Specific embodiment
In conjunction with the attached drawing phased array ultrasonic detection cross-drilled hole for being less than 6mm for stir friction welding seam thickness a kind of to the present invention
The design and production of reference block are described in detail:
Reference block is directed to the detection that stir friction welding seam thickness is less than 6mm.
Because cross-drilled hole can only be processed from end face, and probe scanning needs certain distance, so using several blocks of plates
Block connecting method is guaranteed.
The material selection of reference block material trademark identical with by part is examined.Process main plate 1, specification be 570mm ×
190mm.The long and wide size of reference block, based on the reserved reference block frame of automatic jig system after considering, Ke Yifang
It sets above.With a thickness of 1.8mm, 2.5mm, 3mm, 3.5mm, 4mm, 1 each 2 piece of the main plate of 5.0mm is shown in Fig. 1;
Then intermediate according to seeing that the docking mode of Fig. 2 is stirred friction welding (FW) welding by the identical 2 pieces of main plates 1 of thickness
For weld seam 2;
After the completion of welding, by each 30mm in part other than main 1 both ends weld seam of test block, 2 keyhole by machining excision, see
Fig. 3.At this moment 1 length of main plate is 510mm, the detection of weld seam 2 is carried out using detection method of X-ray, according to X-ray detection mark
Standard, to guarantee that 2 internal soundness of weld seam, welding quality should meet the regulation of file;
As shown in figure 4, processing cross-drilled hole 3 at 2 both ends of weld seam;The artificial defect processing dimension of cross-drilled hole 3 is shown in Table in reference block
1;
The processing dimension table of 1 reference block cross-drilled hole artificial defect of table
Unit is all mm;All long hole depth allowable errors of pore are not more than 0.05mm, remaining is having a size of free tolerance.
As shown in figure 5, two pieces of auxiliary plates 4 of processing;
As shown in fig. 6, two pieces of auxiliary plates 4 of Fig. 5 are fixed tightly in 1 two sides of Fig. 4 main plate, it is placed on later dedicated to having a competition
In block frame, facilitate detection.
Scanning mode of the phased array supersonic probe in reference block is shown in Fig. 7.
Manual inspection by phased array detection device, for inside stir friction welding seam and surface and near surface flaw
It surveys, and automatic detection can be taken into account.The reference block should be able to realize to the manual of certain type machine part stir friction welding seam and
Automate scanning.
The invention belongs to the reference blocks that phased array ultrasonic detection uses, and in particular to one kind is examined for ultrasonic phased array
Thickness Measurement by Microwave is less than the cross-drilled hole reference block of 6mm weld seam.The present invention overcomes the deficiencies of original ray detection method, using ultrasonic wave
Phased array detection method.
The present invention provides a kind of phased array ultrasonic detection cross-drilled holes pair for being exclusively used in stir friction welding seam thickness and being less than 6mm
Than test block, the tunnel type defect in stirring friction welding seam is simulated in test block.Because cross-drilled hole can only be processed from end face, and be popped one's head in
Scanning has certain distance again, so being guaranteed using several pieces of board material splice modes.
Every kind of thickness processes a group aluminum alloy agitating friction and welds test block, according to X-ray detection standard, to guarantee inside weld seam
Quality simulates the tunnel type defect in stirring friction welding seam, the cross-drilled hole type of working depth, size and position not etc. in test block
Artificial defect.Ultrasonic phased array probe carries out scanning in reference block.
It is described easy to operate, the time can be effectively saved, improve production capacity, there is larger practical application value.
