待焊接工件及焊接方法
摘要：
本发明提供了一种待焊接工件及焊接方法，其中，待焊接工件包括工件本体，工件本体包括待焊接部(10)及凸出部(20)，待焊接部(10)包括待焊接边沿(30)及与待焊接边沿(30)相邻的两个端部边沿(40)，每个端部边沿(40)上设置有凸出部(20)，凸出部(20)与待焊接部(10)一体成型，凸出部(20)的一个边沿与待焊接边沿(30)对齐或者突出于待焊接边沿(30)。本发明的技术方案能够有效地解决现有技术中的直缝焊接的起弧、收弧处质量存在缺陷，并且焊接操作复杂、生产效率低的问题。
摘要（英）：

The invention provides a workpiece to be welded and a welding method. The workpiece to be welded comprises a workpiece body. The workpiece body comprises portions (10) to be welded and protruding portions (20). The portions (10) to be welded comprise edges (30) to be welded and two end edges (40) adjacent to the edges (30) to be welded. Each end edge (40) is provided with the corresponding protruding portions (20). The protruding portions (20) and the portions (10) to be welded are integrally molded. One edge of each protruding portion (20) is aligned with the corresponding edge (30) to be welded or protrudes out of the corresponding edge (30) to be welded. By the adoption of the technical scheme, the problems that the quality of arc starting and stopping portions in straight joint welding is poor, welding operation is complex, and production efficiency is low in the prior art can be effectively solved.
