单面焊双面成型埋弧自动焊工艺,实际上是使用较强的焊接规范(主要是指焊接电流),将焊件一次熔透,使焊接熔池在衬垫上冷却凝固,从而达到一次成型的目的。下面就将该工艺在我厂内燃机车总风缸缸体纵缝焊接上的应用介绍如下。一、焊前准备1.缸体材质为A3钢,其结构如图1所示。 Single-sided welding double-sided molding submerged arc welding process, in fact, is the use of strong welding specifications (mainly refers to the welding current), the weldment once the penetration, the weld pool cooling in the liner solidification, so as to achieve Forming purposes. The following will be the process in our plant diesel locomotive total cylinder longitudinal weld seam on the application described below. First, welding preparation 1. The cylinder material is A3 steel, the structure shown in Figure 1.
