一般比較厚的鋼板(20公厘以上)都是用气焊切割的。当切断較长的鋼板时,操作同志的劳动强度很大,而且切断的痕迹不直,往往給以后的加工造成困难。我厂气焊工人聶瑞先同志改进了一付工具,完全可以克服这个缺点,提高了生产效率。工作时把焊咀套在1处,使焊咀同切割材料保持一定距离;然后握住手把2,向人身方向移动,滾动輪3便沿直綫前进进行切割了。
Generally thicker steel (20 mm above) are cut with gas welding. When cutting a long steel plate, operating gay labor intensity is great, and cut off the traces are not straight, often to the subsequent processing difficulties. Our factory gas welder Nie Ruixian comrades improved a pair of tools, can completely overcome this shortcoming, raised production efficiency. Welding tip set work at 1, so that welding tip with the cutting material to maintain a certain distance; and then hold the handle 2, to the direction of personal movement, rolling wheel 3 will be along the straight forward cutting.
