Description
Technical field
The present invention relates to a kind of agitating friction welding method, in particular to it is a kind of by aluminium alloy thick plate edge rolling at shell
Afterwards, the method that abutment joint is stirred friction welding to its longitudinal direction.
Background technique
Agitating friction weldering is a kind of according to the molding bond technology of metal plastic flowing, and welding temperature is lower than base material fusing temperature
Degree, heat input is low, and welding stress is small, and weld seam post welding distortion can be made to be effectively controlled；But before this duct butt-welding method butt welding
There are strict requirements in fit-up gap: it is required that weld seam butt-joint clearance is less than or is equal to 0.3 millimeter, weld seam is in a thickness direction
Misalignment is within 0.3 millimeter, and the misalignment of weld seam in the longitudinal direction is within 0.3 millimeter, position inner circle to be welded and inner circle backing plate
Between gap within 0.2 millimeter.Thickness is at 20 millimeters or more, and the aluminium alloy thick plate that yield strength is big, and edge rolling is at cylinder
Afterwards, when being welded to the longitudinal seam of docking, it may appear that two welding surfaces at butt weld are in the shape of the letter V docking, while
In edge rolling, welding end surface has the appearance of straight flange phenomenon, is unable to satisfy the requirement of weld gap before agitating friction weldering butt welding.In addition, stirring
When mixing friction welding (FW) progress aluminium alloy thick plate welding, when stirring-head underthrust speed matches improper with its revolving speed, weldering is also resulted in
The phenomenon that it is insufficient to connect starting point metal plastic flowing, causes stirring-head underthrust depth can not be in place, causes the back of weld seam weak
Binding deficient.
Summary of the invention
The present invention provides the positioning and welding method of a kind of longitudinal abutment joint of aluminium alloy thick plate edge rolling shell, solve
The technical issues of how agitating friction weldering being implemented to longitudinal abutment joint of aluminium alloy thick plate edge rolling shell.
The present invention is to solve the above technical problem by the following technical programs:
A kind of positioning and welding method of longitudinal abutment joint of aluminium alloy thick plate edge rolling shell, comprising the following steps:
One piece of first step, blanking rectangle aluminium alloy plate, plate thickness are 20-35 millimeters, and the length of the rectangle aluminium alloy plate is big
Aluminium is marked in the left and right ends of rectangle aluminium alloy plate according to the perimeter of pre-roll round casing in the perimeter of pre-roll round casing
The vertical lines of two pairs of position while weldings after alloy sheets edge rolling marks, make vertical line mark between the side of rectangle aluminium alloy plate there are
Pre- cutting edge surplus；
Second step, on four-roller furling plate round machine, by rectangle aluminium alloy plate, edge rolling is at cylindrical shell along its length, and by cylinder
Two butt joint edges of shape shell are spot-welded together；
Third step, in the cylindrical shell body below two butt joint edge spotwelds, along the direction vertical with spotweld, equally spaced weld
A row is met to lacing wire；
4th step, boring and milling fall spotweld at docking, to achieve the purpose that discharge stress；
5th step, the vertical line mark on the rectangle aluminium alloy plate that the first step marks, by vertical line mark and rectangle aluminium alloy
Between the side of plate there are pre- cutting edge surplus boring and milling fall, and make boring and milling go out two docking the faces of weld it is parallel to each other；
Then 6th step, the row for removing third step welding carry out second of edge rolling to cylindrical shell to lacing wire；
The cylindrical shell of secondary edge rolling is assemblied within agitating friction mounted welder by the 7th step, by the 5th step boring and milling go out that
This parallel two butt welding faces docking is pressed together；
8th step welds the two docking faces of weld by the way of agitating friction weldering: in welding, the depth of stirring-head underthrust
0.2 millimeter is added for the plate thickness of aluminium alloy plate, the speed of stirring-head underthrust is 0.15 millimeter per second, and the revolving speed of stirring-head is every
220 turns of minute, the lower pressure of stirring-head are thousand Ns of 35-55.
The present invention overcomes after aluminium alloy thick plate edge rolling, welding surface is V-shaped, and there are straight flanges, are not able to satisfy agitating friction
The requirement to weld seam is welded, the mutual cooperation of each process is passed through, it is ensured that appearance of weld is good, and weldquality is high, and welds
Connector tensile strength without any after welding treatment can reach the 70% of base material tensile strength.
