Abstract

This paper introduces the TIG welding process of duplex stainless steel 2205 under the type of 1.2 mm thin plate end joint. Starting from the characteristics and appli-cation of 2205

the weldability of materials

welding process parameters and operation essentials

it emphatically analyzes the problems（uneven metallographic structure） that are easy to occur in the process of thin plate end welding

and the relevant process measures and measures to solve the defects.
