Why weld overlay is required

A weld overlay is performed to protect the base material from wear or corrosive environments. The weld overlay layer is added as a cost-effective means to increase the base material's corrosion-resistance or mechanical properties

What is weld overlay cladding اعمال پوشش های سخت از طریق جوشکاری

Definition: A weld overlay is a type of cladding that uses a welding process to melt a material onto the surface of another, different material. A weld overlay is performed to protect the base material from wear or corrosive environments

Roundness tolerance

Roundness tolerance (+/- 0.01 inch) would mean the difference between major OD and the minor OD throughout the profile should not be greater or less than 0.01 inches. When bending round profiles to a certain radius, the greater the OD to bend radius, the higher ovality should be expected

ovality tolerance standard

This deviation is called ovality, and is defined as the difference between the maximum and minimum dimension of a tubes' outer diameter. Different industries and products may require varying ovality tolerances, ranging from 1.5% – 8%, depending on the end-use of the part
