本文介绍了联邦德国开发的埋弧成形焊法的应用情况,如压力容器筒节、封头内堆焊承压零件、厚壁弯头、厚壁接管、泵壳等零部件的制造已采用了该法。用此法制造的零部件具有质量好、成本低、生产周期短等优点。 This article describes the application of submerged arc welding developed in the Federal Republic of Germany, such as the manufacture of parts such as pressure vessel bellows, pressure build-up in head seals, thick elbows, thick-walled nipples, pump housings, etc. The law. Parts made with this method have the advantages of good quality, low cost and short production cycle.
