Wei Ouding earmarked for special welding brass brass welding wire TIG Siweiouding Description: Genuine Wei Ouding earmarked for special welding brass welding wire from Weiou Ding (Tianjin) Welding Technology Co., Ltd. Wei Ouding brass welding wire Profile: Wei Ouding 204S flame welding wire can replace resolved include dissimilar weld bronze, brass, steel, cast iron, zinc, galvanized iron, copper, and the metal between the welding efficiency is relatively high, especially for the thick brass, cast iron and copper, copper and stainless steel, cast iron and stainless steel welding dissimilar. Application: electrical equipment, deoxidized copper parts, panels, pumps, valves, marine bearing components, gears, casting repair Note: 1, oxide workpiece welding wire edges and surfaces, oil, dirt must be removed before welding may cause pores, slag and other defects, weld performance degradation. 2, when welding brass or bronze, as a relatively low melting point of the parent itself, so for special thin tube or plate welding material, please ensure proper formation of the weld puddle under the premise. 3, the butt joint is less than 3mm thickness, without groove; when the thickness is 3 to 10mm, open 60 ° ~ 70 ° V-groove; when the thickness is greater than 10mm, open 60 ° ~ 70 ° X-groove . To avoid incomplete penetration, usually without leaving a blunt edge. 4, the workpiece must be preheated before welding. Thickness less than 3mm preheating temperature of 150 ~ 300 ℃; when the thickness is greater than 3mm, the preheating temperature is 350 ~ 500 ℃. 5. When welding TIG welding positive polarity DC.
