Re: [MW:26258] can we use a wps which is qualified under asme b31.3 for 31.1 piping

Dear Sir,

B31.1 & B31.3 are the construction codes for the particular piping . WPS , WPQR and Welder qualifications are based on AWS D1.1, ASME sec IX and API 1104. You have to refer the Project QAP and Approved Procedures by the Owner.

Thanking You.

With Warm Regards,

Dear Experts,
As per ASME Sec IX if for small diameter we have to done qualification e.g. 1/2" dia . Pipe we will have to take multiple specimen to cover the 150 mm length for RT, and also we Can't take specimen more than 4 nos.
I have query which dia we will have to consider for qualification of welder it's Outer dia. Or Inner dia of pipe for circumference length calculation because if we will consider inner dia for calculation then we will have to take more than 4 specimens and which violates the code .
Best Regards,Mohit Aggarwal

Re: [MW:26253] Shielding gas for GMAW pulsed welding-Carbon Steel

Voltage anything less than 21v goes to short circuit, but in ur case Voltage is ok, but increase the current to minimum 250amps, Do not put in Synergy mode and set the Current as required.

Dear Mr Pandithan,
In the machine I have selected the pulse mode itself. (GMAW-P). The position I am using is IG(rotating ) . As I am using the synergy mode in the machine the current and voltage is getting selected automatically when I am giving the wire feed speed. I am using the wire feed speed of 9.5 m/min, the voltage coming is in range 25V -28V and current in range 215 to 230. How to ensure I am not using the short circuiting mode?? I am using this process for pipe welding which includes both high a…

Re: [MW:26252] E6010 electrode for root

Dear Sir,

For larger bore E6010 shall be used as it gives deep penetrationbecause of it is shielded with cellulose flux. There is no restriction in B31.3 for using E6010.

Thanking You.
