Description
Technical field
The invention mainly relates to office equipment technical field, more particularly to a kind of stainless steel weldering for manufacturing office equipment
Item.
Background technology
Welding rod is made of core wire and coating two parts.Welding rod is outside metal core wire by coating（Coating）Uniformly, centripetally
Extrusion is on core wire.Welding rod type is different, and core wire is also different.The metal core of core wire, that is, welding rod, in order to ensure the quality of weld seam with
Performance has the content of each metallic element in core wire stringent regulation, especially to objectionable impurities（Such as sulphur, phosphorus) contain
Amount, should there is stringent limitation, be better than base material.
Stainless steel electrode refers to being coated with a kind of welding rod expected as source using stainless steel, can be divided into straight-chromiun stainless steel welding rod and chromium nickel not
Become rusty steel electrode, is widely used in the industries such as chemical industry, chemical fertilizer, oil, medical machinery manufacture.

Rutile：Oxidisability is weaker, and the hot removability of slag is good, arc stability, and molten bath is tranquil, can refine transition molten drop, beautifies weld seam
Forming, anti-gas porosity are good；
Potassium carbonate, barium carbonate：Main function is slag making and gas making, when carbonate content is relatively low, the gas making of coating and slag making energy
Power declines, and is reduced to the protective effect of weld seam, causes the decline of weld properties；If the too high levels of carbonate, coating
Gas making amount is excessive, and arc stability declines, and splashes and increases, and appearance of weld is coarse, therefore the content control of carbonate exists in the present invention
15~35%；
Calcium carbonate：Main function is plasticity, elasticity and the mobility for improving coating paint during welding rod extrusion, improves welding rod
Extrusion quality, keep electrode coating surface smooth without crack；
Titanium dioxide：Main function makes stabilising arc, keeps molten bath tranquil, few to splash, conductive, is easy to operate, can form short slag, right
Yu Li, overhead welding have remarkable result, can generate active slag, and uniform fold protects weld seam on solder, take off slag conveniently, crystallization speed
Degree is fast, keeps weld ripples careful；
Molybdenum-iron：Corrosion resistance can be effectively improved, is added primarily as alloying constituent, ensures weld seam corrosion resistance；
Manganese powder, chromium powder：Main function is Transition-metal Alloys, ensures alloy element component in weld seam, it is ensured that the corrosion resistance of weld seam is same
Shi Tigao weld strengths；
Magnesium powder：The oxygen content in weld seam is reduced, ensures to be not easy to be aoxidized when welding；
Ice crystal：The surface tension that liquid metal can be reduced reduces the fusing point of slag, improves the mobility of slag, reduces stomata shape
At probability, improve the mouldability of weld seam；
Binder uses potassium-sodium water glass, can play the role of stabilising arc.
Welding rod of the present invention arc stability in welding, splashes few, and appearance of weld is good, takes off slag and is easy, welding rod operating characteristics is excellent
It is different；The present invention improves the oxidative resistance and corrosivity of welding rod by the way that the Ultra-low carbons wldings such as Gao Ge, nickel, molybdenum and niobium are added.
