铜和锌的合金叫黄铜,普通黄铜的机械性能和耐腐蚀性都比紫铜好,它能承受热压或冷加工,适宜制作各种构件和零件。我厂为某单位制作的装饰构件就是用黄铜板经卷圆焊接而成的,焊后经整形镀铬,使产品美观大方。下面将黄铜的钨极氩弧焊工艺介绍如下:一、焊前准备1.工件和焊丝的清理:焊件边缘和焊丝表面的油污在焊前必须用汽油或丙酮清理干净,清理宽度在20～30毫米左右。
Copper and zinc alloy called brass, ordinary brass mechanical properties and corrosion resistance than copper good, it can withstand hot pressing or cold processing, suitable for the production of various components and parts. Our factory is a unit made of decorative components is made of brass plate welded by the circle, the plastic after welding chrome, the product beautiful and generous. The following brass TIG welding process is as follows: First, the preparation before welding 1. Workpiece and wire cleaning: welding edge and welding wire surface oil before welding must be cleaned with gasoline or acetone, cleaning width of 20 ~ 30 mm or so.
