introduction
As a key protective layer for steel pretreatment, shop primer is widely used in steel structure, shipbuilding, automobile manufacturing and other fields. Its performance is directly related to the
It affects the quality and safety of subsequent processes such as welding and cutting.
GB/T 46087 “Shop primer welding and related process tests” aims to build a complete shop primer process evaluation system, including shop primer
The effects of paint on welding performance, thermal cutting efficiency and smoke emissions are divided into the following four parts.
--- Part 1.General requirements. The purpose is to specify the basic conditions, term definitions, environment and safety requirements for the test, and to provide guidance for subsequent tests.
Provide a unified framework.
--- Part 2.Welding performance. The purpose is to evaluate the welding performance of shop primers by using the severity of welding porosity defects
impact.
--- Part 3.Thermal cutting. The purpose is to clarify the test method for the maximum speed of thermal cutting of shop primers, through standardized test pieces
Preparation and cutting parameter setting, evaluation of the effect of primer on cutting efficiency and process stability.
--- Part 4.Emissions of smoke and gases. The purpose is to establish an evaluation system for the emission levels of smoke and harmful gases from shop primers.
System, providing a technical basis for reducing occupational health hazards and environmental pollution.
