Abstract
The invention discloses a tool welding technology. The tool welding technology includes the following steps that 1, a welding material is dried for 2 hours at the temperature of 200 DEG C and placed into an insulation barrel; 2, rust, oil stains and other impurities on the surface of base metal are cleared away through acetone; 3, the welding material is welded to the base metal through an electric welding machine in a bead weld manner, and bead weld is carried out in a short arc welding manner; 4, a welded product is placed at the temperature of 600 DEG C to 700 DEG C for 1-2 hours and then cooled slowly in a furnace; and 5, the cooled product is taken out, the surface of a bead weld layer is cleaned, PT inspection is carried out, and welding repair and hammering are carried out if defective portions are founded. By means of the tool welding technology, the welding steps can be simplified, welding efficiency is improved, and machining and manufacturing of large tools are finished.
Description
Technical field
The present invention relates to field of machining, particularly relate to a kind of Welding of cutters technique.
Background technology
Different welding methods has different welding procedures.Welding procedure is mainly according to material, the trade mark, the chemical composition of welded piece, and weldment structure type, welding performance requires to determine.First will determine welding method, as manual metal-arc welding, submerged-arc welding, argon tungsten-arc welding, gas metal-arc welding etc., the kind of welding method is very many, can only select as the case may be.After determining welding method, reenact welding condition, the kind of welding condition is different, as manual metal-arc welding mainly comprises: welding rod model (or trade mark), diameter, electric current, voltage, source of welding current kind, polarity connection, the welding number of plies, number of channels, the method for inspection etc.But, due to the diversity of welding manner and welding material, there is various abnormal activity in welding process, and then cause the quality of welding work pieces lower, sometimes also there will be accident.
Existing cutter is that body is less mostly, blade negligible amounts, manufactures this cutter and leads to machine in normal service and cut mother metal, polished, seldom use the mode of welding to carry out, and build is comparatively large, and the more cutter of blade cannot manufacture with existing machine.
Because above-mentioned defect, the design people, actively in addition research and innovation, to founding a kind of Welding of cutters technique, make it have more value in industry.
Summary of the invention
For solving the problems of the technologies described above, the object of this invention is to provide one can simplify welding step, improves welding efficiency, completes the Welding of cutters technique of large-scale cutter manufacture.
A kind of Welding of cutters technique that the present invention proposes, is characterized in that: comprise the following steps:
Step one: wlding is dried 2 hours under 200 DEG C of environment, is then positioned in heat-preserving container;
Step 2: the impurity such as the iron rust on mother metal surface, greasy dirt are removed clean with acetone;
Step 3: be welded on mother metal by wlding heap with electric welding machine, carries out built-up welding by the mode of short arc welding;
Step 4: the product after having welded is incubated 1-2 hour under 600 DEG C of-700 DEG C of environment, then Slow cooling in a furnace;
Step 5: taken out by cooled product, clear up overlay surface, then does PT inspection, if find that there is fault location, then carries out repair welding process and hammering.
As the further improvement of the inventive method, the material described in step one is Ken Nasitaili (STELLITE6) Co Cr W Alloy Surfacing welding rod.
As the further improvement of the inventive method, the material described in step 2 is 45# steel.
