This process is applied in various construction of engineering materials both on land and underwater environments such as in ship construction, oil and gas mining in the middle of the sea and nuclear power plants. Material construction greatly influences the method suitable for the welding process. It will affect the evolution of the microstructure and mechanical properties of the material. So, it will affect the results of the welded joint. © 2020 The Authors. Published by ELSEVIER B.V.

Introduction Welding is a method of joining the process of materials, especially metal materials that have been carried out for years with implementation, e.g., on land-marine structures (Bae et al., 2016a, b) and transportation modes (Cao et al., 2016; Muttaqie et al., 2019). This process is carried out by joints two similar or dissimilar metals by heating to melt the parts together, then allowing them to cool and may be joined together. The welding process can be carried out in a variety of engineering materials construction, either on the land or water environment (Yohanes et al., 2018). Underwater welding is generally used to repair and maintain pipeline construction on the underwater, ship components, port construction, and the structure of nuclear power plants (Guo et al., 2015).
