Tree Method

In order to optimize electric- arc welding （ERW） welded tube scheduling , the paper introduces data cleaning, data extraction and transformation in detail and defines the datasets of sample attribute, which is based on analysis of production process of ERW welded tube. Furthermore, Decision-Tree method is adopted to achieve data mining and summarize scheduling rules which are validated by an example.

In experiment, worked out the parameters of deposition and the composition of the ferromagnetic charge, which ensure a defect-free weld layer (no pores, inclusions, hot and cold cracks) with a surface hardness of 52- 56 HRC without additional technological measures (heating products) and subsequent heat treatment.
