Abstract
The utility model relates to a protective coating for welded seams of stainless steel water tanks. The utility model is characterized in that the surface of a welded seam in a stainless steel water tank is welded with a layer of metal alloy welding flux which can contains tin, lead, zinc, silver, and analogous metal. The utility model has the advantages of good chemical stability and good corrosion resistance. The utility model also has the advantage that the crystal lattice corrosion to welded seams by water can be effectively blocked, so that the service life of the stainless steel water tank can be prolonged.
Description
The utility model relates to the weldering of stainless steel water tank and meets protection.
Known stainless steel water tank adopts high-frequency welding [roll welding] or argon arc welding procedure to weld water tank usually, its weldering is met and is not done any processing, but stainless steel was once after being welded by high-frequency welding [roll welding] or argon arc welding procedure, the weldering of soldered mistake meets the physics crystalline phase tissue that material itself will take place to change, its corrosion resistance of material after this generation physics crystalline phase changes just is nothing like stainless steel itself, will the lattice corrosion phenomenon take place at the weldering place of meeting, influence the stainless steel water tank maximum hidden danger place in service life so this weldering is met just to become.
The purpose of this utility model is that the weldering that proposes a kind of stainless steel water tank meets protective finish, comes effectively to overcome really the defective that above-mentioned stainless steel water tank weldering is met.
The utility model is to realize by following technical scheme, weldering in the stainless steel water tank that cleans up meets weldering firm on the surface to scribble the layer of metal solder, this metal alloy scolder can be a stanniferous, plumbous, zinc, metals such as silver, its ratio is that the content of tin is greater than 50%, plumbous content is less than 50%, the content of silver is greater than 0.1%, the content of zinc is greater than 0.01%, have preferable chemical stability and corrosion resistance preferably, can very effective blocking-up water to stainless steel weldering meet the lattice corrosion that is produced, thereby the service life of improving stainless steel water tank greatly.
Further specify the utility model below in conjunction with accompanying drawing 1.
Fig. 1, the weldering in stainless steel water tank 1 is met to weld on 2 and is scribbled layer of metal solder 3.
Claims (3)
1, protective finish is met in stainless steel water tank weldering, it is characterized by weldering stainless steel water tank 1 in and meets to weld on 2 and scribble layer of metal solder 3.
2, protective finish is met in stainless steel water tank weldering according to claim 1, it is characterized by metals such as metal alloy scolder 3 stanniferous, lead, silver, zinc; its ratio is that the content of tin is greater than 50%; plumbous content is less than 50%, and the content of silver is greater than 0.1%, and the content of zinc is greater than 0.01%.
3, protective finish is met in stainless steel water tank according to claim 2 weldering, it is characterized by metals such as metal alloy scolder 3 stanniferous, lead, its ratio be the content of tin greater than 50%, plumbous content is less than 50%.
