梳形电焊条熔槽焊接法是进行钢筋接头手工电弧焊接工艺中比较先进的方法,在没有阻焊机的情况下,我们在装配式桥螺纹钢筋骨架的钢筋对头焊接工艺中全面推广。有以下几点体会: (一)优越性 (1)提高了焊接效率。过去的对头焊接必须将钢筋接头踞成V形和用单焊条进行焊接,焊一个接头需40分钟左右的时间。采用此法仅3分钟(包括辅助工作时间),提高效率13倍。 (2)保证焊接质量。用梳形焊条熔槽焊接时电流较强,电弧温度较高,溶液较多,因此钢筋和溶液结合块,容易熔透,从而保证了焊接质量。
Comb-shaped welding electrode bath welding method is more advanced manual arc welding of steel joints in the more advanced method, in the absence of the case of welding machine, we assembled in the bridge rebar steel skeleton head to head welding process fully promoted. Have the following experience: (a) superiority (1) improve the welding efficiency. In the past, the butt welding had to entangle the reinforcing bar into a V-shape and weld it with a single welding rod. Welding a joint takes about 40 minutes. Using this method only 3 minutes (including auxiliary working hours), improve efficiency 13 times. (2) to ensure the welding quality. With comb-shaped electrode melting tank welding current, higher arc temperature, the solution is more, so the bar and the solution combination block, easy to penetrate, thus ensuring the welding quality.
