Abstract
A high-temperature vacuum hard alloy welding method is characterized by including the steps of (1) surface treatment of welding faces, wherein one end of a hard alloy bar is grinded to form an angle of 15 degrees-25 degrees, and the welding end faces of two welded block materials are ground and polished to form mirror surfaces; (2) shaping treatment, wherein the welding faces are cleaned up through anhydrous alcohol and coated with an anaerobic adhesive, and then the two welding faces are bonded to be shaped; (3) vacuum welding, the shaped welded product is contained in a graphite boat and placed in a sintering area of a vacuum sintering furnace, and a welded opening is compressed through the gravity. The problem that an overlength and overlarge hard alloy is difficult to weld is solved in a bevel angle welding mode.
Description
Technical field:
The present invention relates to carbide alloy welding technology field, be specifically related to a kind of high temperature, vacuum carbide alloy welding method.
Background technology:
Along with scientific and technical development, the demand of carbide alloy is constantly had to new requirement.Especially in overlength super large carbide alloy demand, owing to being subject to the restriction of current general compacting, agglomerating plant, for example cannot produce overlength (hard alloy strip more than 1000mm): the hard alloy strip thin slice of the 1700mm * 22mm * 3mm producing now, can only weld with the rectangular of two 850mm; Super large (the above hard alloy blocks material of 50kg) is for example: the hard alloy blocks material of the long 200mm * wide 200mm * high 150mm producing now, can only be welded by two block length 200mm * wide 100mm * high 150mm, disposable compacting sintering cannot meet the market demand of current carbide alloy.
Summary of the invention:
The object of this invention is to provide a kind of high temperature, vacuum carbide alloy welding method, the mode that it welds by oblique angle, has solved overlength, super large carbide alloy welds difficult problem.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: its welding method is:
Step 1: the surface treatment of solder side
For hard alloy strip, weld: first the different thickness of root Ju goes out the angle of 15 °-25 ° in wherein one end grinding of two soldered carbide alloy bars, the welding end surface of two blocks of soldered piece material is polished, require flatness≤5 micron, be then polished to minute surface;
Step 2: heat treatment
Solder side is cleaned up with absolute alcohol, more a kind of anaerobic glue is coated on solder side surface, then two solders side are bonded together its sizing;
Step 3: vacuum welding
Welding product after sizing is installed in the sintering zone that is placed on vacuum sintering furnace with graphite boat, and by soldering opening gravitational compaction.Then according to different Hard alloys at 1380 ℃--select a temperature spot to carry out high-temperature vacuum welding for 1420 ℃, then according to product individual hour of the insulation 1-2 that varies in size after arriving welding temperature point.
The present invention has following beneficial effect: the mode that it welds by oblique angle, has solved overlength, super large carbide alloy welds difficult problem.

For hard alloy strip, weld: first the different thickness of root Ju goes out the angle of 15 °-25 ° in wherein one end grinding of two soldered carbide alloy bars, the welding end surface of two blocks of soldered piece material is polished, require flatness≤5 micron, be then polished to minute surface;
Step 2: heat treatment
Solder side is cleaned up with absolute alcohol, more a kind of anaerobic glue is coated on solder side surface, then two solders side are bonded together its sizing;
Step 3: vacuum welding
Welding product after sizing is installed in the sintering zone that is placed on vacuum sintering furnace with graphite boat, and by soldering opening gravitational compaction.Then according to different Hard alloys at 1380 ℃--select a temperature spot to carry out high-temperature vacuum welding for 1420 ℃, then according to product individual hour of the insulation 1-2 that varies in size after arriving welding temperature point.
This specific embodiment has following beneficial effect: the mode that it welds by oblique angle, has solved overlength, super large carbide alloy welds difficult problem.
