Abstract
The invention discloses a welding process of thousand pure platinum ornaments, which is characterized by comprising the following steps of: horizontally placing two or more thousand pure platinum jewelry semi-finished products to be welded and aligning welding parts in the working environment with the temperature of 16-26 DEG C and the humidity of not more than 65 percent, and melting the welding parts of the thousand pure platinum jewelry semi-finished products by adopting the outer flame of a welding flame with the temperature of 1773+/-5 DEG C to realize rapid fusion and welding, wherein the weld forming coefficient is 0.9-1.1. The welding process is adopted, thereby effectively ensuring the purity and the attractive surface of jewelries, being beneficial to energy saving and consumption reduction and improving the production efficiency.
Description
Technical field
The present invention relates to a kind of processing technology of platinum jewellery, especially relate to a kind of welding process of thousand pure platinum ornaments.
Background technology
So-called thousand sufficient platinum jewellery are meant that platinum jewellery finished product quality meets or exceeds 99.9% jewellery.Traditionally, people are in sufficient platinum jewellery processing, adopt the mode of use welding agent or welding rod to weld to the welding of jewellery more, carry out the welding of jewellery and adopt with upper type, form big solder joint easily, the processing that is not easy to subsequent handling is handled, production efficiency is low, and not attractive in appearance, especially adopt when carrying out the welding of jewellery because there are difference in the composition and the sufficient platinum jewellery of welding powder or welding rod with upper type, this also can reduce the composition of sufficient platinum jewellery, this phenomenon,, particularly evident for quality in the thousand sufficient platinum jewellery processing more than 99.9%, influenced the quality of thousand sufficient platinum jewellery and attractive in appearance.Therefore, just need provide a kind of welding quality and energy-saving and cost-reducing welding process of thousand pure platinum ornaments of improving.
Summary of the invention
Technical problem to be solved by this invention has provided a kind of welding quality and energy-saving and cost-reducing welding process of thousand pure platinum ornaments of improving.
In order to solve above technical problem, the technical solution adopted in the present invention is: a kind of welding process of thousand pure platinum ornaments, its key: adopt under the working environment of 16 ℃～26 ℃ of temperature, humidity≤65%, the thousand sufficient platinum jewellery semi-finished product more than two or two of needs welding are set level and welding portion is alignd, the flame envelope that adopts 1773 ± 5 ℃ of weldering flames is with the half-finished weld fusing of thousand sufficient platinum jewellery, realize rapid welding welding, and aspect ratio of weld is between 0.9～1.1.The control of the working environment when wherein the control of working environment is meant welding in the operating room, the control of its temperature and humidity also can suitably be adjusted according to practical condition.
Improvement as preferred version of the present invention, weld the flame that flame adopts the hydrogen-oxygen welding gun, employing at the uniform velocity is burned to 1773 ± 5 ℃ mode with the flame of hydrogen-oxygen welding gun, and adjusts weld heat input and remain between 220～240J/cm, takes welding method from left to right.
As the further improvement of preferred version of the present invention, when welding, weld flame and move with 1.2cm/s speed, to realize welding portion evenly the being heated raising welding quality along the welding portion trend.
Further improvement as preferred version of the present invention, thousand sufficient platinum raw materials employing gold contents are 99.99% platinum, and this thousand sufficient platinum raw material in use adopts wrapping paper to isolate to ensure quality, all must keep clean to the equipment in the described technique for welding process, does not have other any impurity.
As further improving again of preferred version of the present invention, thousand sufficient platinum jewellery after the welding need carry out surface treatment again, so that jewellery surface aesthetic, surface-treated equipment mainly contains polishing machine, pattern-etching machine, mill and makes machine etc., at first carrying out polishing makes the jewellery surface produce gloss, adopt the pattern-etching machine device to go out various decorative patterns then, with the concentrated sulfuric acid decontamination or impurity processing are carried out in the jewellery surface more afterwards, at last jewellery are ground to beat and handle at jewellery surface car.
Adopt above technical scheme, make the present invention improve welding quality by welding procedure at thousand pure platinum ornaments, guarantee constant, the surperficial no big solder joint of thousand pure platinum ornaments quality, smooth surface, attractive in appearance after the welding, subsequent technique is simpler, whole welding procedure heat input remains between 220～240J/cm, more energy-saving and cost-reducing, and improved production efficiency.
The specific embodiment
Employing is under the working environment of 16 ℃～26 ℃ of temperature, humidity≤65%, the thousand sufficient platinum jewellery semi-finished product more than two or two of needs welding are set level and welding portion is alignd, the flame envelope that adopts 1773 ± 5 ℃ of weldering flames is with the half-finished weld fusing of thousand sufficient platinum jewellery, realize rapid welding welding, and aspect ratio of weld is between 0.9～1.1.The control of the working environment when wherein the control of working environment is meant welding in the operating room, the control of its temperature and humidity also can suitably be adjusted according to practical condition.
Weld the flame that flame adopts the hydrogen-oxygen welding gun, adopt the flame of hydrogen-oxygen welding gun at the uniform velocity is burned to 1773 ± 5 ℃ mode, and adjust weld heat input and remain between 220～240J/cm, take welding method from left to right.
When welding, weld flame and move with 1.2cm/s speed, to realize welding portion evenly the being heated raising welding quality along the welding portion trend.
It is 99.99% platinum that thousand sufficient platinum raw materials adopt gold contents, and this thousand sufficient platinum raw material in use adopts wrapping paper to isolate to ensure quality, all must keep clean to the equipment in the described technique for welding process, does not have other any impurity.
Thousand sufficient platinum jewellery after the welding need carry out surface treatment again, so that jewellery surface aesthetic, surface-treated equipment mainly contains polishing machine, pattern-etching machine, mill and makes machine etc., at first carrying out polishing makes the jewellery surface produce gloss, adopt the pattern-etching machine device to go out various decorative patterns then at jewellery surface car, with the concentrated sulfuric acid decontamination or impurity processing are carried out in the jewellery surface more afterwards, at last jewellery are ground to beat and handle.
