这里介绍的五种改进焊件设计,减少焊接加工费用或方便操作的实例。一、保证图纸尺寸简明在图纸上尽可能用长度尺寸标注,避免角度注法。图上角度使车间工人必须用量角器或通过计算才能制出零件来(见图1)。二、减少金属填料消耗焊接接头的设计应尽量减少金属填料存留数量。J形坡口焊接需要填料要比斜坡口接头少,而且便于接近根部。图2中把一英寸厚板45°斜坡口与15°J形坡口进行比较,改为J形坡口所节省的金属填料和减少焊接 Here are five examples of improved weldment design that reduce the cost of welding or ease of operation. First, to ensure that the drawings are simple in size Drawings on the length dimension as far as possible to avoid the angle Note. The diagram shows the workshop workers must use protractor or by calculation to make parts (see Figure 1). Second, to reduce the consumption of metal filler welded joints should be designed to minimize the amount of metal filler retention. J-shaped bevel weld requires less filler than the bevel joints, and easy access to the roots. In Figure 2, a one-inch thick 45 ° bevel and a 15 ° J-bevel are compared to the metal fillers saved by the J-bevel and the welding is reduced
