一、前言在我厂与国外合作生产的起重机产品中,有许多直径为φ800mm～φ600mm,板厚32～54mm 的卷筒,由于卷筒直径太小,焊工进入卷筒内进行封底焊,劳动条件恶劣,且不能保证焊缝质量。为此,我们采用了单面焊双面成形粘接软垫的焊接工艺,得到了背面焊缝成形美观、光滑、无缺陷的优质焊缝,实践证明此法先进可靠,达到了国外合作厂家对卷筒焊缝质量的要求。二、粘接软垫简介
I. Preface In the crane products co-produced by our factory and abroad, there are many reels with diameter of φ800mm ~ φ600mm and thickness of 32 ~ 54mm. Since the diameter of the reels is too small, the welder enters into the reels to seal the backsheets. Working conditions Poor, and can not guarantee the quality of the weld. To this end, we have adopted a single-sided welding double-sided forming adhesive pad welding process, get the back of the weld forming a beautiful, smooth, defect-free quality weld, the practice proved that this method is advanced and reliable, reached a foreign partner Requirements for reel quality. Second, the introduction of adhesive pad
