Abstract
The invention provides a circular-seam welding method, which comprises the following steps that: an insertion contact part of a sealing cover and a cylinder body is machined; an outer ring of a spigot part formed on the sealing cover is a slope ring surface at an angle of 32.5 degrees; an axial cylindrical surface root where a radial slope ring surface and an axial cylindrical surface are connected is a concave ring; the bottommost part of the lower edge of the sealing cover is a bottom ring edge; the lower edge of the sealing cover abutting against the bottom ring edge is a circle of slope ring surface at an angle of 32.5 degrees; after the sealing cover and the cylinder body are in inserted connection, the slope ring surface on the sealing cover and slope ring surface on the cylinder body form a trapezoidal groove of which the bottom has a ring surface; and then the trapezoidal groove is welded. Flux and solder can penetrate into a ring groove inside a circular seam, and the bottom ring surface on the cylinder body has a hanging ring surface which forms a small weld pool with the bottom of the trapezoidal groove when a welding gun is struck, so welding heat cannot be conducted out. No loss of heat ensures that the hanging ring surface can be completely melted and welded to the sealing cover so as to melt and firmly weld the transverse part of the cylinder body. Therefore, the method meets the requirements on the thickness of welded parts and sealing strength.
Description
Technical field
The invention belongs to welding method, particularly a kind of circular-seam welding method of aluminium alloy tube jar class.
Background technology
Aluminium alloy cylindrical body welding portion with pressure requires to reach certain sealing intensity requirement.But when original aluminium alloy cylindrical body and capping welding, in capping, contact anchor ring and be processed into seam with cylindrical shell, the seam root is processed into domatic, again capping seam root is inserted the cylindrical shell mouth, carry out the argon arc welding welding, because the capping meeting of welding position absorbs some heats, solder flux and scolder can not go deep into circumferential weld inside, the welding anchor ring can not melt fully, and the welding position is shallow.Welding does not reach the sealing intensity requirement.
Summary of the invention
Technical problem to be solved by this invention is: a kind of circular-seam welding method is provided.Solder flux and scolder can go deep into circumferential weld inside, and the welding anchor ring reaches fusing fully, and the welding position is thick, reaches the sealing intensity requirement.
Technical scheme of the present invention is:
A kind of circular-seam welding method is characterized in that: at first with capping and the processing of cylindrical shell grafting contact site; Being formed in the capping outer ring, seam position that contacts on the anchor ring with cylindrical shell is that a circle is 32.5 ° slope anchor ring with vertical sagittal plane, and the axial cylindrical face root that joins at 32.5 ° radially slope anchor rings and axial cylindrical face is one to enclose wide 1.5mm, the scrobicular ring of 0.5mm deeply; The lower edge bottommost of the capping of cylindrical shell and insertion is the thick 0.3mm of a circle, the base ring limit of wide 0.5mm, and the lower edge of covering near the base ring banding is that a circle is 32.5 ° slope anchor ring with vertical sagittal plane; After capping and cylindrical shell grafting, 32.5 ° slope anchor ring on 32.5 ° slope anchor ring in the capping and the cylindrical shell forms the dovetail groove that the anchor ring of 0.5mm is arranged at the bottom; Weld at the dovetail groove position again.
Effect of the present invention is:
Solder flux and scolder can go deep into the annular groove of circumferential weld inside, welding base ring face on the cylindrical shell is owing to there is a unsettled anchor ring, little molten bath is formed on during the welding gun sparking and dovetail groove bottom, and welding heat can not conduct, and concentrates on this unsettled anchor ring of cylindrical shell upper base anchor ring, heat does not run off, make this unsettled anchor ring can reach fusing fully, be welded together, make melting jail, the horizontal position of cylindrical shell with capping, reach the welding position thickness requirement, reach the sealing intensity requirement.

The specific embodiment
As shown in Figure 1, 2: a kind of circular-seam welding method, at first with capping 7 and the processing of cylindrical shell 8 grafting contacts site; The outer ring, seam position that contacts with cylindrical shell in capping on the anchor ring is that a circle is 32.5 ° slope anchor ring (seeing the position of the label 1 among Fig. 2) with vertical sagittal plane, and the axial cylindrical face root that joins at 32.5 ° radially slope anchor rings and axial cylindrical face is one to enclose wide 1.5mm, the scrobicular ring (seeing the position of the label 2 among Fig. 2) of 0.5mm deeply; The lower edge bottommost of the capping of cylindrical shell and insertion is the thick 0.3mm of a circle, the base ring limit of wide 0.5mm (seeing the position of the label 3 among Fig. 2), the lower edge of covering near the base ring banding is that a circle is 32.5 ° slope anchor ring (seeing the position of the label 4 among Fig. 2) with vertical sagittal plane; After capping and cylindrical shell grafting, 32.5 ° slope anchor ring on 32.5 ° slope anchor ring in the capping and the tube tank body forms the dovetail groove (seeing the position of the label 6 among Fig. 2) that the anchor ring (seeing the position of the label 5 among Fig. 2) of 0.5mm is arranged at the bottom.
Weld at the dovetail groove position again.Solder flux and scolder can go deep into the annular groove of circumferential weld inside, welding base ring face on the cylindrical shell is owing to there is a unsettled anchor ring, little molten bath is formed on during the welding gun sparking and dovetail groove bottom, and welding heat can not conduct, and concentrates on this unsettled anchor ring of cylindrical shell upper base anchor ring, heat does not run off, make this unsettled anchor ring can reach fusing fully, be welded together, make melting jail, the horizontal position of cylindrical shell with capping, reach the welding position thickness requirement, reach the sealing intensity requirement.
