Abstract
The invention relates to a large-size target welding method, comprising steps of: step 1, preheating a target and a backboard, step 2, metalizing the target and the backboard; step 3, manufacturing a solder layer and arranging a gap line; step 4, covering the target; step 5, regulating the position of the target and pressing; step 6, naturally cooling to room temperature to finish the welding, wherein the preheating temperature in step 1 is controlled at 200 DEG C; the metallization temperature for the target and the backboard in step 2 is controlled at 185-195 DEG C; the gap line in step 4 is 0.3mm; and the exerted force in step 5 is 500kg. A large-size aluminum target manufactured by the large-size target welding method is low in porosity and few in defects, saves cost and is more beneficial to practical use.
Description
Technical field
The present invention relates to a kind of Al target preparation method, particularly relate to a kind of large-scale Al target welding and connect method.
Background technology
Nearly all welding method all is to be used for aluminium and aluminium alloy, but makes aluminium and aluminium alloy welding poor-performing, in welding process, tends to produce dissimilar weld defects and is retained in the weld seam, like pore and crackle etc.Weld porosity and crack defect account for 40%～50% of welding waste product sum, cause the significant wastage of material.
Because the defective that above-mentioned existing aluminium target welding connection technology exists, the design people actively studies innovation, connects method in the hope of founding a kind of novel large aluminium target welding, makes it have more practicality.
Summary of the invention
Main purpose of the present invention is, overcomes existing aluminium target welding and connects the defective that method exists, and provide a kind of new large-scale aluminium target welding to connect method, and technical problem to be solved is through the concrete operations of improvement welding process, and it is few to obtain hole, the welding of aluminum target that crackle is shallow.
The present invention compared with prior art has tangible advantage and beneficial effect.For reaching the object of the invention, technology contents is following:
A kind of large-scale target welding method comprises the steps:
Step 1 is carried out preheating with target and backboard;
Step 2 is with target and backboard metallization;
Step 3 is made solder layer, places the gap line;
Step 4 is to the target lid;
Step 5, suitably exert pressure in adjustment target position;
Step 6 naturally cools to room temperature, accomplishes welding;
Preheat temperature is 200 ℃ in the abovementioned steps 1;
Aforementioned target and backboard metallizing temperature are 190 ± 5 ℃;
In the abovementioned steps 4, the gap line is 0.3mm;
The external force that applies is 500kg in the abovementioned steps 5.
By technique scheme, large-scale aluminium target welding according to the invention connects method and has advantage at least:
Through before the welding backboard and target being carried out the defective that preheating reduces finished product; Welding process has reduced the finished product hole to target and backboard metalized, obtains the high-quality Al target.
Above-mentioned explanation only is the general introduction of technical scheme of the present invention, understands technological means of the present invention in order can more to know, and can implement according to the content of specification, below with preferred embodiment of the present invention and conjunction with figs. specify as after.
