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.

Shop Primer

prefabrication primer During the steel production stage, it is evenly applied on the surface of the sandblasted steel plate as a primer for surface corrosion protection. It can directly protect the painted steel.

Welding and cutting are then carried out.

Test method for evaluating the effect of shop primers on the thermal cutting properties of steel using cutting speed as the only measured variable.
