Welding length obtained from one welding rod is short.
一根焊条所得到的焊缝长度有限。
So the control of the welding parameter such as welding pressure, gas flux, upsetting length is realized, and the system has a high dynamic response rapid and a high control precision.
从而成功地实现了对气压焊的焊接压力、气体流量、顶锻位移量等焊接过程参数的控制，并使控制系统具有较快的动态响应速度和较高的控制精度。
Such problems in accessary welding as insufficient weld depth and length, and poor visual quality will cause future safety problems.
一些附件焊高不够、焊缝长度不足及焊缝外观质量差等施工安装问题，都会对安全生产留有后患。
