为了解决设备的不足,我厂利用半自动焊机的给送机构,制成一台土环缝自动焊接装置,进行多层高压容器的环缝焊接。其结构如图1所示。电动翻转台的焊接速度是固定的(31公尺/小时)。电气线路如图2所示,这种线路和一般洋焊机(例如AB及TC型的焊机)的不同点,在于避免了启动时焊丝上抽起弧的复杂性。焊接启动,不需要把焊丝与工件压得很紧,只要有点接触就能很顺当地引弧。经焊接操作证明,电气线路性能良好。用土环缝自动焊接装置焊接壁厚达110公厘的深坡
In order to solve the lack of equipment, I plant the use of semi-automatic welding machine feeding institutions, made of a soil ring seam automatic welding device for multi-layer high pressure vessel girth welding. The structure shown in Figure 1. Electric flip table welding speed is fixed (31 meters / hour). The electrical circuit shown in Figure 2, this line and the general foreign welding machine (such as AB and TC-type welding machine) the difference is to avoid starting arc welding arc complexity. Welding start, do not need the wire and the workpiece is pressed very tight, as long as a little contact can be very smoothly arc. The welding operation proved that the electrical circuit performance is good. Soil ring seam automatic welding equipment welding wall thickness of 110 mm deep slope
