The shape of the ERW welded steel pipe welding heat affected zone is closely related to the selection of welding process parameters.
In the case of qualified ERW welded steel pipe produced by our company (such as chemical composition, mechanical properties, and grain size of metallographic structure F + P), the width of the heat affected zone of the weld, Measured data of fusion line width and metal streamline angle.
Two types of steel pipes can also be distinguished according totheir properties and uses, and then reasonable steel pipes are selected for construction.
