Abstract
The invention discloses a method for welding gold jewellery, which comprises the following steps: parts requiring joint by welding of two or more semi-manufactured jewellery workpieces needing joint are aligned, welding set flame is adopted for preheating, glowing, melting and welding the parts requiring joint so as to ensure that the two or more semi-manufactured jewellery workpieces are naturally welded as a whole. The method does not require the adding of any auxiliary welding agent and has simple post-treatment procedures without any environmental pollution. Furthermore, the welding product has stable structure and the color never changes.
Description
Technical field
The present invention relates to a kind of processing method of gold ornament, especially relate to the welding method in the gold ornament processing.
Background technology
When people carry out welding processing in the gold ornament process at present, use assisted welding agent more, employing is used welding powder in the half-finished welding position of ornaments, by the fusion welding powder ornaments semi-finished product are connected, as hollow kwan-yin, Buddhist, the lock bag waits the welding of the hollow ornaments of oil pressure class, employing is 75% low quality welding rod about being at the inboard additive colors of hollow goods, and be stained with a certain amount of quality at ornaments semi-finished product joint is the 85%-95% welding powder, aim at joint with flame then and burn the red welding powder fusion weld that makes, and for the half-finished welding of manual chain class ornaments of adopting casting casting mode to be processed into, then directly adopt welding powder on interface point, make the welding powder fusion weld.Because the fusing point of welding agent is low, generally between the 600-800 degree, and the gold fusing point is 1064 ℃, if temperature control is improper, welding agent is run out of interface easily, usually said " race weldering " that Here it is, therefore wayward, especially welding rod, welding powder must use with the scaling powder borax, and after the welding ornaments use welding agent, must handle surface of the work and inner borax of entering with hydrochloric acid after the heating and nitric acid, not only handle loaded down with trivial details and also heating process in form acid mist easily, atmosphere is produced pollution, influence the healthy of operator.Because welding agent mostly is furnished with other metallic elements such as a certain amount of copper, silver, zinc, make the deepening of gold ornament joint color and luster easily simultaneously, it is attractive in appearance to influence product.
Summary of the invention
Technical problem to be solved by this invention has provided and a kind ofly need not to dose any auxiliary welding agent, postprocessing working procedures and simply do not have any environmental pollution and welding product Stability Analysis of Structures, will never change colour gold ornamental article welding method.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of gold ornamental article welding method, gold ornament semi-finished product workpiece is needed the position alignment of solder joints, adjust soldering set flame preheating is carried out in ornaments semi-finished product workpiece junction, the workpiece entire body is burnt to taking on a red color, afterwards soldering set flame is pressed ornaments semi-finished product workpiece junction tendency direction, rocked flame heat ornaments semi-finished product workpiece junction fusion weld.Concrete, adopt a kind of in following two kinds of operations:
1) gold ornament semi-finished product workpiece is needed the position of solder joints align;
2) adjust soldering set flame and be thin blue flame, temperature reaches 1000 ℃～1100 ℃;
3) use soldering set flame ornaments semi-finished product workpiece junction preheating 0.3～6 second, the workpiece entire body is burnt to taking on a red color;
4) soldering set flame is pressed ornaments semi-finished product workpiece junction tendency direction, rocked flame 0.4 second～3 seconds, with ornaments semi-finished product workpiece junction fusion weld, welding one by one then.
Pass to step like this, to need to engage ornaments semi-finished product workpiece is matrix, adopt that soldering set flame needs that attachment are red by preheating, burning, fusing, welding process, make ornaments semi-finished product workpiece integrally welded naturally, whole process need not to dose any auxiliary scolder, the flame that soldering set flame can adopt oxygen welding gun, water welding gun to produce, flame temperature height, the flame envelope forming, easy to control.In the welding, the ornaments semi-finished product workpiece that needs to engage can be two or more;
For the oil pressure class ornaments that adopt the processing of mould and oil pressure unit such as the welding of hollow ornaments, adopt following steps:
1) adopts oil pressure and Mould Machining to make each semi-finished product workpiece of gold ornament, two or two above gold ornament semi-finished product workpiece are needed the position alignment of solder joints; As hollow kwan-yin, Buddhist, lock bag etc., adopt positive and negative two face binding sites alignment;
2) oxygen welding gun pressure is transferred to 0.2Mpa～1.5Mpa, rifle mouth flame is transferred carefully, adjust soldering set flame and be thin blue flame, temperature reaches 1000 ℃～1100 ℃;
3) use oxygen welding gun flame ornaments semi-finished product workpiece junction preheating 1～6 second, the workpiece entire body is taken on a red color, to reach the gold fusing point;
4) oxygen welding gun flame is pressed ornaments semi-finished product workpiece junction tendency direction, rocked flame 0.4 second～1.8 seconds, with ornaments semi-finished product workpiece junction fusion weld, welding one by one then.
And, can adopt following steps for the ornaments that adopt the processing of casting casting processing mode such as the welding of chain class ornaments:
1) adopts casting casting processing mode to make each semi-finished product workpiece of gold ornament, two or two above gold ornament semi-finished product workpiece are needed the position alignment of solder joints; As manual chain semi-finished product workpiece, each cuff link workpiece of manual chain connected set and the position alignment of solder joints;
2) water welding gun pressure is transferred to 0.2Mpa～1.5Mpa, adjust soldering set flame and be thin blue flame, temperature reaches 1000 ℃～1100 ℃; The characteristics of water welding gun are the high temperature slow fire, and flame temperature can reach 2300 degree, and the welding quality height is safe in utilization, the control of anti-backfire, automatic pressure are housed, air pressure is reported to the police and automatic safety device automatically, and free from environmental pollution, firing right thing is water, does not have other waste gas and produces;
3) water welding gun flame takes on a red color the workpiece entire body ornaments semi-finished product workpiece junction preheating 0.3～6 second;
4) water welding gun flame is pressed ornaments semi-finished product workpiece junction tendency direction, rocked flame 0.4 second～3 seconds, with ornaments semi-finished product workpiece junction fusion weld, welding one by one then.
The raw material of the preparation gold ornament semi-finished product workpiece that preferably, adopts among the present invention can adopt the Au999-Au9999 after purifying.Certainly raw material also can adopt the gold of other quality, and also can adopt silver (Ag), platinum (Pt) to wait other precious metal raw material, just when welding, this welding method is suitably adjusted and got final product according to the different characteristic of each raw material, this is the general knowledge of knowing concerning those skilled in the art.
Adopt welding method of the present invention, need not to dose any auxiliary scolder, saved resource; make that postprocessing working procedures is simple and do not have any environmental pollution, effectively protected that the operator's is healthy; and kept product initial quality content, Stability Analysis of Structures, the welding position is will never change colour.
