Ball-milling is the most common process for graphene synthesis. In several studies, the mill was run in different features [2, 5, 8]. Edge-carboxylate graphite (ECG) was produced by ball milling and analysed by using a finite-element method. The ball-mill machine runs 48 times at 500 rpm, each time with 50 min of ball-milling and 10 min of rest.

Metal Inert Gas (MIG) welding is an arc welding process that uses a continuous solid wire electrode heated and fed into the weld pool from a welding gun. The two base materials are melted together forming a join. The gun feeds a shielding gas alongside the electrode helping protect the weld pool from airborne contaminants.
