Characteristics of if bend pipe（1-5）

　　1 if the frequency of the use of vertical and external characteristics of the power supply, DC, the use of positive polarity (welding wire electrode)

　　2 if the elbow is generally suitable for the welding of 6mm sheet metal, has the characteristics of weld appearance, small welding deformation.

　　3 the gas is argon and the purity is 99.99%. When the welding current is 50~50A, the argon flow rate is 8~0L/min, when the current is 50~250A, the argon flow rate is 2~5L/min.

　　4 welding arc length, welding of ordinary steel, the 2~4mm is better, and the welding of stainless steel, to ~3mm for the best, too long, the protective effect is not good.

　　5 if pipe to prevent welding holes appear, welding parts such as rust, oil, make sure clean.

　　We have adopted advanced production equipment and technologies to manufacture our black steel pipe fittings elbow, which can not only improve product quality, but also save raw materials. Our products have high strength, good toughness and resistance to corrosion.
