一种多段焊接成型工艺
摘要：
本发明公开了一种多段焊接成型工艺，具体步骤如下：步骤一，确认需要焊接的三段以上的焊接材料；步骤二，将第一段焊接材料和第二段焊接材料利用药芯焊丝进行焊接，然后测量第一次焊接后产品的同心度和抗折强度并且进行对比；步骤三，将第三段焊接材料和第二段焊接材料利用药芯焊丝进行焊接，然后测量第二次焊接后产品的同心度和抗折强度并且进行对比，对焊接合格的焊接处进行打磨、抛光和低温热处理；步骤四，重复上述步骤三，直至所有焊接材料均焊接完毕，即可得到所需产品。本发明公布的多段焊接成型工艺，操作简单方便，花费时间少，可以将不同的材料焊接在一起，焊接后的产品同心度和抗折强度好，应用前景广阔。
摘要（英）：

The invention discloses a multi-section welding forming technology. The technology comprises the following steps that 1, three or more sections of welding materials to be welded are determined; 2, the first section of welding material and the second section of welding material are welded by means of a flux-cored wire, and then the concentricity and breaking strength of a product obtained after first-time welding are measured and compared; 3, the third section of welding material and the second section of welding material are welded by means of a flux-cored wire, then, the concentricity and breaking strength of a product obtained after second-time welding are measured and compared, the qualified welding position is ground, polished and subjected to low-temperature heat treatment; 4, the step 3 is executed repeatedly till all the welding materials are welded thoroughly, and the needed product can be obtained. According to the multi-section welding forming technology, operation is easy and convenient, the consumed time is short, different materials can be welded together, the concentricity and breaking strength of the welded product are good, and the application prospect is wide.
