root again, footpath row argon arc welding welding, because the capping of welding position can absorb some heats, solder flux and wlding can not go deep into inside circumferential weld volume, weld seam anchor ring can not melt completely, and welding position is shallower, and welding does not reach sealing intensity requirement.
The content of the invention
The technical problems to be solved by the invention are：A kind of circular-seam welding method is provided.Solder flux and solder can go deep into inside circumferential weld, and welding anchor ring reaches and melts completely, behind welding position, reaches sealing intensity pressure ball.
The technical scheme is that：
A kind of circular-seam welding method, it is characterised in that：To cover first and process that seam position outer ring that itchy process contacts on anchor ring in capping with cylinder grafting is a circle and vertical diameter row face is in 32.5 degree of slope anchor ring with cylinder grafting contact site, the axial circular cylinder root explained in detail in 32.5 degree of radial direction slope anchor rings and axial circular cylinder is a circle wide 1.5 millimeters, deep 0.5 millimeter scrobicular ring, cylinder is a thick 0.3 millimeter circle along bottommost with the lower of the capping of insertion, the base ring side of 0.5 millimeter of money, it is a circle and vertical sagittal plane in 32.5 degree of slope anchor ring against the lower edge of base ring side sealing cover, welded at trapezoidal position again.
The beneficial effects of the invention are as follows：In annular groove inside solder flux and the deep enough weld seam of solder energy, welding base ring face on cylinder is due to there is a hanging face, welding gun forms small molten bath when striking sparks with trapezoidal trench bottom, and welding heat will not be passed to away, and this for concentrating on base ring face on cylinder hanging is changed on face, heat is not lost in, the anchor ring for enabling this hanging reaches and melts completely, is welded together with capping, melts cylinder transverse direction position and welds, the thickness requirement of welding position is reached, seal request is reached.
Specific embodiment
Aluminium alloy cylindrical body welding portion requirement with pressure reaches certain sealing intensity requirement, but original aluminium alloy cylindrical body and when being sealed on welding, in capping and cylinder contact anchor ring is processed into seam, seam root be processed into it is domatic, then will capping seam root insertion cylinder mouthful, footpath row argon arc welding welding, because the capping of welding position can absorb some heats, solder flux and wlding can not go deep into inside circumferential weld volume, and weld seam anchor ring can not melt completely, welding position is shallower, and welding does not reach sealing intensity requirement.
The technical problems to be solved by the invention are：A kind of circular-seam welding method is provided.Solder flux and solder can go deep into inside circumferential weld, and welding anchor ring reaches and melts completely, behind welding position, reaches sealing intensity pressure ball.
A kind of circular-seam welding method, it is characterised in that：To cover first and process that seam position outer ring that itchy process contacts on anchor ring in capping with cylinder grafting is a circle and vertical diameter row face is in 32.5 degree of slope anchor ring with cylinder grafting contact site, the axial circular cylinder root explained in detail in 32.5 degree of radial direction slope anchor rings and axial circular cylinder is a circle wide 1.5 millimeters, deep 0.5 millimeter scrobicular ring, cylinder is a thick 0.3 millimeter circle along bottommost with the lower of the capping of insertion, the base ring side of 0.5 millimeter of money, it is a circle and vertical sagittal plane in 32.5 degree of slope anchor ring against the lower edge of base ring side sealing cover, welded at trapezoidal position again.
The beneficial effects of the invention are as follows：In annular groove inside solder flux and the deep enough weld seam of solder energy, welding base ring face on cylinder is due to there is a hanging face, welding gun forms small molten bath when striking sparks with trapezoidal trench bottom, and welding heat will not be passed to away, and this for concentrating on base ring face on cylinder hanging is changed on face, heat is not lost in, the anchor ring for enabling this hanging reaches and melts completely, is welded together with capping, melts cylinder transverse direction position and welds, the thickness requirement of welding position is reached, seal request is reached.
Certainly, described above is not limitation of the present invention, the present invention is also not limited to the example above, those skilled in the art, in essential scope of the invention, the change made, remodeling, addition is replaced, should all belong to the present invention it should be understood by those skilled in the art that, the present invention is not limited to the above embodiments, merely illustrating the principles of the invention described in above-described embodiment and specification, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these changes and improvements all fall within the protetion scope of the claimed invention.The claimed scope of the invention is by appending claims and its equivalent thereof.
