Methods for cleaning stainless steel roots
Thread Content
What method is used to clean the roots of stainless steel? Can it be done using carbon arc gouging and grinding with a wheel?
After root cleaning, the oxide layer must be polished thoroughly to prevent cracks in the stainless steel caused by high carbon content.
First, use a carbon arc gouging machine to remove the weld until no cracks remain, and then grind it with a grinder
It is possible to use carbon arc gas gouging; the key is to grind the carburized layer clean
It is recommended that TIG welding be used as the root pass for welding stainless steel, in order to avoid the need for root cleaning resulting from direct welding using submerged arc welding or manual arc welding, which could affect the quality of the weld seam, as well as surface contamination of the container caused by gas cutting. If root cleaning is necessary, a plasma planer can be considered, which can also prevent carburization. When using a grinding wheel for polishing, special stainless steel grinding wheels must be used.
The inspection team said no, as it would affect the organization of the materials. :L
The inspection team said no. . Just go ahead and execute it. . Change it to grinding with a grinder. . .
All are processed using carbon arc gas gouging, and then carefully polished
Use a plasma arc gouging method to clean the root – there’s no problem with that.
To prevent carburization, many companies do not allow the use of carbon arc gas gouging; it’s better to use mechanical cleaning methods, such as grinding with a grinder~~
