Dear sir, 1. If you looking for complete penetration then PQR rejected with following details for understanding. Yes it will be like concave, I agree with you . Until it not fully penetrated will not get fusion .  These is problem due to gas cup nozzle size diameter sticking with faying surfaces of wall thickness & higher arc length not advisable in welding. Generally, AWS D1.1-2015 PG 97 Preqaulification .  Will give you idea about root opening range from Min 5 to Max 12 mm ( tolerances added ) in your case 4 mm.

Dear Dinesh,  Thanks for Quick Reply  appreciated . Sir, The Root Gap is 4mm we are welding it FCAW process Size is 1.2, it can be fusion with backing plate. However As per the AWS  4.9.1.1 (3)the weld shall be complete fusion (fig 5.4) . If we refer Macro photograph it is not fused with backing plate also it is in concave fusion.  Can be passed or reject the PQR.  Regards, HIREMATH  On 30-Nov-2017, at 9:04 AM, Dinesh Somwanshi < som.din@gmail.com > wrote: Dear ,, 1)       As per the Weld Joint Preparation is "Single Bevel" But after welding it seen like "Single Vee" with other side bevel of 10 °  –    What Joint configuration will be Considered in the PQR / WPS as Result   -- Single V 2)       The attached Macro Photograph is seen that Root is not Penetrated with Backing Plate. – is this Result shall be Passed or failed.  First thing i understand you looking for full pene...

It cause ARC improper fray at root pass location. You must maintain ROOT gap IF looking for it. With Micros it looks like faying surface has better control over hot , fill , cap .   Thanks & Regards DINESH VITTHAL SOMWANSHI BACHELOR IN MECHANICAL ENGINEER Skype = dinesh somwanshi असो द्यावी दया तुमच्या लागतसे पाया. *Pray for others, sometime, You might ne...

A 16-inch diameter pipe of schedule 120 has a 1.219-inch thickness. An 8-inch diameter pipe  of schedule 120 has a 0.719-inch thickness. Since the 8-inch weldolet is SA-335-P11, presumably so too is the 16-inch pipe, which is an ASME P-No. 4 classification. Presuming that the weldolet attachment weld is a full penetration weld into the pipe, then the controlling, or governing, thickness of the weldment assembly is 1.219 inches. Therefore, the PWHT soak time must be a minimum of 1-1/4 hours. However, it there is a finishing fillet weld whose throat thickness exceeds the pipe thickness, then the throat thickness governs the PWHT soak time, at 1 hr/inch of thickness.   Regards, D.
