Abstract
The invention relates to a method of a welding technology, in particular to a pressure welding technology. In a quality inspection process of the conventional double-bottom kitchenware adopting pressure welding, product deformation or cracking appears easily, the yield of a product is reduced substantially and the cost is increased, and the product can not be promoted to the foreign market easily if the product can not meet the standards of the foreign market. The pressure welding technology comprises the following processing steps: Step one: a welding part of a welding object is cleaned; Step two, the welding object is subjected to the pressure welding along the welding part by using a welding flux, wherein in the step of cleaning, sandblasting or grinding treatment on the welding part is carried out, and the surface roughness of the welding part after the sandblasting or grinding treatment is Ra3.5-12.0. The quality of the product is improved greatly, the welding requirements on the double-bottom kitchenware or stainless steel double-bottom kitchenware from the domestic and foreign markets can be met, the foreign market is opened, the market competitiveness of the domestic product is improved, and the use safety of consumers is guaranteed.
Description
Technical field
The present invention relates to a kind of method of welding procedure, refers in particular to a kind of bond technology.
Background technology
The multiple bottom kitchen utensils of existing some aluminum components or stainless steel part when being welded, before basic welding is met
Put, simply simply clean, then carry out pressure welding, and domestic multiple bottom Industry code requirements pressure welding product is in dry combustion method to 200 DEG C
Afterwards, cool down in the water that the product after dry combustion method is put into 20 DEG C, repeatedly 50 indeformable not cracking persons are qualified, and European Union is to multiple bottom
Pressure welding product requirement, product dry combustion method to 400 DEG C puts into product in 20 DEG C of water, does 20 times, and pressure welding is multiple, and bottom is indeformable does not ftracture
Person is qualified.And deformation of products or cracking occur in quality check process, easily in the multiple bottom kitchen utensils of existing employing pressure welding, greatly
The qualification rate of product is reduced greatly, increases cost, meanwhile, when foreign market standard cannot be met, then it is difficult to push to product
Foreign market.
The content of the invention
First, the technical problem to be solved
The purpose of the present invention be for the problems referred to above existing for prior art, spy provide a kind of technical operation difficulty compared with
It is low, can effectively improve the bond technology of product pressure welding performance.
2nd, technical scheme
To solve above-mentioned technical problem, bond technology of the present invention, its processing step is included：
Step one：The step of weld to welding thing is cleared up；
Step 2：Pressure welding is carried out using solder along weld by thing is welded；
Wherein, the step of above-mentioned cleaning includes the process that sandblasting or polishing are carried out to weld, Jing sandblastings or beats
The surface roughness of the weld after the process of mill is Ra3.5～12.0.
Used as optimization, above-mentioned solder is formed by solder flux, solder and water proportioning, above-mentioned solder flux, the weight between solder and water
Than for 1.3～1.5:1:0.57～0.75.
3rd, beneficial effects of the present invention
The present invention to weld thing carry out sandblasting or grinding process when, by welding thing on weld oxide and its
He removes impurity, exposes the body of welding thing, and then solder side is polished according to the roughness requirements of setting, finally completes
Pressure welding is welded；Jing repetition tests gained, by product obtained in said method, can be put into 20 DEG C in dry combustion method to after 440 DEG C
Water in cool down, pressure welding is multiple, and bottom is indeformable does not ftracture, and the requirement of product is welded to multiple base pressure well beyond European Union；Improving product matter
While amount, foreign market is opened, improve itself competitiveness of product in market；Meanwhile, ensured consumer uses safety.
Claims (2)
