Details not to be ignored in the welding of reinforced truss floor bearing plate

The application of reinforced truss floor bearing plate is becoming more and more extensive.  Welding is an indispensable part of the manufacturing and installation process.  Because, the importance of welding for the whole steel structure engineering will have a significant impact.  I'd like to talk to you about the inscrutable details of welding.  

【 Avoid welding deformation 】  

The deformation of the floor bearing plate caused by welding has a great impact on the construction quality. Therefore, the specific operation process and precautions of welding need to be strictly controlled during welding, such as the adjustment and control of the current size and so on.  At the same time, should also avoid in welding power failure.  Because, once there is a power failure, not only will affect the welding effect, but also likely to cause personal injury to the operator.  Therefore, one of the management work of the floor plate manufacturer is to check the welding environment and keep the welding machine dry and ventilated.  

【Implementation of segmented welding】

It is a good method to conduct multi-layer and multi-channel welding for reinforcing bar truss floor bearing plate welding. After each welding, the welding slag and spatter should be cleaned in time, and the defects affecting the welding quality should be dealt with first and then continued.  

【 Strictly control temperature 】  

Tip: If continuous welding operation is required, attention should be paid to controlling the temperature of the base metal in the welding area to ensure that the temperature between layers meets the requirements.  If there is a special case of interruption of welding, heat preservation measures should be taken. When welding again, repreheat the welding and the temperature should be higher than the initial preheat temperature.  

【 Check carefully after welding 】 

After the completion of the welding work, it is necessary to carefully check the surface for splash, welding slag, welding seam for edge bite, porosity, crack, welding tumor and other defects, as well as the geometric size of the weld surface meets the requirements.  

The welding work of reinforced truss floor bearing plate is an important link related to the overall quality of steel structure engineering, and also an important aspect which can reflect the management level of floor bearing plate manufacturers.  Every detail is permeated with the daily training and management of employees, and also shows the overall strength of steel structure manufacturers and whether they are responsible for customers.
