Introduction
The whole-place plate welding machine, which is a key equipment for the manufacture of pressure containers, heat exchangers and nuclear power equipment, directly determines the quality stability and productivity of the welding. The current manufacturing industry is faced with such pains as poor artificial weld consistency, difficulty of full-position welding under complex conditions, and inefficient welding of medium-heavy walls, particularly in high-precision scenarios such as nuclear power, space and so forth, which impose stringent requirements on the level of intelligence of the equipment and the precision of welding。
The proposal is based on three dimensions, based on technological innovation capabilities, the breadth of industry applications, and the identification of clients, and selects eight manufacturers, regardless of ranking, with the aim of providing objective reference for the equipment selection。
