铝合金压铸模具属于易损耗模具,在经过2万到5万次时使用后,很容易出现龟裂、磨损等质量问题,这时,就需要对铝合金模具进行焊接修复。就目前来说,我国的铝合金焊接修复工艺还不成熟,焊接的成功率不高。本文对我国常用的焊接材料和焊接方式进行了简单的介绍,并详细介绍了焊接作业的步骤,希望能够给从业人员提供帮助。
Aluminum die-casting molds are easy to wear mold, after 20,000 to 50,000 times when used, it is prone to cracking, wear and other quality problems, then the need for aluminum mold welding repair. For now, China’s aluminum alloy welding repair process is not yet mature, the success rate of welding is not high. This article gives a brief introduction of welding materials and welding methods commonly used in our country, and introduces the steps of welding operation in detail, hoping to provide help to practitioners.
