一、焊造技术由来机械制造业获取毛坯件的传统方法主要是铸造和锻造,尽管近年来焊接技术在提供毛坯件的比重上日益增长,已接近铸、锻件两者的总和,但提供的形式仍限于铸-焊、锻-焊、轧-焊及冲-焊等“辅助”的地位。以独立形式提供成形坯件的焊造技术,在我国始于60年代初。1966年日本以“焊造法”命名发展为金属加工方法之一,经十余年来的进展,已初步提供轴类、管件、筒体和异形坯件,逐步建立铸造、锻造、焊造三“造”鼎立的局面。
First, the origin of welding technology Mechanical manufacturing to obtain rough parts of the traditional methods are mainly casting and forging, although in recent years the proportion of welding technology in the provision of rough parts is growing, is close to the sum of castings and forgings, but the form provided Still limited to cast - welding, forging - welding, rolling - welding and red - welding and other “auxiliary” status. In the form of independent provision of welding blank forming technology, in China began in the early 60s. Japan in 1966 to “welding method” named the development of one of the metal processing methods, after more than 10 years of progress, has initially provided shaft, tube, cylinder and shaped blank, and gradually establish the casting, forging, welding three “Made” the ultimate situation.
