Detailed Product Description: | Guangzhou Dasheng iron factory professional set design, production and operation of various types of iron casting, forging, punching, rolling, flower pieces campaign materials, iron furniture, wrought iron gates, wrought iron railings, anti-theft network and steel screen, and to undertake all kinds of cast iron, ductile parts production, but also took the design or to plans to sample custom. Cast iron welding repair method, it is manual arc, the main heat welding method, a semi-hot welding and cold welding method. Cold welding method that the whole is not greater than the temperature of cast iron welding repair method performed at 200 ℃. Find the crack in front of the crack at the end of 3 ~ 5mm hole drilled stop, according to the thickness take φ3 ~ 10mm. ② open groove mechanically beveling easy quality assurance. Open groove so as not to affect the accuracy of the principle of close, both divisible crack while ensuring strength. General should consider precision parts, wall thickness, load, rupture degree beveling mode selection. ③ generally used in welding nickel-based cast iron electrode, the electrode diameter the more detailed the better, should DC reverse cold welding. Weld long time, it is appropriate backward dispersed into short segments welding. ④ weld after welding attention to insulation slow cooling process, cast iron parts manufacturers, in order to avoid the formation of white phenomenon cooling too fast. Measures are: small parts can be hot ash covering the buried sand or heat, the four cast iron fittings, large parts you can use asbestos cloth cover, if promptly put back to Guangzhou Dasheng iron stove manufacturers better professional set design, production and operation of various types of cast iron , forging, punching, rolling, cast iron fittings customized, flower pieces campaign materials, iron furniture, wrought iron gates, wrought iron railings, anti-theft network and steel screen, and to undertake all kinds of cast iron, ductile parts production, but also took the design or plans sample custom. Industry Office because they can not repair the cracks of heavy cast iron replacement parts, causing huge economic losses. Apart electrodes quality reasons, the process is also an important factor in improper. The following process is based on the characteristics of a universal cast iron welding iron castings for heavy suggestion bug fixes. Of course, non-heavy cast iron also basically follow this process, but it is not so complicated. 1) roasted. Before welding, gas welding flame heating subparagraph (≤4000C) would cast iron water machine unit oil roasted to do, until not smoke so far. 2) crack arrest. At both ends of the crack does not crack at only 5mm diameter drill hole to prevent crack propagation. 3) beveling. Shovel to make defects, with the wheel or flat shovel open 70-900 beveling. Groove must penetrate cracks without leaving Chen Yu. Universal recommends using a universal 100 beveling electrodes, cast iron parts supply, which helps avoid mechanical beveling groove surface resulting in graphite aggregate form can not be processed when welding very hard iron carbide, commonly known as the white layer. Cast iron fittings customized, Guangzhou Dasheng iron (certified), the four cast iron fittings provided by Panyu District, Guangzhou City Shawan Tatsuo Structural Metal Products.
