Abstract
The invention provides a wetting agent special for welding electrodes. The wetting agent can be universally used in various welding electrodes, especially A101, A102 and J422 electric welding coating formulas. The wetting agent is prepared by selecting and adopting the following raw materials according to a proportion, by weight, 25-30% of augite, 30-35% of potassium-rich augite and 38-42% of clotted augitite by means of high-temperature physical and chemical metallurgy. By the wetting agent special for the welding electrodes, surface tension of slag can be effectively lowered, wetting effect of the slag can be enhanced, a smooth-edge transition area can be promoted be formed between an edge of a welding line and a base material, quality indicators like cold bending, drawing and crack resistance of a welded joint can be directly improved, welding process performance can be effectively improved, and raw material and coating cost can be lowered.
Description
Affiliated technical field
The present invention relates to the special-purpose wetting agent of a kind of welding rod, belong to welding rod raw material field.
Background technology
Current, the welding rod manufacturing industry is being faced with and is improving the quality and reduce cost problem.The raising of all-position welding processing performance is still the difficult point of scientific research, no matter is general or special purpose welding rod, all requires the feel operation gentle smooth, and the cap weld moulding is attractive in appearance, and it is easy to take off slag, does not spatter to hinder the mother metal outward appearance.Appearance of weld U.S., except physical dimension will meet the standard, the most important thing is welding point---can weld edge and mother metal heat affected area form neither undercut, the intermediate zone mild attractive in appearance that does not have overlap again is because this intermediate zone directly has influence on clod wash, stretching, crack resistance index of welding point etc.The formation of intermediate zone attractive in appearance depend on liquid deposited metal and molten slag to the wetting action of solid base metals, and this wetting action depends primarily on Electroplating welding materials gently.
Summary of the invention
In order to improve welding rod product quality and reducing cost, through a large amount of research and experiments, the invention provides a kind of can be in multiple welding rod, particularly A101, A102, J422 electric welding coating recipe general special-purpose wetting agent of welding rod.This wetting agent can reduce the surface tension of slag effectively, strengthen the wetting action of slag, promote the intermediate zone that forms orle between weld edge and the mother metal (both to be difficult for undercut, be difficult for forming overlap again), directly improve the quality index such as clod wash, stretching, crack resistance of welding point, welding technological properties can not only be improved effectively, and raw material coating cost can be reduced.
The present invention solves the technical scheme that its technical problem takes: by domestic and international multiclass electrode coating and welding slag are furtherd investigate, grasp the rule of raw-material wetability and appearance of weld, utilize the method for high-temperature physics and chemical metallurgy, the following raw material ratio of selected employing (by weight): pyroxene 25-30, rich potassium pyroxene 30-35 coagulates pyroxenite 38-42, fully mixes by proportioning, through 180 ℃ of bakings 2-5 hour, cooling back damp-prrof packing was made the special-purpose wetting agent of welding rod.
The invention has the beneficial effects as follows: the cheap chemical coating of welding electrode new material with innovation characteristic---the special-purpose wetting agent of a kind of welding rod can replace or part replaces in the traditional electrical electrode coating raw material white clay, sepiolite clay, feldspar, mica and CMC, microcrystalline cellulose etc. add material, reduce the K in the potassium sodium mixing water glass
2The O content requirement, the welding rod that contains the special-purpose wetting agent of welding rod has good welding technological properties, and particularly blow force of arc is big, and is powerful tall and straight, molten drop is injection excessively, fly quick-fried carefully and lack, weld seam has outstanding metallic luster, and particularly weld fumes is few under the double action of optimum coating sleeve and optimum slag, the restarting performance is good, not only improve the welding rod performance, and reduced the coating cost, had 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:
The following raw material ratio of selected employing (by weight): pyroxene 28, rich potassium pyroxene 32 coagulates pyroxenite 40, fully mixes by proportioning, and through 180 ℃ of bakings 2-5 hour, cooling back damp-prrof packing was made the special-purpose wetting agent of welding rod.
Claims (1)
1. the special-purpose wetting agent of a welding rod is characterized in that: the following raw material ratio of selected employing (by weight): pyroxene 25-30, and rich potassium pyroxene 30-35 coagulates pyroxenite 38-42, fully mixes by proportioning, through 180 ℃ of bakings 2-5 hour, cooling back damp-prrof packing.
