As a professional in the field of metallurgy and welding, I have extensive experience with various types of metals, including forged steel. Welding on forged steel is a common practice in the industry, and it's essential to understand the unique properties of forged steel to ensure a successful and high-quality weld. Forged steel is known for its enhanced mechanical properties and microstructure, which result from the forging process that involves heating and hammering the steel to refine its grain structure and eliminate any internal defects.
**Step 1: Material Selection and Preparation**
Before you begin welding, it's crucial to select the appropriate material for the base metal and the filler metal. The ASME Section VIII Division 1 provides guidelines for welded construction and includes clauses that address the welding of forged products. The choice of filler material should be compatible with the base metal to ensure proper fusion and to achieve the desired mechanical properties in the welded joint.
Step 2: Preheat and Temperature Control
One of the key considerations when welding forged steel is the need for preheating. Preheating helps to reduce the thermal stress and the risk of cracking. The temperature for preheating and the interpass temperature (the temperature between successive weld passes) should be carefully controlled. The specific temperatures will depend on the steel's composition and the thickness of the material being welded.
Step 3: Welding Process Selection
Forged steel can be welded using various methods, including gas tungsten arc welding (GTAW), shielded metal arc welding (SMAW), gas metal arc welding (GMAW), and laser beam welding (LBW). The choice of welding process will depend on factors such as the thickness of the material, the required precision, and the equipment available. Each method has its advantages and limitations, and the selection should be based on the specific application and the desired outcome.
Step 4: Post-weld Heat Treatment
After welding, it's often necessary to perform a post-weld heat treatment (PWHT) to relieve any residual stresses and to ensure that the mechanical properties of the base metal are maintained. The type of heat treatment and the temperature used will depend on the grade of the forged steel and the specific requirements of the project.
Step 5: Inspection and Testing
Finally, the welded joint should be thoroughly inspected and tested to ensure that it meets the required standards. This may include visual inspection, non-destructive testing (NDT) such as ultrasonic testing (UT) or radiographic testing (RT), and mechanical testing to verify the strength and integrity of the weld.
In conclusion, welding on forged steel is a meticulous process that requires careful planning and execution. By following the guidelines provided by ASME Section VIII Division 1 and adhering to best practices in the industry, it's possible to achieve a high-quality weld that meets the stringent requirements of various applications.

As per ASME section 8 div I there is clauses for forged product that how to weld that forged steel. Forged steel can be welded by any method steel can be welded gas, electric or laser. Forged steel is just steel and you just have to pick the most convenient method that you have available, whichever one that is.
