Abstract
The invention discloses a special A101 stainless steel welding electrode for decoration, and belongs to the field of welding materials. The stainless steel welding electrode is specially used for a thin metal plate structure or cosmetic decoration welding, and is characterized in that the stainless steel welding electrode adopts the following welding electrode coating formula (by weight percentage): 48% of natural rutile, 5% of marble, 3% of fluorite, 15% of pyroxene, 10% of mica, 6% of chromium metal, 6% of electrolytic manganese, 1% of ferrotitanium, 0.7% of CMC (Carboxy Methylated Cellulose) and 0.8% of microcrystalline cellulose. Compared with the prior art, the stainless steel welding electrode has excellent welding performances, such as soft and smooth welding technology properties, stable electric arc, easiness in restarting, weak splash, good slag spreadability, easiness in deslagging, level and attractive weld ripple, no pore, high crack resistance and good all-position weldability, and is low in coating cost.
Description
Affiliated technical field
The present invention relates to a kind of A101 finishing special stainless steel welding rod, be applicable to all-position welding, is the stainless steel electrode that is exclusively used in thin metal plate structure or the weldering of capping decoration.
Background technology
Current, the required A101 welding rod in domestic and international market often replaces with A102, A102 commercially available prod specification is generally ￠ 2-￠ 5mm, mainly be applicable to the welding of the welding of thick structure of stainless steels such as OCr19Ni9, OCr19Ni11Ti and pressure vessel, and this series products still exist at present welding technological properties owe gentle smooth, have stomata sensitivity, crack sensitivity, deficiency such as the considerable influence of splashing weldment is attractive in appearance.
The domestic and international product of the same type of A101 stainless steel welding electrode is in the coating recipe design, often because basicity is on the low side, Si content in the deposited metal is higher, very easily cause weld porosity sensitiveness, crack sensitivity, aspects such as next fusing point at slag, viscosity, surface tension, flowability, wellability are also unsatisfactory, be difficult to satisfy the requirements at the higher level of all-position welding performance, this point becomes more important concerning fitting-out work.
Summary of the invention
In order to overcome the deficiency of domestic existing A101 stainless steel welding electrode, the invention provides a kind of A101 finishing special stainless steel welding rod, this A101 finishing special stainless steel welding rod is high TiO
2(24-48%) rutile type electrode of coating, welding technological properties is gentle smooth, arc stability, restarting easily, splash faint, the slag spreadability good, take off that slag is easy, smooth attractive in appearance, the pore-free of weld ripples, crack resistance are strong, be applicable to Thin Stainless Steel metal plate all-position weldings such as OCr19Ni9, OCr19Ni11Ti, welding current is for exchanging or straight polarity direct current, be to be exclusively used in the welding rod that thin metal plate structure or capping are decorated weldering, also can be used for the welding of stainless steel structure such as household electrical appliance, instrument and meter, food utensil, medicine equipment, light textile equipment or xenogenesis mother metal.
The present invention solves the technical scheme that its technical problem takes: by analysis and research welding technological properties and physical characteristic, through formula test repeatedly, the following chemical coating of welding electrode prescription of selected employing (weight proportion meter)---natural rutile 45-55, marble 5-6, fluorite 2-4, pyroxene 13-17, mica 9-11, crome metal 5-7, electrolytic manganese 5-7, ferrotianium 1-2, CMC0.6-0.8, microcrystalline cellulose 0.7-0.9.Be mixed into welding rod crust spice by proportioning, with addition of low viscous waterglass, being coated with shoe through electrode extrusion press is the welding rod base at H00Cr21Ni10 special-purpose steel core wire, and drying machine drying and shaping again is made for the welding rod of diameter 1.6mm, diameter 2.0mm, diameter 2.5mm specification.
The present invention adjusts and improves domestic and international A101 stainless steel welding electrode coating recipe and material selection, design new coating recipe, develop new cheap raw material and replace expensive rare earth fluoride, chromic carbide iron, chrome oxide green, artificial mica, bismuth oxide, ice crystal etc., not only improved A101 stainless steel welding electrode performance, and reduced the coating cost, have very outstanding economic benefit and social benefit.
The specific embodiment
The invention will be further described below in conjunction with specific embodiment.
The embodiment of the invention: A101 fits up special stainless steel welding rod raw material ratio (by weight): natural rutile 48, marble 5, fluorite 3, pyroxene 15, mica 10, crome metal 6, electrolytic manganese 6, ferrotianium 1, CMC0.7, microcrystalline cellulose 0.8.
Carry out proportioning according to last surface compositions, raw material are stirred as requested add suitable quantity of water glass again and stir, then the medicinal powder that stirs is coated with pressure by hydraulic press at H00Cr21Ni10 special stainless steel core, dry about 24 hours drying in the shade, after crossing check, can be made into the welding rod of diameter 1.6mm, diameter 2.0mm, diameter 2.5mm specification.
